Well, when I start my rendering, everyrhing works OK and I can pick any actor I want. Now, when I put the camera on the back of the scene (lets say Azimuth = 180), and I have two actors aligned, it picks the one that is on the BACK instead of the one on the FRONT! Any idea?

Use vtkCGMWriter to write a scene to file. This class is included in vtk4.n but it is not built... so you have to add it yourself to the cmake files and re-compile. Under windows and the borland compiler there were a couple of small bugs. Email me if they cause you any problems. 2. Download and install the universal postscript printer driver from adobe. 3. Insert the CGM file into a Word document. Make sure Word has the CGM graphics importer installed 4. Print the Word page to a PS file using the PS printer driver. 5.

Maybe the problem was there. I don't know the following may help or not, but in an old code I had the filename also as the last argument of gl2psBeginPage{...char *filename; File *fp = fopen(filename,"w");...;gl2psBeginPage(...,filename);...}.

I'm not the expert on this since David Gobbi wrote the implementation but here is my explanation of how things work. I'll let David correct me if I'm wrong. The VTK-Python wrappers are a thin layer around the VTK library. As you must be aware, VTK has its own reference counting mechanism. When a VTK object is used by another the object increases the reference count of the object it uses. When it no longer needs the object the objects refcount is decremented and when it drops to zero the object is destroyed. Its the same as in Python. So here is an example demonstrating how it all works: >>> import sys >>> import vtk >>> cs = vtk.vtkConeSource() >>> out = cs.GetOutput() >>> print sys.getrefcount (out) 2 >>> print out.GetReferenceCount () 3 >>> m = vtk.vtkPolyDataMapper() >>> m.SetInput(out) >>> print out.GetReferenceCount() 4 >>> print sys.getrefcount (out) 2 >>> o = out >>> sys.getrefcount (out) 3 >>> print out.GetReferenceCount () 4 # Now how are objects deleted? >>> print cs.GetReferenceCount() 3 >>> print sys.getrefcount(cs) 2 # Now turn on debug to see if the object is indeed deleted. >>> cs.DebugOn() >>> del cs Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 230 vtkConeSource (0x819e468): UnRegistered by NULL, ReferenceCount = 2 Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 230 vtkConeSource (0x819e468): UnRegistered by NULL, ReferenceCount = 1 >>> # this object is not deleted because out still holds a reference # internally. >>> del out # still nothing happens because GetOutput() is still held by the # mapper. >>> del m Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 225 vtkConeSource (0x819d1d0): UnRegistered by vtkPolyData (0x8136640), ReferenceCount = 0 Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 126 vtkObject (0x819d1d0): Destructing!

How about the following: Take the case where I want to replace a section of the visualisation pipline. Source->Filter1->Filter2->Mapper If I disconnect the pair of filters (for example) by resetting the inputs and outputs of the mapper and source respectively, to replace them with some other filters, how do I destroy the redundant Filter1 and Filter2? According to my understanding, using del Filter1 del Filter2 will simply remove the label for each filter (hence decreasing their ref-counts by one). However Since the filters are still connected to each other, they still have references >=1 so are not destroyed. Thus I must break the connection between the filters before they are destroyed. How do I do this? Can I set their inputs to NULL?

Message-ID: <001701c26a2c$31a81700$b92d8280@atp.tuwien.ac.at> Dear vtk-users! For my "CAD-like" application I need serveral (4) views (front, top, left, perspective) of the same set of actors. I am new to VTK, so I first modified the "...GUI\Win32\SampleMFC" and added a CSplitterWnd to the childframe. The behavior of this was little strange: in some panes (of the splitterwnd) the actors were not rendered. I read the mailinglist and noticed that each renderwindow needs his own actors and mappers. So I rewrote the mfcsample and added an actor and a mapper to each view sharing the same "vtkPolyData" as input. Now erverything works fine until I maximize the CChildFrame: If I use the Inteactor of the bottom-left pane, the renderd scene is displayed in the top-right pane. (ImmediateModeRenderingOn() had no effect on this) (I am using vtk 4.0 and WIN98) Can anybody tell me what is going wrong, or is there an example of how to use splitterwindows or multiple views with VTK?

It's an airplane's flight track, so I have lat/long and altitude info and also some onboard instrument data. The coords and altitude map nicely into the xyz point coordinates. I would like the instrument data to be the scalars for the polydata line that gets created. But I have two sets of data and the vtk data file format (.vtk) only seems to allow one set of plain scalars, can't have scalars with more than one component. I guess I could add the second set by hand, but I would like to know if there is anything I can do to just put all the data into one vtk datafile, so I can just use vtkPolyDataReader to read it all and assemble it correctly.

You can enter as many scalar/vector fields as you want using the FIELD tag in the polydata file: FIELD .... for example, a single scalar field of 300 floating point numbers might look like: FIELD extraScalar 1 InstrReading 1 300 float 1.2 1.4 1.2 1.7 .....

I tried to compile the nightly release from today using cygwin and gcc-2.95-3, but during the linking stage of the libvtkRendering library I always have the problem that the references to all the open gl functions are undefined : (last line of error messages for static libraries): ... /cygdrive/g/Tools/VTK/bin/libvtkRendering.a(vtkWin32OpenGLTextMapper.o)( 3b45):vtkWin32OpenGLTextMapper.cxx: undefined reference to `glPopMatrix' collect2: ld returned 1 exit status make[3]: *** [/cygdrive/g/Tools/VTK/bin/vtk] Error 1 make[2]: *** [default_target] Error 2 make[1]: *** [default_target_Wrapping_Tcl] Error 2 make: *** [default_target] Error 2 A similar problem also occurs if I try compile shared libraries, only then the linker already complains when it tries to build the library libvtkRendering.dll (also with undefined references to open gl calls). I have the cygwin open gl files installed (/usr/lib/include/GL/gl.h , /usr/lib/w32api/opengl32.a) and the opengl32.dll from windows is in the cygwin path. Does anybody have any hints how I can get this to work? Are there any special flags for cygwin/opengl that I need to set in the CMake config files?

It seems that the vtkVolume class provides the functionality I need in a prop/actor. However, vtkVolume is constrained to using a vtkVolumeMapper, which is constrained to using a vtkImageData as its input. This is a problem because I want to build a volume rendering mapper that accepts a vtkUnstructuredGrid as its input. Is there a way to use the vtkVolume class with mappers that do not render vtkImageData, or is there a trivial change that could be made that would allow it to? Adding a vtkAbstractVolumeMapper between vtkAbstractMapper3D and vtkVolumeMapper might do the trick. Or is it really necessary to write a separate prop class for volume rendering each of the vtkImageData, vtkRectilinearGrid, vtkStructuredGrid, and vtkUnstructuredGrid data object types? -Ken **** Kenneth Moreland *** Sandia National Laboratories *********** *** *** *** email: kmorel@sandia.gov ** *** ** phone: (505) 844-8919 *** fax: (505) 844-9297 ------_=_NextPart_000_01C26A5A.3E0856D0 Content-Type: application/ms-tnef Content-Transfer-Encoding: base64 eJ8+IiEVAQaQCAAEAAAAAAABAAEAAQeQBgAIAAAA5AQAAAAAAADoAAEIgAcAGAAAAElQTS5NaWNy b3NvZnQgTWFpbC5Ob3RlADEIAQWAAwAOAAAA0gcKAAIADwAZACIAAwAyAQEggAMADgAAANIHCgAC AA8AGQAfAAMALwEBCYABACEAAAAzNzZFQTZFQjY3MzhEMDQzOTQ1MkYwNkE2NTk3RkE4NQAmBwEE gAEALwAAAFZvbHVtZSByZW5kZXJpbmcgZGF0YSB0aGF0IGlzIG5vdCB2dGtJbWFnZURhdGEAIBEB DYAEAAIAAAACAAIAAQOQBgCcCAAALQAAAAMAAoAIIAYAAAAAAMAAAAAAAABGAAAAAFKFAAB9bgEA HgADgAggBgAAAAAAwAAAAAAAAEYAAAAAVIUAAAEAAAAEAAAAOS4wAAsADYAIIAYAAAAAAMAAAAAA AABGAAAAAAaFAAAAAAAAAwAEgAggBgAAAAAAwAAAAAAAAEYAAAAAAYUAAAAAAAALAACACCAGAAAA AADAAAAAAAAARgAAAAADhQAAAAAAAAsABYAIIAYAAAAAAMAAAAAAAABGAAAAAA6FAAAAAAAAAwAB gAggBgAAAAAAwAAAAAAAAEYAAAAAEIUAAAAAAAADAAaACCAGAAAAAADAAAAAAAAARgAAAAARhQAA AAAAAAMAB4AIIAYAAAAAAMAAAAAAAABGAAAAABiFAAAAAAAAAgEJEAEAAACxAwAArQMAAP0FAABM WkZ1DEIY2QMACgByY3BnMTI14jIDQ3RleAVBAQMB9/8KgAKkA+QHEwKAD/MAUARWPwhVB7IRJQ5R AwECAGNo4QrAc2V0MgYABsMRJfYzBEYTtzASLBEzCO8J97Y7GB8OMDURIgxgYwBQMwsJAWQzNhZQ C6YgSUIgE+B2ZSBiCeEgKQGQc2sJgCAD8HRojCBwF8ELgGcgcwNwmR1Ab2YfMAhwIHUAgLR0chrQ dAhwHfF2BvD2dR8RGCBuBIEesQqiCoAHBaABAB2gbyBWVEvmIABwHgBhbR0CHrIf4McIYAJgHUBm aWcIcR7BMwhgBUBobwfgIjFhZH0eAGMLYAQQB5EiMR5AZdMhhADAcHAEkC8A0CIwfwXAJYMdAAiR CsAT0AiQc5wuIBzgBUAUEGVtJeGPE+AFQCYxIHB0a1YglN0nlHADYCMwAQBzIYQpsnZmH7AgEGkC IAdAHjB5fRzhbgngHgALgCKQKuJwKyckKKFIJOBlHTByLP8p6QQAJXACIB/RC3EJgCt1vSJAdQCQ HsEtkCn3TSbTfS7wdyfwE9AvrSIiMSlJ8QDAZ2VEKYAtkB3AIYS3HjAEIAuAcCSgKKFUJ/A/NiEE IC2TI8Ei8B1gY2F3MSAdQBzwdwBwKZEiQGJ+dQMQIsEgfyZqKVQA0GOuZQUwNyIp8VUfyUcFEN8i wTYhNhchhCGESSlCBJD/HUAtkDiALNAw8yIRKc8EIJceIybEKUVkIkBubwVA/yD0IYQ0ui7wBbEv sT9GH+D+aSMwB0AlcBPgHsBAUimBfQWgdTkxHWBB8SICKXJ3f0cSIYQHQBewB+AeMCIhP80osEEl UDFHQWIwEiAQezHaHVF0LqAdgUpZMjQzvkRIhSKxMa1B8CQQaEKz00ByRcFjayihT0TzSUH/GCBI 4SzQLRA7wAQQCsA/4/53BRAOsEiFKPEKsSmAHUDfLbInhQIQBcA5jiBREDLh7x9BQHVEOEOnUgWQ HqAsoO8tEArAPTIu81M8qy7wTeVtPH9kNUI3gGpX0St1eckm8HM/PlotSwnwPlr5KLAgKl7hXrFe sV3BLRD1HkFNBbBlC2AhEF5XXtJvXyQGEUngLZBOKYAsYyD+TAGgBbApgAWwKHEhhF7if2PVKLBj d2ETXvMpIAtwbNg6IGsEYGAhQFHAYdK8LmcrEGN2YQVfAnAk0AMtEGYgKDUwNSkgADg0NC04OTE5 42CPKLBmYXhmICiwaPhQOTI5NyGEfWzAAAAAHgBwAAEAAAAvAAAAVm9sdW1lIHJlbmRlcmluZyBk YXRhIHRoYXQgaXMgbm90IHZ0a0ltYWdlRGF0YQAAAgFxAAEAAAAWAAAAAcJqWj7PZaRDQp70Qdyw wZiCtUhdyAAACwACAAEAAAADAAlZAQAAAAMA3j+vbwAAQAA5ANBWCD5aasIBAwDxPwkEAAAeADFA AQAAAAcAAABLTU9SRUwAAAMAGkAAAAAAHgAwQAEAAAAHAAAAS01PUkVMAAADABlAAAAAAAMA/T/k BAAAAwAmAAAAAAADADYAAAAAAAMAgBD/////AgFHAAEAAAAwAAAAYz1VUzthPSA7cD1TTkw7bD1F UzA0U05MTlQtMDIxMDAyMjEyNTM0Wi0zODM1NTYAAgH5PwEAAABEAAAAAAAAANynQMjAQhAatLkI ACsv4YIBAAAAAAAAAC9PPVNOTC9PVT1TRUVNUy9DTj1SRUNJUElFTlRTL0NOPUtNT1JFTAAeAPg/ AQAAABIAAABNb3JlbGFuZCwgS2VubmV0aAAAAB4AOEABAAAABwAAAEtNT1JFTAAAAgH7PwEAAABE AAAAAAAAANynQMjAQhAatLkIACsv4YIBAAAAAAAAAC9PPVNOTC9PVT1TRUVNUy9DTj1SRUNJUElF TlRTL0NOPUtNT1JFTAAeAPo/AQAAABIAAABNb3JlbGFuZCwgS2VubmV0aAAAAB4AOUABAAAABwAA AEtNT1JFTAAAQAAHMAbySBNaasIBQAAIMAwnwTxaasIBHgA9AAEAAAABAAAAAAAAAB4AHQ4BAAAA LwAAAFZvbHVtZSByZW5kZXJpbmcgZGF0YSB0aGF0IGlzIG5vdCB2dGtJbWFnZURhdGEAAB4ANRAB AAAAMwAAADxCNTFGMEM2MzZFNTc4QTRFODMyRDM5NTg2OTBDRDczRUQyMEQzRUBlczA0c25sbnQ+ AAALACkAAAAAAAsAIwAAAAAAAwAGEMyThXgDAAcQpwMAAAMAEBAAAAAAAwAREAAAAAAeAAgQAQAA AGUAAABJSEFWRUJFRU5UQVNLRURXSVRIUE9SVElOR1NPTUVPRk9VUlVOU1RSVUNUVVJFRFZPTFVN RVJFTkRFUklOR0NPREVUT1ZUS0FOREFNSEFWSU5HVFJPVUJMRUZJR1VSSU5HT1VUAAAAAAIBfwAB AAAAMwAAADxCNTFGMEM2MzZFNTc4QTRFODMyRDM5NTg2OTBDRDczRUQyMEQzRUBlczA0c25sbnQ+ AABgIQ== ------_=_NextPart_000_01C26A5A.3E0856D0-- From c.p.botha@its.tudelft.nl Wed Oct 2 23:00:23 2002 From: c.p.botha@its.tudelft.nl (Charl P.

Under JDK 1.4.0 the vtkPanel (version 4.0) won't work because it is in an un-named package. I'm not sure if this is the case in JDK 1.3.1. The problem is fixed in the nightly source release; try building that.

I am revising an application from using VTK 3.1 to 4.0 and I ran into an inconsistency in the result returned by vtkCamera::GetOrientationWXYZ. This is illustrated by the following C++ sample code: #include "vtkCamera.h" void main() { vtkCamera *cam = vtkCamera::New(); cam->SetPosition(40.5388, -58.1675, 36.4357); cam->SetFocalPoint(12.5875, 11.3799, 10.3485); cam->SetViewUp(-0.221512, 0.263181, 0.938972); cam->ComputeViewPlaneNormal(); // Needed for VTK 3.1 cam->OrthogonalizeViewUp(); float *wxyz = cam->GetOrientationWXYZ(); cout << wxyz[0] << " " << wxyz[1] << " " << wxyz[2] << " " << wxyz[3]; } When run using VTK 4.0 (nightly release, Oct 1, 2002), I get 284.514 0.937559 0.129517 0.322812 When run using VTK 3.1, I get 75.4863 0.937559 0.129517 0.322812 The first number (angle) differ in the two results. I think the number returned by VTK 4.0 is incorrect for the following reason. The method vtkCamera::GetOrientationXYZ() is used only in 2 classes, one of which is vtkVRMLExporter. In VTK3.1, vtkVRMLExporter generates a correct vrml file. In VTK4.0, vtkVRMLExporter does not generat a correct vrml file (the viewpoint is oriented in the wrong direction). Tracking the computation through the source code of VTK 3.1 versus 4.0, the main difference occurs in the row-column indexing of the matrix in the class vtkTransform. In particular, the method vtkTransform::GetOrientationWXYZ() is void vtkTransform::GetOrientationWXYZ(double wxyz[4]) { int i; this->Update(); // convenient access to matrix double (*matrix)[4] = this->Matrix->Element; double ortho[3][3]; for (i = 0; i < 3; i++) { ortho[0][i] = matrix[0][i]; ortho[1][i] = matrix[1][i]; ortho[2][i] = matrix[2][i]; } //...etc where ortho is subsequently used to compute w,x,y,z. If I transpose the ortho matrix, that is, change the above loop to for (i = 0; i < 3; i++) { ortho[i][0] = matrix[0][i]; ortho[i][1] = matrix[1][i]; ortho[i][2] = matrix[2][i]; } and rebuild VTK 4.0, then the above sample program gives the same result as that of VTK3.1. Also, the vrml file exported by vtkVRMLExporter is correct (viewpoint looks at the correct direction). The above suggests that either (1) the elements in the matrix of vtkTransform are stored in reversed row-column order, or (2) the row-column index is reversed somewhere during the computation of wxyz. Hope the above makes sense.

I am revising an application from using VTK 3.1 to 4.0 and I ran into an inconsistency in the result returned by vtkCamera::GetOrientationWXYZ. This is illustrated by the following C++ sample code: #include "vtkCamera.h" void main() { vtkCamera *cam = vtkCamera::New(); cam->SetPosition(40.5388, -58.1675, 36.4357); cam->SetFocalPoint(12.5875, 11.3799, 10.3485); cam->SetViewUp(-0.221512, 0.263181, 0.938972); cam->ComputeViewPlaneNormal(); // Needed for VTK 3.1 cam->OrthogonalizeViewUp(); float *wxyz = cam->GetOrientationWXYZ(); cout << wxyz[0] << " " << wxyz[1] << " " << wxyz[2] << " " << wxyz[3]; } When run using VTK 4.0 (nightly release, Oct 1, 2002), I get 284.514 0.937559 0.129517 0.322812 When run using VTK 3.1, I get 75.4863 0.937559 0.129517 0.322812 The first number (angle) differ in the two results. I think the number returned by VTK 4.0 is incorrect for the following reason. The method vtkCamera::GetOrientationXYZ() is used only in 2 classes, one of which is vtkVRMLExporter. In VTK3.1, vtkVRMLExporter generates a correct vrml file. In VTK4.0, vtkVRMLExporter does not generat a correct vrml file (the viewpoint is oriented in the wrong direction). Tracking the computation through the source code of VTK 3.1 versus 4.0, the main difference occurs in the row-column indexing of the matrix in the class vtkTransform. In particular, the method vtkTransform::GetOrientationWXYZ() is void vtkTransform::GetOrientationWXYZ(double wxyz[4]) { int i; this->Update(); // convenient access to matrix double (*matrix)[4] = this->Matrix->Element; double ortho[3][3]; for (i = 0; i < 3; i++) { ortho[0][i] = matrix[0][i]; ortho[1][i] = matrix[1][i]; ortho[2][i] = matrix[2][i]; } //...etc where ortho is subsequently used to compute w,x,y,z. If I transpose the ortho matrix, that is, change the above loop to for (i = 0; i < 3; i++) { ortho[i][0] = matrix[0][i]; ortho[i][1] = matrix[1][i]; ortho[i][2] = matrix[2][i]; } and rebuild VTK 4.0, then the above sample program gives the same result as that of VTK3.1. Also, the vrml file exported by vtkVRMLExporter is correct (viewpoint looks at the correct direction). The above suggests that either (1) the elements in the matrix of vtkTransform are stored in reversed row-column order, or (2) the row-column index is reversed somewhere during the computation of wxyz. Hope the above makes sense.

Message-ID: <28C3497E-D79F-11D6-8580-000393686412@chalkie.org.uk> Dear all, I'm trying to volume render a set of 20 z slices in tiff format in a=20 tk window using a python script modified from one found at atamai.org=20 (tkvolumelod.py) My data seems not to be read properly. The tiff=20 files are from a confocal microscope, and are a series of z slices=20 through a living cell. Data is from PC, but I am doing this on linux,=20 so I have to SetDataByteOrderToLittleEndian() right (see script=20 below)? The data should look like a hollow half sphere, but appears=20 as arrays of little rectangles, no matter how I adjust the opacity=20 and colour transfer functions in the script. My python script is below (modified from atamai.org so it reads tiff=20 files as a dataset) I am using vtkTIFFReader, and believe I am specifying the fileseries=20 as a 102x119x20 data set with 1x1x3 spacing. my command is like python volrendscript.py fileprefix my tiff files are named for instance fileprefix01.tif fileprefix02.tif etc . to fileprefix20.tif In gimp if I look at one of the tiff images in the middle of the=20 stack and do a histogram I can see that there a re pixels of all=20 values from 0 to 255. It seems like data is loaded and something is=20 displayed (no segmentation faults, or other errors at the command=20 prompt, and I can rotate it around and zoom just fine), but it looks=20 nothing like the images the rendered dataset is made from. The bottom=20 of the stack seems to be displayed with high values (in my case=20 green) and the higher slices are orange then red at the top. Seems=20 like the problem might lie here?

See the examples at http://public.kitware.com/VTK/doc/release/4.0/html/c2_vtk_e_2.html#c2_vtk_e_vtkTextMapper annotatePick.tcl does what you want, except it does so when the user presses 'p' instead of mouse-clicking.

I have a problem determining the coordinates of the points of each element

IIRC __del__ is actually called only after the window is killed and any "bad behaviour" can occur when the window is alive. Ok, there is the case that the window is dead and the actors are still alive. But are we guaranteed that __del__ will be called as soon as the window is destroyed? The order of destruction of the objects also matters here. I dont remember clearly but is there a way to always call a function *before* a widget (I mean any widget) is destroyed and not at object destruction? If the renderers maybe removed in that function. However, its been a while since I used wxPython so I cant remember the exact thing to do. Could any experienced wxPythoners comment on this? cheers, prabhu From fusion@thuule.pair.com Fri Oct 4 21:32:37 2002 From: fusion@thuule.pair.com (Alan McIntyre) Date: Fri, 04 Oct 2002 16:32:37 -0400 Subject: [vtkusers] vtkInteractorStyle References: <3D9DC5EB.30507@student.uni-magdeburg.de> Message-ID: <3D9DFAE5.7090707@thuule.pair.com> Steffen, The "void(*f)(void *)" parameter is a pointer to a C function that looks like this: void func(void *); How much that helps you out I don't know.

I think the '&' in the second example isn't necessary in the eyes of some (most?) compilers, but having it there doesn't do any harm as far as I know. The second example is the one you want in your particular case. As for passing a C++ class method in as the parameter to SetLeftButtonPressMethodArgDelete, I'm not exactly sure about the 'proper' way to do that, since it appears to be expecting a plain C function. What kind of compiler error are you getting? I don't have the VTK source on my machine here at home right now, so I'm kind of in the dark as to the usage/behavior of SetLeftButtonPressMethodArgDelete, but I'm wondering if the reason the it expects a pointer to a function with a void* parameter is so that class methods can be given to it. If I recall correctly, isn't the pointer to the object pushed onto the stack (kind of like an invisible first parameter) when calling class methods? If that's the case, perhaps the get_mousePos(void*) method in Steffen's example could be passed if it was declared like this: void get_MousePos(); Somebody please let me know if I'm totally clueless here; I don't want to give Steffen any bad info.

Steffen,

As far as passing function pointers goes, there is a difference
between this:

and this:
    obj->SetSomething(&my_function);
I receive an error during compiling saying that this is not a valid call
for a member-function.

obj->SetLeftButtonPressMethodArgDelete(&this->get_mousePos);

Shouldn't it just be

        "(this->get_mousePos)" ?

(Versus "(&this->get_mousePos)"
     or "(this->get_mousePos())" ).
You are right but this doesn't work either. I have programed a slice viewer object which
has a mapper, a render window and an interactor. Now, I'd like to define my own
vtkInteractorStyleUser. My source code is:

...
vtkRenderWindowInteractor *intAct = vtkRenderWindowInteractor::New();
vtkInteractorStyleUser *style = vtkInteractorStyleUser::New();
    style->SetLeftButtonPressMethodArgDelete(this->get_mousePos);
    intAct->SetInteractorStyle(style);
...

void SliceView::get_mousePos(void *)
{           
    ...
}

The error I get is:

coversion of parameter 1 from 'void (void *)' to 'void (__cdecl *) (void *)' is not possible

Dharmendra, Take a look at the vtkLODActor class: http://public.kitware.com/VTK/doc/nightly/html/classvtkLODActor.html It allows different levels of detail for interactive updates versus static display. The lower the level of detail, the faster the rendering.

It looks like you have built both Python and VTK with the static Tcl/Tk libraries. Maybe you should recompile both Python and VTK to use the shared versions of Tcl/Tk. For VTK make sure CMake is using the shared version. TCL_LIBRARY:FILEPATH=/usr/lib/libtcl8.3.so TK_LIBRARY:FILEPATH=/usr/lib/libtk8.3.so Or whatever appropriate version is on your system.

In one configuration a VTK = window is used to draw 2D text. When the text is displayed, it is drawn = as expected at the lower left corner of the screen. I have tried = various methods to set the origin to the top left for user convinience. = The only method I can find that works is SetPosition. To make this = effective I need to get the height of the text then use the window = height to calculate the offset. GetHeight returns 0.0 so that doesn't = work. The rest of the text in embedded in the code below. text_ =3D vtkActor2D::New(); vtk_renderer_->AddActor( text_ ); text_mapper_ =3D vtkTextMapper::New(); text_->SetMapper(text_mapper_); vtk_renderer_->AddActor(text_); =09 vtk_renderer_->SetBackground(0.0,0.0,0.0); text_mapper_->SetFontSize(12); text_mapper_->BoldOn(); If I use any of the next four lines the text does not show up at all text_mapper_->SetVerticalJustificationToTop(); text_mapper_->SetVerticalJustification(VTK_TEXT_TOP); text_mapper_->SetJustification(VTK_TEXT_CENTERED); text_mapper_->SetJustificationToCentered (); } text_mapper_->SetInput(str_ptr); the line belows always returns 0.0 float height =3D text_mapper_->GetHeight(this); The line below works but is not flexible enough to handle different = string lengths text_->SetPosition(10.0, 80.0); There is another GetHeight that from the description might work but it = requires the address of a vtkViewport. How do I get one of these?? Is there a more flexible way to get the text origin to be the top keft = corner of the window?? Did I use the set justification methods incorrectly?

Message-ID: <5.1.0.14.0.20021007130824.00ab8100@mail.viz-solutions.com> I just tracked down what looks like an odd bug, and I was wondering if anyone out there had any insight. I'm using a vtkPolyDataReader object to field incoming polydata definitions through a socket. I do this by reading the polydata from the socket into a string, then using the input string in the vtkDataReader. Everything generally worked fine, except in some cases the pipeline would not update when new data came down the socket. Eventually I tracked the problem down to vtkDataReader::SetInputString which, before assigning the string, does a string compare between the old and new string. When the new and old datasets were very similar (usually identical geometry, slightly changed scalar values) the strncmp would return a match. The string length was correct, and once the string compare was removed, everything worked fine. I'm working on a Windows 2000 machine with VC++ 6.0. I'm about to try the same thing on IRIX and Linux to see what happens, but I was wondering: 1. Has anyone seen this kind of behavior before? 2. Should the string compare really be there at all, given that these strings could be very long? Regards, Kevin.

I'm not sure what you are seeing is a bug per-se - does your Irix/Linux build do the same thing? I agree that the string compare could be expensive, but the dataset update could be even more so. I have been told that the data readers/writers are going to change in the near future to xml anyway, but it would be good to know if this is just a windows problem. I have been using the socketcommunicator for quite some time and it doesn't exhibit these symptoms.

I think its entirely possible that the vtk socket code does demonstrate the same symptoms. As I said, for some reason, it only happens when the incoming polydata only changes slightly from the version currently in the reader. It would be difficult to extract the code that I'm seeing this on, but perhaps I'll try to make a small sample that exhibits the same symptoms. As far as the cost of the string compare, it seems to me that by uploading the responsibility of that check to the caller of the reader, you give the programmer the option to either spend the time checking, or not. In my case, I'm performing that check already before sending the data down the socket, so its purely wasted time for me. Its a small point, but perhaps even a "no check" option would be a good addition to the reader. Thanks for the feedback Jeff.

Message-ID: Nothing to do with the possible bug, just something <=2c worth, To speed up the case where two very long strings are different can you first compare string lengths? Ie if the lengths are different the strings are different, which should save some time in that case. Where the lengths match then the full compare is needed. Another trick, which is no use as a general approach, but can be used in specific applications: If long strings typically carry a prefix which changes slowly, and a suffix which changes more rapidly, it can be much more efficient to do your own compare (when the lengths are equal) by comparing chars starting from the end and advancing towards the front of the string. regards Dave Pont |--------+---------------------------------> | | Kevin Wright | | | | | | Sent by: | | | vtkusers-admin@public.k| | | itware.com | | | | | | | | | 08/10/2002 10:32 | | | | |--------+---------------------------------> >------------------------------------------------------------------------------------------------------------| | | | To: vtkusers@public.kitware.com | | cc: | | Subject: Re: [vtkusers] string compare bug? | >------------------------------------------------------------------------------------------------------------| At 05:13 PM 10/7/2002 -0400, you wrote: >>>Are you using vtkSocketController/vtkSocketCommunicator?

I want to be able to get the point the glyph was constructed from as a result of a pick operation. I gather from the web page on Glyph3D that the "GeneratePointIds" option is desireable. A fragment of the Tcl code I have is: vtkUnstructuredGridReader ugr ugr SetFileName ptdata.vtk vtkConeSource cone vtkGlyph3D glyph glyph SetInput [ugr GetOutput] glyph SetSource [cone GetOutput] glyph GeneratePointIdsOn vtkPolyDataMapper glyphmapper vtkActor glyphActor proc endPick {args} { # What code here? } vtkCellPicker picker picker SetEndPickMethod endPick Two things are wrong here: 1) The bounding box is drawn around the whole collection of points, whereas I want to box just the glyph selected. 2) I can't seem to find a way to identify the original point from the glyph through any accessor methods. Can anyone tell me how to access the original point from within the endPick routine? The cell reported by the picker is one for the polygon of the cone. It seems to have only coincidental relationship to the original point. Can anyone tell me how to change the behavior of picking away from drawing the bounding box? If anybody cares, I've attached the point data file Lee A.

If the renderers maybe removed in that function. The runtime error R6025 is a specific Windows error. But it seems that on Linux, we sometimes obtain a core dump. Unfortunately, I can't certify the behaviour of events between the closing and the destruction in memory of the window. But the problem that we have appears after the window's destruction. I have discovered Python recently, and I don't know all mechanisms under this langage. But this destructor realize a clean destruction of the wxVTKRenderWindow instance. So, I think this destructor isn't bad, moreover it solves runtime error problems on windows and core dump problems on linux. But if these errors persist, I'm ready to search a best solution (when I'll know all specifications of garbage collector :) ).

Pardon me for lack of order in this file. I did this as test long time ago and I just attach it here to convey the idea.. First of all it is written for non MFC win32 application. In the WinMain there is a call to set up vtk (method : myVTKApp) Here I use directly vtk window. If you don't want this use SetParentId on the renderwindow and pass the window handle. Inside the myVTKApp there is a call to set the winproc (GetWindowLong). (I used two winprocs (1,2) to understand the behaviour , but you need only one winproc). Your mouse, key event arrives at the winproc and it could be either WM_CHAR or any other. So there you have the event and now you can do what you want with it. If you just want to pass it to vtk use vtkHandleMessage2 to pass it to vtk. With this you know exactly what interactions are happening and it is completely in your control.

If I had to guess, I would say that its a visual C++ bug, I just meant that the vtksocket code may exhibit the same problem when using vc++. I'm actually using the 4.0 release, the strncmp is on line 200 of that version. I just checked the nightlies, and it is on line 178 of that file. There are multiple versions of SetInputString, all of which end up calling the version with the string compare in it. I should have at least the LINUX version of this running today, so I'll know better then. Kevin.

Here is some python pseudo code: fa = vtkFloatArray() pnts = vtkPoints() # create your points. for i in range(pnts.GetNumberOfPoints()): pnt = pnts.GetPoint(0) scalar = function(pnt) # your function fa.InsertNextValue(scalar) Now you can use the vtkFloatArray to do what you want. For instance if the points are part of a vtkPolyData object you can do this: pd = vtkPolyData() pd.GetPointData().SetScalars(fa) cheers, prabhu From marcelo@radioimaging.net Tue Oct 8 18:05:50 2002 From: marcelo@radioimaging.net (Marcelo Costa Oliveira) Date: Tue, 8 Oct 2002 14:05:50 -0300 Subject: [vtkusers] keyboard events Message-ID: <00a601c26eec$f3fc2340$d4323690@System.local> This is a multi-part message in MIME format. ------=_NextPart_000_00A3_01C26ED3.CE937400 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Anybody has a example or know how class i use to rotate my volume using = keyboard arrows.

Suppose your vectors are in a dataset call ds. 1. Create a vtkFloatArray (one component) consisting of vector norm (scalar value) at each point. Suppose this array is called "norms". 2. Put this array into the data set as scalars. In C++, this would be ds->GetPointData()->SetScalars(norms); 3. Use vtkThresholdPoints to extract only those points having scalar value (vector norm) between the two desired values. Hope this helps.

I have written the same code in tcl and it works fine and so I think it is not a problem with hardware (I have a Matrox Millenium G400 graphic card).

I've got a weird display problem. The first time I try to render,
everything works fine. If I close the program and I try it a second
time, nothing is displayed anymore. After closing the render-window and
redrawing it, the rendering is again ok. The same story goes on and on.
The third time I start my program, only the third window will start
displaying something... the fourth time, the fourth window will start
displaying, .... After restarting X, the problem restarts with the first
window.
I also loose some memory during each cycle. It's freed with the restart
of X.

Some colleagues have encountered similar problems. OS is Linux Redhat
7.3 or 8.0 (same problem). Graphical board is a nVidia Gforce4/2 (with
dedicated drivers installed).

Does anyone recognize this problem? If yes, is there a solution? Any
suggestion will be appreciated.

Regards
Thomas

As far is I know, this is not The Right Way(tm) if you want to add functionality in a generic fashion. This would mean that your class can only work on OpenGL targets. A better way would be to derive from vtkActor and also CONTAIN an instance of vtkActor as member that can be used to perform rendering. The contained vtkActor will specialise (due to the object factories) as per usual. > Ron Jerome > Institute for Chemical Process and > Environmental Technology > National Research Council Canada > 613-993-5346 > > > >-----Original Message----- > >From: Steffen Oeltze [mailto:Steffen.Oeltze@Student.Uni-Magdeburg.DE] > >Sent: Wednesday, October 09, 2002 6:00 AM > >To: Vtkusers (E-mail) > >Subject: [vtkusers] deriving my own class from vtkActor > > > > > >Dear VTK-users, > > > >I have tried to derive my own class from vtkActor using the following > >code: > > > >class FIB_TRACK : public vtkActor > >{ > >public: > > FIB_TRACK(double [3], double [3], bool); > > ~FIB_TRACK(); > >.... > >} > > > >For creating a new object I use: > > > >FIB_TRACK *newAct = new FIB_TRACK(seedpoint, dims, true); > > > >Then, I construct the rendering pipeline, add the actor to the > >renderer and render the window but nothing happens.

I need to blank out a portion of my Structured Grid (consisting of Voxels ). I used the following functions in class vtkStructuredGrid ... structGrid->BlankingOn(); for(int i=start; iBlankPoint(i); ... but nothing seems to happen when the image is rendered. (1) The blanked out portions still appear in the image (2) also when I try to find out the neighbours of the cells just on the boundary of the blanked region, they still appear as neighbours even though the some of them happen to be in the blanked region. For example, if in the 2x2 grid below, the points a, b, c, d, e, f are blanked out. Then the neighbours of cell 13 should be 12, 20, 9 and Null. The cell 'd' should not show up as one of its neighbours. When an isosurface is rendered, the blanked out cells should not be considered while checking for isosurface cells, but this does not happen. 18 19 20 21 22 23 24 11 12 13 d e f 17 7 8 9 a b c 10 0 1 2 3 4 5 6 Does anybody know a way of doing this ? What am I missing here ? Has anyone run into this problem before? Any help will be deeply appreciated. Thank you in advance.

Every time I run a vtk program from the testing tree, the amount of free system memory (as reported by top) reduces by a certain amount (about 1 MB for Mace.cxx or Mace.tcl). This memory is persistently lost and can only be reclaimed by restarting the system. Am I mistaken, or have others experienced the same problems?

If I explicitly say points.GetPointData().GetScalars().SetName("elevation") it still writes out 'scalars' as the name. Now, if I set the scalar name explicitly with the writer, it writes out 'elevation'. ie out.SetScalarsName("elevation") To further complicate things, if I add more arrays of scalar data with GetPointData().AddArray(myArray) it does not append not merely append the extra arrays when I write the structuredpoints object to file. It mix and matched the arrays. In one instance, with the additional arrays, elevation was written second in the file and the name showed up....so it is there, something is just not allowing it to write the name to the file when it shows up first in the file. To clarify all of this, it would appear that StructuredPointsWriter uses a default name 'scalars' for the first scalar written to file, unless explicitly set within the writer object. With additional arrays, it does not just append them on to the original pointdata, but alters the order (how/why?). Am I doing something incorrectly? This all seems pretty straightforward. As reference I am using java + vtk 4.0. Any thoughts? -chris From cnavarro@ncsa.uiuc.edu Wed Oct 9 19:29:30 2002 From: cnavarro@ncsa.uiuc.edu (Christopher M.

The long answer is: In the old days (VTK 3.2 and earlier), the arrays/attributes did not have names. The names were stored in vtkFieldData instead. Furthermore, vtkPointData and vtkCellData were not subclasses of vtkFieldData, instead they each had an associated vtkFieldData. This meant that the only way to associate a name with an array was to store it in field data. This is why the writers had and still have special methods to set the attribute names stored in the file and also why they use a default name for each attribute. The new VTK readers/writers we are developing will not have this problem. They are currently in the development/testing stage and will be part of the next ParaView release (to be announced in a few weeks) and hopefully, the next VTK release. -Berk On Wed, 2002-10-09 at 14:04, Christopher M.

Thanks, Surajit Nundy From nundys@neuro.duke.edu Wed Oct 9 19:00:16 2002 From: nundys@neuro.duke.edu (Surajit Nundy) Date: Wed, 9 Oct 2002 14:00:16 -0400 Subject: [vtkusers] Memory leaks using VTK on OS X Message-ID: <9F946A00-DC05-11D6-97B7-000393B290A0@neuro.duke.edu> I thought that this was only a result of using Java-wrapped vtk but it persists with c++-vtk and tcl-vtk. Every time I run a vtk program from the testing tree, the amount of free system memory (as reported by top) reduces by a certain amount (about 1 MB for Mace.cxx or Mace.tcl). This memory is persistently lost and can only be reclaimed by restarting the system. Am I mistaken, or have others experienced the same problems?

In-Reply-To: <3DA42D0F.F4F2AA7E@esat.kuleuven.ac.be> References: <3DA42D0F.F4F2AA7E@esat.kuleuven.ac.be> Message-ID: <20021010071622.GA25292@carol.science.uva.nl> Hi Thomas, Although the symptoms you describe are not completely the same as what I have seen on some systems with the same configuration you are using, it's not that different. Here's what you should check; Take a look at /usr/include/GL/gl.h on your systems. If it mentions "Mesa" at the top, you are using the wrong include files. To fix that, run the following commands: ln -sf /usr/share/doc/NVIDIA_GLX-1.0/include/GL/gl.h /usr/include/GL ln -sf /usr/share/doc/NVIDIA_GLX-1.0/include/GL/glx.h /usr/include/GL ln -sf /usr/share/doc/NVIDIA_GLX-1.0/include/GL/glxtokens.h /usr/include/GL Then rebuild Vtk (or at least recompile and rebuild all Vtk libraries that depend on OpenGL). The problem is that the nVidia RPMs don't install the correct header files by default. -- Rob -- [] Robert Belleman X Section Computational Science [] [] robbel@science.uva.nl |X| University of Amsterdam, the Netherlands [] [] tel: (+31) 20 525 7510 X http://www.science.uva.nl/~robbel/ [] On Wed, Oct 09, 2002 at 03:20:15PM +0200, Thomas Koninckx Local wrote: > Hi, > > I've got a weird display problem.

The standard compiler on a SuSE 8.1 system is gcc 3.2 (AFAIK). This compiler is stricter that the "old" gcc 2.9.xy and compiler closer to the standards, as you can see in your mail. Your problem can be solved by type-casting the pointer (static_cast) char** to const char**.

I will answer to my own question :) I checked Suse web site, this Linux distrib comes with Tcl/Tk 8.4. CMake won't support it until you use the CVS version. As a matter of fact, you will have to use VTK CVS too. -- Sebastien Barre From james@rogue-research.com Thu Oct 10 13:58:36 2002 From: james@rogue-research.com (James Dessart) Date: Thu, 10 Oct 2002 08:58:36 -0400 (EDT) Subject: [vtkusers] building debug? Message-ID: Is there a way to build VTK with debugging symbols? I seem to be getting into an infinite loop, and I'm not sure what specific in VTK is causing it, so I'd like to examine it in more detail. Should I just add -g to the CFLAGS, or is there already a mechanism to build a debug version?

 Hi vtk Users,

 I have two questions:

 

1.      From cellLocator->IntersectWithLine I compute the intersection point and its cellID on the STL file. Now I want to find all the points within a radius around the intersection point. I tried using vtkPointLocator::FindPointsWithinRadius(radius, point, vtkIdList *result) But I was not successful with the following code:

                  float p1[] = {2.0, 1.0, 3.0};

float rad = 2.0;

vtkIdList *res;

// Build a locator

vtkPointLocator *pointLocator = vtkPointLocator::New();

pointLocator->SetDataSet(STLReader->GetOutput());

pointLocator->FindPointsWithinRadius(rad,p1,res);

pointLocator->BuildLocator();

 I dont know where I am goofing up the code. As soon as Execute I am getting error as Memory cant be assigned error I debugged the code it is stopping at  vtkIdList.h // Description:

// Reset to an empty state.

void Reset() {this->NumberOfIds = 0;};

*/

 

 

2.      Is there any vtk class, which I can use for collision avoidance? Basically I have two STL files and I want to check the collision around a particular point.

 

Any Help in this regard is very well appreciated.

 Best Regards

Siddu.

Rainer, if you are willing to experiment, we can try the following. Keep using VTK 4.0, and your current CMake (is it a release ?) and try any of those: a) edit the top VTK/CMakeList.txt file and add *at the top*: ADD_DEFINITIONS( -DUSE_NON_CONST -DUSE_COMPOSITELESS_PHOTO_PUT_BLOCK ) or the less intrusive b) Run your favorite CMake cache editor (i.e. CMakeSetup, or ccmake), show the advanced values, and add the above flags to any of those (if they exist): CMAKE_CXX_FLAGS CMAKE_C_FLAGS Thus, your CMAKE_CXX_FLAGS will probably look like: -g -O2 -DUSE_NON_CONST -DUSE_COMPOSITELESS_PHOTO_PUT_BLOCK Keep me posted if any of those work -- Sebastien Barre From eric@ece.gatech.edu Thu Oct 10 15:52:27 2002 From: eric@ece.gatech.edu (Eric Pichon) Date: Thu, 10 Oct 2002 10:52:27 -0400 (EDT) Subject: [vtkusers] small objects are not rendered Message-ID: Hi All, When trying to render many objects, VTK will discard those that are too small and too far (even though they are still much bigger than one pixel).

I'm working here in the Macromolecular Structure Group at UCSF (San Francisco) and I recently discovered MayaVI - Very nice program !! Since our data sets (optical and electronical microscopy data stacks) are rather "fuzzy" we would prefer volume rendering over surface rendering. 1) Are there new modules being implemented for mayavi ? Maybe "Volume Rendering" ;-) I read the documentation for mayavi and thought it shouldn't be that hard to convert e.g. the iso-surface module into a volume rendering module, since VTK supports both equally well, right? 2) I'm just curious how the "scalar cut plane" is implemented? Doesn't it convert the viewed data into a 2D-texture and is therefore an "identical" view of what a "standard" z-section view looks like (if the cut-plane is perpendicular to the z-axis, of course) ? 3) How do I change the used look-up table? I realized that a vtk-file contains a line that reads "LOOKUP_TABLE default" - what else is there besides "default" ? Also the mayavi example directory contains a ".lut" file - how do I use that? Thanks again for the nice work?

--=====================_2261802==.ALT-- From vtk_replies@yahoo.com Thu Oct 10 22:27:29 2002 From: vtk_replies@yahoo.com (vtk replies) Date: Thu, 10 Oct 2002 14:27:29 -0700 (PDT) Subject: [vtkusers] RE: deriving my own class from vtkActor In-Reply-To: <20021009162102.7595.70631.Mailman@public.kitware.com> Message-ID: <20021010212729.26224.qmail@web21510.mail.yahoo.com> Hi, I ran into a similar problems with deriving my own classes from vtk classes - it turned out that when I created my child class instance, the parent class variables were not intialized. These variables were used in some of the functions in the parent class that I wanted to use. Since I use vtk3.2, I dont know what are the variables in vtkActor class that need initialization in vtk4.0 [The following is an overkill, but it is just another way of doing things - (the disadvantages of doing it are having to re-run config , making changes to lib, and possible memory leaks - not sure - there are probably better ways- if at all nothing, someone will point to simpler way to you after seeing my elaborate mail :)) ). (1) put the additional function, eg., fun1() , that you wish to have in your derived class as a Virtual function in the vtkActor class. (2) then, define the fun1() in the derived class to do what you want it to do. (3) define the New() function in your derived class. (4) in your derived class constructor call the vtkActor() contstructor with appropriate values for intializing any variables in the class - this will properly instantiate any vtkActor class variables. (5) you probably already have a destructor for your derived class in place. (5) for destroying instances of your derived class, call the Delete() method ( since u created the derived class using the New() method in vtk). It should ( probably not cause any mem leaks :) ) call delete() of vtkActor class and then finally delete your class instance too. (6) in the Makefile.in of the appropriate directory, add vtkActor to the list of Abstract classes (7) add your derived class to the list of Concrete classes (8) SAVE all other files that you have changed and your own files to a different dir. (9) re-run config with your own options and make to integrate your class into the library. ] good luck ! cheers, Joseph. --- vtkusers-request@public.kitware.com wrote: > Send vtkusers mailing list submissions to > vtkusers@public.kitware.com > > To subscribe or unsubscribe via the World Wide Web, > visit > http://public.kitware.com/mailman/listinfo/vtkusers > or, via email, send a message with subject or body > 'help' to > vtkusers-request@public.kitware.com > > You can reach the person managing the list at > vtkusers-admin@public.kitware.com > > When replying, please edit your Subject line so it > is more specific > than "Re: Contents of vtkusers digest..." > > > Subject: RE: [vtkusers] deriving my own class from > vtkActor > From: "Charl P.

Basically, the rendering program has an input which changes over time, and that input is plugged into a vtkProgrammableGlyphFilter which is then plugged into a renderer. When I initialize the source, everything is fine and dandy, but when I add elements onto the source (with the same 'old' elements in the source), they don't get displayed. I suspect that this is something to do with an UpdateExtent not being right, although I lack experience in this area. Anyone have any ideas? Thanks in advance Nate From nsmith5@gl.umbc.edu Fri Oct 11 01:58:09 2002 From: nsmith5@gl.umbc.edu (Nathan Smith) Date: Thu, 10 Oct 2002 20:58:09 -0400 (EDT) Subject: [vtkusers] Problem with updating In-Reply-To: Message-ID: Lemme rephrase this because I narrowed down the problem: I do: set vtk(glypher) [vtkProgrammableGlyphFilter renderer] $vtk(glypher) SetGlyphMethod glypherProc After the data is updated, I checked vtk(glypher) right before any implicit calls to glypherProc, and it contained the right number of source points (7). But glypherProc is only called 4 times (the previous number of source points). So something between the renderwindow and renderer and glypherProc is not noticing that there is an updated source. Anyone know where this could lie?

(You may also need to do a STLReader->Update() before the call to BuildLocator.) For collision detection a thorough approach would be to tetrahedralize if necessary all your objects so they are represented as solids (not just as surface meshes) and then use vtkCellLocator::FindClosestPoint to detect if each point is inside a cell. Good luck, Tim. At 14:17 10/10/2002 +0100, Mysore Siddu wrote: > Hi vtk Users, > > I have two questions: > > > >1.

I hope that the result is explained by the examples that are available at http://www.civil.ist.utl.pt/~moitinho/vtk The behaviour of the object is controlled by two new Boolean variables ThreeGlyphs and Symmetric. When they are false the object behaves as vtkTensorGlyph. If ThreeGlyphs is true three glyphs, which are scaled according to the eigenvalue along the main axis (the one that after rotation corresponds to the eigenvector), are drawn. If Symmetric is true then the glyph (or the glyphs) is/are mirrored, i.e. 2 or 6 glyphs are produced. In the examples both variables are true. This behaviour is usefull in solid mechanics were other than knowing the direction and magnitude of the eigenvectors we also want to know its sign. Other uses are probably possible... I tried to write the code according to the instructions (a vtkMy...). Could someone who is interested in testing this provide me with some info on the best way to "publish" it?

I want to place these in "columns" along the left side of the view. I have coded something which should work, but although the vtkScalarBarActors show up when the window is initially rendered, as soon as a rotation is done, they disappear and vtk seems to be unstable from then on.

It seems to run on Windows' "MSDOS prompt" utility and you cannot retrieve previous commands (e.g. by using the up-arrow key) or edit the current command line. It is very difficult to even paste text from other windows (you have to move the mouse around to coax the text to come out of the clipboard), and as far as I know you cannot copy or cut text. These limitations do not exist if you run Tcl by itself (wish83); the shell that appears has all the basic text editing features. My question is: does anyone know how to run VTK from this nicer Tcl shell instead of the ugly MSDOS shell? Or is there some way to fix this behavior?

They almost work (I can see vtkRenderWindows and generate other classes easily). However, one major exception remains:- If I do vtkPolyDataMapper.SetInput( cone.GetOutput()), the program fails with a EXC_BAD_ACCESS error. This is not a java problem, because I cannot catch an exception around this code. Instead, a "Bus Error" happens with the above problem written to Console. Oddly, I can use vtkPolyDataMapper.SetInput in C++ and Tcl code without any problems, which suggests that the actual Java wrapping is responsible. Since this is a pretty important method and class (I can't visualize data without it), I was hoping you would have some ideas about it. I also haven't been able to use vtkPanel.java yet which apparently makes the Carbon drawing surface thread-safe (using vtkRenderWindow directly apparently is not thread-safe).

After playing with the actor's diffuse lighting coefficient, I concluded that lighting has no effect when color mapping is turned on. The specular coefficient does have an effect, however. After playing with the ambient coefficient I found out that the diffuse coefficient does have an effect, provided the ambient coefficient is non-zero. Similarly, the ambient lighting has no effect if the diffuse coefficient is zero. Since ambient and diffuse reflection are not linked when scalars are not used, why are they dependent on one another with scalars are turned on? Could this be a bug, or is this the intended functionality?

I am using the latest nightly build = (13-Oct-2002).

 

I seem to be unable to reconstruct a surface using = vtkSurfaceReconstructionFilter in C++ with the following code:

 

// Filled a vtkPolyData structure with points from
//$VTK_DATA_ROOT/Data/cactus.3337.pts.

      nPts =3D polyData->GetNumberOfPoints();

      // A nPts =3D 3337 = points

      = polyData->GetBounds(bounds);

 

      = polyData->Modified();

      surf->SetInput( polyData );

      = surf->Update();

      nPts =3D ((vtkDataSet * = )surf->GetOutput())->GetNumberOfPoints();

      // B nPts =3D 75760 = points

      ((vtkDataSet * )surf->GetOutput())->GetBounds(bounds);

 

      // Contour at 0 to extract the = surface.

      vtkContourFilter * cf =3D vtkContourFilter::New();

      cf->SetInput( (vtkDataSet * )surf->GetOutput());

      = cf->SetValue(0,0.0);

      cf->Update();

      nPts =3D cf->GetOutput()->GetNumberOfPoints();

      // C nPts =3D 0 = points

      = cf->GetOutput()->GetBounds(bounds);

 

      // Sometimes the contouring = algorithm can create a volume whose gradient

      // vector and ordering of = polygon (using the right hand rule) are

      // inconsistent. = vtkReverseSense cures this problem. 

      vtkReverseSense * rev =3D vtkReverseSense::New();

      = rev->SetInput(cf->GetOutput());

      = rev->ReverseCellsOn();

      = rev->ReverseNormalsOn();

      rev->Update();

 

      = polyData->DeepCopy(rev->GetOutput());

 

 

This is a translation of the TCL code in the example = reconstructSurface.tcl.

polyData is a vtkPolyData structure filled with = points from the file $VTK_DATA_ROOT/Data/cactus.3337.pts

nPts at point A has the value: 3337. At B, npts =3D = 75760, which is expected as the surface

has been constructed. However at C, nPts is zero and = the bounds all have VTK_LARGE_FLOAT in them!

The contour filter doesn’t seem to be producing = any output.

One oddity now is that I have had to put in the type conversion (vtkDataSet * ) = at the indicated points as a result of the VC7 compiler telling me: =

'vtkDataSetToPolyDataFilter::SetInput' : cannot convert parameter 1 from 'vtkImageData *' to 'vtkDataSet = *'

        = Types pointed to are unrelated; conversion requires reinterpret_cast, C-style = cast or function-style cast

 

I thought that vtkContourFilter takes any dataset = (and this is supported by the documentation).

This type conversion did not have to be specified in = the older nightly builds ( before August).

Another oddity is that the TCL example code works OK = ( I am using TCL8.4.0).

 

 

Can someone please help?

 

Thanks

Hence the compiler doesn't know it's a subclass of vtkDataSet. All the headers just state class vtkImageData; now so you need to add it. It's a pain, but it make the build process cleaner and faster (and it;s the right thing to do really) JB From rudi@yeah.co.at Mon Oct 14 19:42:53 2002 From: rudi@yeah.co.at (rudi@yeah.co.at) Date: Mon, 14 Oct 2002 20:42:53 +0200 Subject: [vtkusers] howto support a new file format Message-ID: <200210142042.53569.rudi@yeah.co.at> Hey out there! I want to implement a new reader of a non-commercial volume file format n= amed "f3d" and provide it as VTK class. I know the coding guideline and I am trying to do it all in VTK's types. But I am still missing some generic functions / templates / macros. So where do I find functions / macros / templates similar to these: #ifndef MAX #define MAX(a,b) (((a) > (b)) ? (a) : (b)) #endif #ifndef MIN #define MIN(a,b) (((a) < (b)) ? (a) : (b)) #endif #ifndef ABS #define ABS(a) (((a) > 0) ? (a) : -(a)) #endif // unit type enum UnitType{ f3dUum =3D 1,=09=09=09/* micrometers */ f3dUmm,=09=09=09/* millimeters */ f3dUm=09=09=09/* meters */ }; enum EndianType { =09f3dBigEndian =3D 1, =09f3dLittleEndian }; and conversion routines. I have all these but I want to replace it with vtk-proper functions.

Oh. Sorry, I only looked at the compile error. My first guess would be // Description: // If you want to contour by an arbitrary array, then set its name here. // By default this in NULL and the filter will use the active scalar array. vtkGetStringMacro(InputScalarsSelection); void SelectInputScalars(const char *fieldName) {this->SetInputScalarsSelection(fieldName);} Try setting the scalar name to something appropriate and see if that helps. Could be somehow you're getting a different scalar name in your data somehow (and the contour filter isn't using it).

Why is that and has something changed in the meanwhile concerning these restrictions ? I got curious because the AddRGBPoint(...)-method of the vtkColorTransferFunction allows the scalar value to be of data type float which makes no sense to me since the data values of the volume are required to be VTK_UNSIGNED_SHORT.

In-Reply-To: Message-ID: Paul and others, Thanks for your help. I just figured it out. I was using colored vtkLines, which looked fine in the VTK engine, but the vtkVRMLExporter was somehow not interested in their colors, so they were being written as black. I fixed it by wrapping tubes (vtkTubeFilter) around the lines. IMHO, Might be useful to fix the vtkVRMLExporter to preserve the color of lines. cheers, -Galen On Tue, 15 Oct 2002, Paul A Hsieh wrote: > > Hi Galen: I have used vtkVRMLExporter a bit and have been relatively > successfully in producing wrl files that look like what is displayed by the > vtk renderer.

It just shows the left-eye (or right-eye, I'm not sure...) picture all the time instead of swapping between the two eyes at 100Hz (display freq) RedBlue stereo is working properly by the way, but it doesn't look as nice :-( Are there any other settings? in vtk? in the display settings? in the OpenGL settings? Furthermore, I find the following piece of code quite peculiar (vtkOpenGLRenderWindow.cxx rev 1.63) void vtkOpenGLRenderWindow::StereoUpdate(void) { // if stereo is on and it wasn't before if (this->StereoRender && (!this->StereoStatus)) { switch (this->StereoType) { case VTK_STEREO_CRYSTAL_EYES: { } break; case VTK_STEREO_RED_BLUE: { this->StereoStatus = 1; } } } ..... Why is there an empty case for VTK_STEREO_CRYSTAL_EYES? Could this be why the stereorendering is not working? Thanks for any answers.

You need one entry point to your C++ code from Python. i.e. you need to hand off your ren_win to a C++ function in your C++ code where you are adding renderers etc. To do this you need to wrap atleast the one function that will be given a ren_win object. I'd suggest that you read up the documentation (Extending and Embedding the Python Interpreter) and also the Python C/API and wrap one single function that hooks into your C++ code. Expose this function to Python as a module. Lets call the file simple.c and the resulting python module simple with the single function static PyObject* simple_vtk_function(PyObject *obj, PyObject *args); or whatever. This function would in turn use the function I mentioned earlier to get the vtkRenderWindow from the argument passed to it. How to write the complete function is beyond the scope of this email. Its not that hard. Alternatively use SWIG (http://www.swig.org) or boost.python (http://www.boost.org)to do the job. Either way you'd have to pick something and figure out how to use it. I've attached an extremely simple example below of a simple function call in C that is called from Python. More on that follows. 2. Now from Python, import this module (simple) and then call your function with the ren_win. You should be all set. Anyway here is some actual working code that I wrote just for the purpose of illustration. This question has come up quite a few times. I thought I might as well write a small demo. It took less than half an hour. // --------------- cut here ---------- // simple.c #include "Python.h" #include "vtkPythonUtil.h" #include "vtkObject.h" #include "vtkObjectBase.h" #include extern "C" { PyObject* simple_vtk_function(PyObject *self, PyObject *args); } static PyObject* simple_vtk_function(PyObject *self, PyObject *args) { PyObject *vtkpy; if (!PyArg_ParseTuple(args, "O", &vtkpy)) return NULL; vtkObject *obj = (vtkObject*)vtkPythonGetPointerFromObject(vtkpy, "vtkObject"); /* Do what you want to do here. */ printf("%s\n", obj->GetClassName()); Py_INCREF(Py_None); return Py_None; } static PyMethodDef simple_methods[] = { {"vtk_function", simple_vtk_function, METH_VARARGS, "Simple VTK function"}, {NULL, NULL, 0, NULL} /* sentinel */ }; extern "C" { void initsimple(); } DL_EXPORT(void) initsimple() { PyObject *m, *d; m = Py_InitModule("simple", simple_methods); d = PyModule_GetDict(m); } // --------------- cut here ---------- Lets call this simple.c. Now compile it like so: $ g++ simple.c -shared -fPIC -I/usr/include/python2.1 \ -Ipath/to/your/vtk/headers -Lpath/to/your/vtk/libs/ \ -lvtkCommon -lvtkCommonPython -o simple.so Now run this from python: >>> import vtk >>> import simple >>> o = vtk.vtkRenderWindow() >>> simple.vtk_function (o) vtkXOpenGLRenderWindow It works! Anyway, I wonder why you are not using Python to do all the VTK related stuff and want to hand off everything to C++? Whats the point? VTK-Python is only a thin wrapper so should work ok. cheers, prabhu From blpriti@yahoo.com Wed Oct 16 10:45:09 2002 From: blpriti@yahoo.com (Priti Laxman) Date: Wed, 16 Oct 2002 02:45:09 -0700 (PDT) Subject: [vtkusers] Freezing VTK output window Message-ID: <20021016094509.21757.qmail@web80314.mail.yahoo.com> Hi, I am a novice in VTK.

Hi
I have just upgraded my OS, from Win98 to Win2000.
Nothing is working anymore. Is there a special setup to get the VTK4.0 running again?

PS: I already set TCLLIBPATH and VTK directory in the path.

Thanks for any help,

I realize that not many of will have had the funds to buy Quadro chipset based graphics cards, but for all you GeForce2 owners out there there's an interesting little hardware hack. It turns out that the GeForce2 and Quadro2 chips are really the same. The only difference on the graphics cards is a couple of resistors which are connected to different pins on the chip. With a little careful handywork it's possible to change your GeForce2 into a Quadro2, meaning you can do stereo rendering on Linux and get a better performing graphics card at the same time. I recently applied this hardware patch to my ASUS V7700 and it works beautifully with the ASUS 3D shutter glasses. For more information on this hardware hack, read http://www.tweakhardware.com/guide/quadro/ Let me stress again; I know this hack works on GeForce2 cards. I am quite sure it will *not* work on GeForce3 and GeForce4 cards. Also; don't blaim me if you try this hack and it fails in any way. Now back to Jorrit's Windows question; the thing I do in Vtk to render in stereo is the following: vtkRenderWindow renWin renWin StereoCapableWindowOn renWin SetStereoTypeToCrystalEyes renWin AddRenderer renderer With Vtk's RenderWindowInteractor, pressing '3' will toggle stereo on/off, otherwise call StereoRenderOn()/Off() like you do. I'm not sure why you would need the StereoUpdate(). I agree that the empty case in the switch statement you mentioned is puzzling, though I don't think it's the reason why stereo isn't working for you.

It's quite simple and works beautifully. There is a little tweak program that converts your GeForce into a Quadro card, called rivatuner. It works for drivers 28.32 and lower. (search google for "detonator version 28.32 download") The Stereo3D drivers from nvidia's website are NOT needed. Good sites with info are: http://www.stereofoto.de/java/browsers/pageflip.html http://www.nvworld.ru/index_e.shtml It might not be really legal to uses this patch, but hey, if you pay a good amount of money for your graphics card you might expect it to support stereo rendering, don't you think?

Yes, it's possible, the VTK doxygen stuff already creates what is called a "tag" file that enables you to link two documentations.

I am currently trying to use a custom renderer that has an aspect ratio that is often very different from the image dimension ratios. The renderer returns an appropriate aspect in its GetAspect method, but the camera is ignoring it. Could someone PLEASE change the vtkOpenGLCamera::Render method back so that it no longer trashes the correct aspect ratio. -Ken **** Kenneth Moreland *** Sandia National Laboratories *********** *** *** *** email: kmorel@sandia.gov ** *** ** phone: (505) 844-8919 *** fax: (505) 844-9297 ------_=_NextPart_000_01C27541.E1698C30 Content-Type: application/ms-tnef Content-Transfer-Encoding: base64 eJ8+IjcSAQaQCAAEAAAAAAABAAEAAQeQBgAIAAAA5AQAAAAAAADoAAEIgAcAGAAAAElQTS5NaWNy b3NvZnQgTWFpbC5Ob3RlADEIAQWAAwAOAAAA0gcKABAADAAcADUAAwBTAQEggAMADgAAANIHCgAQ AAwAHAA1AAMAUwEBCYABACEAAAA1QzJCQTA0MkNFNTQxNjRGOUIyMEY3OUY3RUM2RDU0RABUBwEE gAEAJQAAAFBsZWFzZSBmaXggdGhpcyB2dGtPcGVuR0xDYW1lcmEgYnVnLgAIDQENgAQAAgAAAAIA AgABA5AGACwIAAAuAAAAAwAJWQEAAAACAXEAAQAAABYAAAABwnVB8aGlmQ7gCzBNcryL33cr4wbM AAADAN4/r28AAAMAW4AIIAYAAAAAAMAAAAAAAABGAAAAAFKFAAB9bgEAHgBcgAggBgAAAAAAwAAA AAAAAEYAAAAAVIUAAAEAAAAEAAAAOS4wAAsAgIAIIAYAAAAAAMAAAAAAAABGAAAAAAaFAAAAAAAA AwAOgAggBgAAAAAAwAAAAAAAAEYAAAAAAYUAAAAAAAALABCACCAGAAAAAADAAAAAAAAARgAAAAAD hQAAAAAAAAsAEYAIIAYAAAAAAMAAAAAAAABGAAAAAA6FAAAAAAAAAwA3gAggBgAAAAAAwAAAAAAA AEYAAAAAEIUAAAAAAAADADiACCAGAAAAAADAAAAAAAAARgAAAAARhQAAAAAAAAMAPoAIIAYAAAAA AMAAAAAAAABGAAAAABiFAAAAAAAAAgEJEAEAAABKAwAARgMAAJ8FAABMWkZ1h0pRbwMACgByY3Bn MTI14jIDQ3RleAVBAQMB9/8KgAKkA+QHEwKAD/MAUARWPwhVB7IRJQ5RAwECAGNo4QrAc2V0MgYA BsMRJfYzBEYTtzASLBEzCO8J97Y7GB8OMDURIgxgYwBQcwsJAWQzNhZQC6YQwGOFBaFkC4BnIHRv HYA0aGUSIFYF8BewZyxSIAIgIEoAcHUKwHlYIDI0HnAB0DAUQEvXCfAF0ArAdAuAIBPRHWA5CYAg YR4wC4Ad4HZ0CGtPcAnwR0xDYX0HgHIhAANSCqIKhAqAIAsjcQDAdAUQeC0+RMUJ4HAIUHB5KB3A BABVJBBHFCBQBJBzIbBjcSBAdmVUIkAAgAIQcgZtIBAj0igxLjAqQmElg1swXS8nRTF8XSwjGCkf Ki8rPyNwLeAxLDEpKRkwIskdkF8ivyPPJN8l7ybzdQCQevhlL3YyYih/NA81HyuvtSy9VC/hIAER MLRsHyCLHcADYHcEIGF3YTkizx3gJ0QgcANwcHUOsCDg9mI55BggbgSBEoEAcCDg6xggC1FjB5Fp BUAD8B3AlSDxYiJAcz1xcHADYLZ4B3Au0GkekT1DcC8ApTkAIDJicy4ugEkg8O5tIHAIcDuxdDkS HxAdVfcyUDohQGFzHZBAUDu3HcD9LtAgE+A5kQOgOkUiQD6h+0MEOFFvAYAf4TDwHxEdQP84kUCi ImMdsz5xIMBFwQeAfwCBHpFEQz/iODA7mRggdP8IcAYxQ6I+Ij4wBzAOsDo27yBRPRAEIDAxQTpU B4AdwNsEcB5wYjrwHbNjIhQ4UbhpZ24FsB1SPRAuLcrVCFFsIOBzA3BlAiAd4MBQTEVBU0UgdR2z 8SF9OjpSO8NMRTswAND+a0/BRJUFQE4QHjEgsULx/z3CB5FNEwWwGCA6gUPaTqv2LR/RLc0qWQE1 9B/RIUD9PWFNBbA5ADxBLihZFwYRmx1AIQBOPpMHQCBMAaD/BbAu0E4hB5AtxFkCXfUugDddl1sz WRNlAMADEDogJmsEYFpBQHNb4y5n3G92XZZbJVkicEyAIUABYEAoNTA1KSA4gDQ0LTg5MTlar3Eu gGZheGBALoBjGDkoMjk3LcR9ZuAAAB4AcAABAAAAJQAAAFBsZWFzZSBmaXggdGhpcyB2dGtPcGVu R0xDYW1lcmEgYnVnLgAAAAALAAIAAQAAAAMA/T/kBAAAQAA5ADCMaeFBdcIBAwDxPwkEAAAeADFA AQAAAAcAAABLTU9SRUwAAAMAGkAAAAAAHgAwQAEAAAAHAAAAS01PUkVMAAADABlAAAAAAAMAJgAA AAAAAwA2AAAAAAALAPIQAQAAAAMAgBD/////AgFHAAEAAAAwAAAAYz1VUzthPSA7cD1TTkw7bD1F UzA0U05MTlQtMDIxMDE2MTgyODUzWi01Mzg3MzgAAgH5PwEAAABEAAAAAAAAANynQMjAQhAatLkI ACsv4YIBAAAAAAAAAC9PPVNOTC9PVT1TRUVNUy9DTj1SRUNJUElFTlRTL0NOPUtNT1JFTAAeAPg/ AQAAABIAAABNb3JlbGFuZCwgS2VubmV0aAAAAB4AOEABAAAABwAAAEtNT1JFTAAAAgH7PwEAAABE AAAAAAAAANynQMjAQhAatLkIACsv4YIBAAAAAAAAAC9PPVNOTC9PVT1TRUVNUy9DTj1SRUNJUElF TlRTL0NOPUtNT1JFTAAeAPo/AQAAABIAAABNb3JlbGFuZCwgS2VubmV0aAAAAB4AOUABAAAABwAA AEtNT1JFTAAAQAAHMFCHYuFBdcIBQAAIMOxZj+FBdcIBHgA9AAEAAAABAAAAAAAAAB4AHQ4BAAAA JQAAAFBsZWFzZSBmaXggdGhpcyB2dGtPcGVuR0xDYW1lcmEgYnVnLgAAAAAeADUQAQAAADMAAAA8 QjUxRjBDNjM2RTU3OEE0RTgzMkQzOTU4NjkwQ0Q3M0VEMjBENTFAZXMwNHNubG50PgAACwApAAAA AAALACMAAAAAAAMABhAQOMrQAwAHEAEDAAADABAQAAAAAAMAERAAAAAAHgAIEAEAAABlAAAAQUND T1JESU5HVE9USEVDVlNMT0csT05KQU5VQVJZMjQsMjAwMktFTk1BUlRJTkNIQU5HRURBTElORVZU S09QRU5HTENBTUVSQUZST01NQVRSSVgtREVFUENPUFkoVEhJUy1HRQAAAAACAX8AAQAAADMAAAA8 QjUxRjBDNjM2RTU3OEE0RTgzMkQzOTU4NjkwQ0Q3M0VEMjBENTFAZXMwNHNubG50PgAAg+0= ------_=_NextPart_000_01C27541.E1698C30-- From prabhu@aero.iitm.ernet.in Wed Oct 16 19:31:12 2002 From: prabhu@aero.iitm.ernet.in (Prabhu Ramachandran) Date: Thu, 17 Oct 2002 00:01:12 +0530 Subject: [vtkusers] (no subject) In-Reply-To: References: <20021016104017.26039.42965.Mailman@public.kitware.com> Message-ID: <15789.45168.864699.727899@monster.linux.in> >>>>> "VS" == vidya sivakumar writes: VS> Hi All, Is there any method to display coordinate axis in vtk? vtkCubeAxesActor2D, vtkAxes. prabhu From a.maclean@acfr.usyd.edu.au Thu Oct 17 00:22:32 2002 From: a.maclean@acfr.usyd.edu.au (Andrew J.

Oh. Sorry, I only looked at the compile error. My first guess would be // Description: // If you want to contour by an arbitrary array, then set its name here. // By default this in NULL and the filter will use the active scalar array. vtkGetStringMacro(InputScalarsSelection); void SelectInputScalars(const char *fieldName) {this->SetInputScalarsSelection(fieldName);} Try setting the scalar name to something appropriate and see if that helps. Could be somehow you're getting a different scalar name in your data somehow (and the contour filter isn't using it).

Secondly if you are using GUI if possible don't mix awt and swing components. AWT components being heavy weight will ALWAYS dominate the swing items. Ex: if you have a jpopup over a awt canvas, canvas will block the jpopup. Basically your popup will be hidden behind the canvas.... Sun says you can mix awt and swing, but there are lot of hassles (events are another nightmare when you mix....)

On the other hand if you had two winprocs one for the vtk window and one for the rest then it would go to the appropriate winprocs. If you don't give two then all will go through one. Second thing to check is the question of window handle. If do setParentId(hwnd) in vtk and not setWindowId(hwnd).Normally if the window handle is set properly then you don't need two winprocs. Lastly there is a tool that comes with visual studio called spy++ keep this running while you are running your application, then you can see on this spy window the origin of your events and exactly which window gets this event etc. Let me know if you need more help / tests....

Error E2034=20 C:\PROGRA~1\vtk40\lib2\vtk\Common\vtkCommonTCLInit.cxx 381: Cannot = convert 'int=20 (*)(void *,Tcl_Interp *,int,char * *)' to 'int (*)(void=20 *,Tcl_Interp
 *,int,const char * *)' in function=20 Vtkcommontcl_Init(Tcl_Interp *)

Error E2342 = C:\PROGRA~1\vtk40\lib2\vtk\Common\vtkCommonTCLInit.cxx 381:=20 Type mismatch in parameter 'proc' (wanted 'int (*)(void *,Tcl_Interp = *,int,const=20 char * *)', got 'int (*)(void *,Tcl_Interp *,int,char * *)') in function = Vtkcommontcl_Init(Tcl_Interp *)
 
I don't want to start editing files in case I end up with a build = that just=20 doesn't work.
 
My current setup is:
Windows 2000 with the Borland 5.2 compiler
 
I am quite a newbie, so any help would be greatly = appreciated.
 
Thanks in advance,
Stephen

However, PowerPlant ALSO uses the window's refcon to store its object associated with the window. So it doesn't make any sense for both to use it, since it's only a single variable. Here's my proposed change, which I will use in my own copy of the code, and which may be useful for anyone trying to use VTK in conjunction with PowerPlant and CodeWarrior. I have added a define of VTK_USE_PP, which should only be defined if VTK_USE_CARBON is valid. It also means the CarbonRenderWindowInteractor would be useless, but I'll come up with a PowerPlant interactor, if I can get the rendering working properly. Anyways, if VTK_USE_PP is defined, the refcon will not be set by the RenderWindow. Not sure if this works fully yet, but I'll keep you guys posted. If anyone has feedback on this, or is interested in knowing what it takes to get VTK compiling in CodeWarrior for Mac OS X, just ask.

This works fine except the order of the points list will be different from the order of the points in the OBJ file... if there are scalars associated with the points in the file they wont be assigned correctly. I've been meaning to write another obj reader that would preserve the list order... sometime.

The time steps come in as a discrete series of vrml scenes which I have imported into vtk as a list of ActorCollections, one ActorCollection per scene. My initial thought was to assign a slider to select a specific ActorCollection and set the rest of the actors opacity to zero.

Surely it would be sufficient to read the points into vtkPoints, polys into vtkCellArray, normals and tCoords into vtkFloatArray, and then just say output = vtkPolyData() output.SetPoints(points) output.SetPolys(polys) output.GetPointData().SetNormals(normals) output.GetPointData().SetTCoords(tCoords) Instead, vtkOBJReader reads the points, normals and tCoords, then it reads the polygons, and in this process it changes all the point IDs and duplicates most of the points. I can't figure out why this is even necessary.

That is, I want to have a vtkRenderWindowInteractor *and*, separately, a Tk root window both active, in the same process. The problem with doing this in Python is that (as far as I know) you are forced to call both vtkRenderWindowInteractor.Start() and Tkinter.Tk.mainloop() -- and either one prevents the Python interpreter from executing any subsequent lines in the .py file. I've tried spinning threads, but the vtkRenderWindowInteractor seems to starve all other threads. I am trying to avoid vtkTkRenderWidget. It dumps core on a lot of systems (when using Python, and I've tried the tricks -- setting VTK_TK_WIDGET_PATH, copying vtkTkRenderWidget into /usr/lib, configuring --with-shared).

Message-ID: I've managed to get a small demo going, using VTK within a PowerPlant view. The performance isn't what I'd like, but it was a proof of concept. If anyone is interested in my changes, mail me off-list, and I can walk you through the process. Note, because of the quick nature of the "port" I did, freetype isn't included in the build, and neither are the PNG classes. Some minor code changes were required to get it to compile, and finally run. They're fairly straightforward. My project takes under a half hour to compile and link, so in some sense, it has a leg up over the CMake solution, which, on the same machine, takes at least an hour.

Message-ID: <20021018152741.GD7467@mcs.anl.gov> Hello, I'm using VTK4.0, so if some of these things have been addressed in 4.1, please forgive me. I'm using vtkTensorGlyph with a vtkAxes as the source (with symmetry turned on), and I've run into a few problems. First, the output of vtkTensorGlyph eventually is run through vtkPolyDataNormals (the glyph is often a sphere or cone, and the output may be clipped, capped and triangulated, and I have to use vtkPolyDataNormals to avoid some strange lighting effects at sharp corners). When I'm using vtkAxes as the glyph, however, vtkPolyDataNormals panics because there are neither polys nor strips in its input. It would be much more convenient if it would just pass the data through in this case (perhaps with a warning), rather than give up completely. I can fix this myself without changing the library by deriving a new class from vtkPolyDataNormals, so that's not such a big deal. Second, vtkTensorGlyph::SetScaling() and family has no effect. Finally, when using vtkAxes as a glyph, I've noticed that sometimes the lines are the correct color, and sometimes they're black. It seems to depend on the camera's orientation. I would like the lines to have the same color regardless of what direction I'm looking at them from. Is there a way to do this? This is the most pressing issue for me.

If you use axes then you are not suposed to create the normals for the point data. In that case the code will not try to use them. If you create the normals, but they are not defined then you have a problem. > Second, vtkTensorGlyph::SetScaling() and family has no effect. > > Finally, when using vtkAxes as a glyph, I've noticed that sometimes the > lines are the correct color, and sometimes they're black.

Dear VTK-users,

I have derived my own class from vtkActor and I have added a couple of

After creating and modifying such a new actor I add it to my existing

vtkRenderer->GetActors() to retrieve my custom actors. Then, I would

get the error:

I guess this is a problem of backward compatibility but I don't know how

I think this would be a good way to introduce Cocoa developers to VTK and help both groups of developers. I don't want to step on any toes, so I want to give VTK developers a chance to voice their displeasure, should there be any. I also would like to ask if there is anyone else on the list who is utilizing VTK directly in Cocoa apps, and if so, how they have approached it. In this regard, I found certain problems with interactors in the Cocoa implementation which required fixes in the form of subclassing some of the the VTK-Cocoa classes and overriding mouse event methods. I also found that a standalone VTK view class could be created, which doesn't require the Cocoa developer to explicitly type their windows as vtkCocoaWindows. I was wondering how other Cocoa developers have dealt with these and other Cocoa-related issues. Drew ======================================== Dr. Drew McCormack (Kmr. R153) Afd.

If you added the vtkTypeMacro to your class' header, you
can use SafeDownCast. This is much safer down static casting:

vtkActorCollection *actors = vtkRenderer->GetActors() ;
vtkActor *actor;

for (actors->InitTraversal();actor=actors->GetNextActor());)
    {
    vtkMyActor* myactor = vtkMyActor::SafeDownCast(actor);
    if (myactor)
        {
        actor->MyExtendedMethod();
        }
    // etc etc
    }

Thank's a lot. How do I add the vtkTypeMacro to my class' header ?

Hi Steffen

Try casting to your type of actor - the actor collection contains pointers
to type vtkActor.

Unfortunately, I'm not very familiar with C. How does casting work ? 
What is the syntax ?

Subject: [vtkusers] deriving my own class from vtkActor


Dear VTK-users,

I have derived my own class from vtkActor and I have added a couple of
methods to this new class.
After creating and modifying such a new actor I add it to my existing
renderer. At some point I use
vtkRenderer->GetActors() to retrieve my custom actors. Then, I would
like to traverse the returned
list and apply a custom method to each of my selfmade actors. However, I
get the error:

'method' : is not an element of 'vtkActor'

I guess this is a problem of backward compatibility but I don't know how
to solve it. Can anybody help me ?

Steffen

Multiply that into 1024 users (very likely a low estimate) and you just generated 40MB of internet traffic! Wow!!

Anyway, recently the CVS tree has been modified in order to reduce the time taken to compile VTK (a very noble goal!:). So for each and every class that you use directly or indirectly, you need to explicity include the right header files. So in your case consider adding the following lines to your code. #include "vtkPolyData.h" #include "vtkRenderer.h" #include "vtkActor.h" Since in your case you are compiling the VTK tests it looks like you picked a bad day to download the RPM. Just check out the VTK dashboard (link on site) before you download a nightly release. Try a more recent (or an older one). cheers, prabhu -- It was so of old, Atula. It is not just so today.

Suppose I have a two-dimensional binary image, in which there is a donut-like object. If I use marching square to extract the shape boundary, I should get two circles (the inner and outer boundaries of the donut-like object). I find that in the output file (vtk Poly Data file) of the vtk marching square filter, the Cells Part are only line cells---no polygons. In fact, what I am most interested in is the connectivity lists of the points on these two boundaries, so I have to generate these two point-lists (a point-list here represents one circular boundary) by myself. 1) Can anyone tell me whether VTK marching square provides such functionality? 2) Suppose I have to generate such lists by myself strictly according to the point connectivity indirectly given to me in the Line Cells Part of the vtk Poly Data file, or suppose vtk can do this, my next question is: suppose that in the binary image I traverse the calculated point list representing the outer circle and that I look at my right hand side and I always see "black", if I do the same thing on the second point list representing the inner circle, will I always see "black" if look at my right hand side?

So the following code works OK. polyData->Modified(); surf->SetInput( polyData ); // Contour at 0 to extract the surface. vtkContourFilter * cf = vtkContourFilter::New(); cf->SetInput( surf->GetOutput() ); cf->SetValue(0,0.0); // Sometimes the contouring algorithm can create a volume whose gradient // vector and ordering of polygon (using the right hand rule) are // inconsistent. vtkReverseSense cures this problem. vtkReverseSense * rev = vtkReverseSense::New(); rev->SetInput(cf->GetOutput()); rev->ReverseCellsOn(); rev->ReverseNormalsOn(); rev->Update(); //polyData->Reset(); polyData->Initialize(); polyData->DeepCopy(rev->GetOutput());Andrew ___________________________________________ Andrew J.

Oh. Sorry, I only looked at the compile error. My first guess would be // Description: // If you want to contour by an arbitrary array, then set its name here. // By default this in NULL and the filter will use the active scalar array. vtkGetStringMacro(InputScalarsSelection); void SelectInputScalars(const char *fieldName) {this->SetInputScalarsSelection(fieldName);} Try setting the scalar name to something appropriate and see if that helps. Could be somehow you're getting a different scalar name in your data somehow (and the contour filter isn't using it).

Unix linkers perform only a single pass, so you want the libraries to be in the order of using as many symbols as possible, to least number of symbols. For example, vtkGraphics should come before vtkCommon. With shared libraries, you always get the entire library so order is not a problem. With static libraries, you only get what you need. If you use cmake for your project, the library ordering is maintained by cmake, and should work for both shared and static builds. -Bill At 01:47 PM 10/21/2002 -0700, Thomas Deschamps wrote: >Dear VTK users, > >I have some problems using the static libraries produces by the compilation of the sources of VTk on 2 different platforms: >1) Linux RedHat 7.2 >2) SunOs 5.7 > >My version of VTK is downloaded from the CVS repository. > >In both cases, the linking against these libraries is not working.

Yes, but the vtk*Python.exe does not specify which version of Python, Tcl/Tk etc. it requires. So its unlikely people will download it without knowing what it requires. Also, where does it install VTK-Python? Can someone who uses/builds these please clarify? Actually, if you want you can easily build a distutils based exe file for VTK-Python. Do this on a windows machine with Python installed: $ cd Wrapping/Python $ python setup.py bdist_wininst That should do the trick and build a distutils based exe that will install VTK-Python correctly with all the Python files and the DLLs on Windows if Python is already installed.

Okay this could be another one of java class path and putting the dlls /sos in the right place.

This requires a bit more information about your platform, and about your setup. Where your

*.java files are, where the vtk libraries are etc etc.......

Also this issue has been posted many times in the user group, so it might be quicker for you if you could

Find all the posting related to this in the archives and try the suggestions, if nothing works post again with

Details and what you have already tried.

I am just experimenting with picking and I am unsure how to efficiently work out which atom was picked. I am working in Python. I can identify the picked property (Actor) using picker.GetPath().GetFirstNode(), by I am not sure of the best way to find out which atom in my model was picked. Is there a user data component of an actor I could set when it is created and access to indicate what it represents when it is picked? I notice the document to SetPickMethod for a property indicates that a function and an argument can be stored for each actor, this would enable me to use the argument as a way to work back from the actor to the originating object. However, it seems that in the python binding SetPickMethod only takes a single argument (the method itself). As far as I can see I would otherwise need to implement some look up process ( e.g. keep a dictionary relating each actor address to the chemical object that it relates to), but for a very long list of actors this seems rather inelegant and maybe slow. Also, is there any way to pick multiple actors using something like the rubberband selection tools many programs use these days? Is there another way? thanks Paul Sherwood From prabhu@aero.iitm.ernet.in Wed Oct 23 18:07:36 2002 From: prabhu@aero.iitm.ernet.in (Prabhu Ramachandran) Date: Wed, 23 Oct 2002 22:37:36 +0530 Subject: [vtkusers] Picking questions In-Reply-To: References: Message-ID: <15798.55128.507845.745479@monster.linux.in> hi, >>>>> "PS" == P Sherwood writes: PS> I am just experimenting with picking and I am unsure how to PS> efficiently work out which atom was picked.

If you are using VTK 4.0+ then you can use observers to do this easily.

Why not simply a.AddObserver('PickEvent', self.mypick) Afterall your class will have all the necessary data? self.mypick is a bound function also classifies as a function.

Here's how to do that: in this case the scalars are floating point numbers, stored in the array eff_rad. vtkFloatArray* scalars = vtkFloatArray::New(); scalars->SetNumberOfValues(data_size); for (int i=0; iSetValue(i, eff_rad[i]); once you get your scalars in such shape, do this: say your polydata is called p_data. p_data->SetScalars(scalars); I needed to do that for this visualization I was doing. I wanted to warp a plane using one set of scalars and color it using another set of scalars, so I did what I just told you on the output of vtkWarpScalars, which is polydata. That changed the colors quite nicely. -- Gala On Wednesday, October 23, 2002, at 01:16 PM, Stefan Ulbrich wrote: > hello, > > how can I associate a scalar array with a polydata so that I can use > scalars to be mapped as colors? > > thanx > > stefan > > > _______________________________________________ > This is the private VTK discussion list.

Please add -lvtkFiltering to the link list, as vtkPolyDataSource is part of this kit. Somehow, I forgot this in the example Makefile and somehow it still works on other non-Irix platforms. I'll update the Makefile and make a new package available.

I think this should of course derive some vtk classes (e.g. vtkVolumeTextureMapper2D etc.) to use the features of GeForce3 (e.g. register combiners, multitexture mapping, etc.) to improve rendering performance. Has anyone completed similar vtk classes using texture mapping based on GeForce or give me any ideas how to realize this class? Thank you in advance.

The depth of the image from the VolPro card is probably a fixed depth of 0. The lines that pass behind the z = 0 plane are not drawn. I wish to draw them as if to an overlay plane, i.e. force them to be drawn in front. Does anyone have a way of doing this without having to grab each end point and the camera parameters, and then project onto the near plane and render as 2D actors each time the camera is altered? Perhaps there is way to directly send openGl drawing instructions to the window so that the lines are drawn after everthing else. Thanks for any suggestions.

I dont know of a way to do exactly this but take a look at the vtkSelectPolyData class. It lets you define a loop on your PolyData and then lets you select everything within or outside that loop.

I get streaks of reversed normals (appearing black) across the surface in places where there is no inconsistency, since the consistency is propagated out using a wave algorithm, in the order that the polygons are stored. I can get around the problem by simply turning ConsistencyOff(). Is there any need for a different normals algorithm that decides whether to enforce consistency based on some measure of how parallel the neighbouring polygons are? ie. if two neighbouring polys lie in the same plane then consistency is enforced more readily than if they make a sharp angle.

Can't find it. That one is a gcc3-only symbol. It's called by the dylib initialization routines, to work around a bug that Apple is aware of. For the time being, you can either compile with gcc 3, or change your make files to not use the initialization routines, and comment them out. I haven't tried a build since that change was introduced, however.

1. Why vtkPolyDataNormals is not working?

Can someone throw light on this

Here is the code I am working on:

vtkGeometryFilter *geoms = vtkGeometryFilter::New();

geoms->SetInput(Polydata output);

geoms->Update();

vtkDelaunay2D *Ttriangulate =vtkDelaunay2D::New();

Ttriangulate->BoundingTriangulationOff();

Ttriangulate->SetTolerance(stltolerance);

Ttriangulate->SetAlpha(0.01);

Ttriangulate->ReleaseDataFlagOn();

Ttriangulate->SetInput(geoms->GetOutput());

Ttriangulate->Update();

vtkPolyDataNormals *Snormals=vtkPolyDataNormals::New();

Snormals->SetInput(Ttriangulate->GetOutput());

Snormals-> SetFeatureAngle(30.0);

Snormals->SetComputePointNormals(1);

Snormals->SplittingOff();

Snormals->ConsistencyOn();

Snormals->Update();

float *n = Snormals->GetOutput()->GetPointData()->GetNormals()->GetNormal(ptId);

TCL) Message-ID: <15800.7351.929000.623242@gargle.gargle.HOWL> Hello dear VTK mailing list readers ! I have a C++ class library (already using some VTK objects like "vtkImageData" in its interface) that I want to make usable from within VTK/TCL or VTK/Python etc. scripts. This library however uses standard C++ exceptions for error reporting to its users and things like std::string to pass strings in and out. There is a hierarchy of C++ classes that could be thrown in the case of some error condition. I probably have to write a small C++ class derived from "vtkObject" that internally uses the C++ class library and translate the interface of the C++ class library to a simpler form that the VTK Wrapper generator can understand but before starting to write this class, I wanted to ask you some questions: 1. Is there a way of automatically wrapping C++ exceptions to the corresponding exception mechanisms of TCL / JAVA /Python etc. ? If there is no such thing (I guess there is nothing like that by now) what would be the best way to provide sophisticated error handling facilities to the script writers ? 2. Is there support for automatically wrapping "std::string" or "std::vector" arguments in C++ class-methods ? 3. Has someone ever used SWIG together with VTK and some scripting language (because it seams to support some of the features I am asking about) ? 4. Is it possible to pass out multiple strings to the scripting languages with just one call similar to the following C++ code: void passOutTwoStrings(std::string& string1, std::string& string2) { string1 = std::string( "one" ); string2 = std::string( "two" ); } 4. I was playing with the wrapper generator and it seamed that it considers the use of the C/C++ keyword "volatile" as a syntax error. Is there a reason for this behaviour ? I just used the keyword for a private attribute of a class. Thanks a lot for any help or suggestions in advance !!!

It's not clear how I'd define a loop that encloses a volume, though. Before receiving your response, I was experimenting with vtkImplicitDataSet, since that implements vtkImplicitFunction, which is what I need for my clipping. I thought, start with the vtkPolyData whose geometry I want to use to define my clipping function, pipe that into a vtkImplicitModeler, pipe that to a vtkImplicitDataSet...and pass that to the vtkClipPolyData's SetClipFunction method. This approach makes sense, and hooking up that pipeline does not result in any complaints from VTK. Unfortunately, the rendering doesn't show the clipping I want...so far. Do you think I'm at least on the right track?

If there is no reason why "volatile" should be rejected by the parser, it might be a good thing to have it accepted by the wrapper generator. Thanks again for your help !!!

I'd already tried "xhost +myhost" but as a last resort; I wouldn't have expected it to make any difference. My display is - bash-2.05a$ echo $DISPLAY myhost:11.0 *not* ":0.0". Perhaps the real question should be, why is vtk partially ignoring my $DISPLAY value? Ssh is listening on port 11 on myhost. It captures all of the X Client output, sending it back to my real host in its own encrypted tunnel. BTW, I tried this - export TCLLIBPATH=/contrib/vtk/VTK/Wrapping/Tcl vtk -display $DISPLAY \ /contrib/vtk/VTK/Examples/Modelling/Tcl/hello.tcl which gives me a grey-filled window labeled "vtk," no "Hello" graphic, no interaction, nada, and the only way I've found to get rid of it is to press Ctrl-C. If I leave off the -display - export TCLLIBPATH=/contrib/vtk/VTK/Wrapping/Tcl vtk /contrib/vtk/VTK/Examples/Modelling/Tcl/hello.tcl I get the "Hello" graphic, and I can interact with it, rotating, zooming, etc, just like I can with VTK 3.2.

(VTK is the most stable piece of the puzzle at this point!) The change to 10.2 introduced some changes to OpenGL and to fstream which are causing numerous tests to fail. That said, I recently committed some changes to VTK to deal with dynamic lib initialization which has fixed the build problems, and I tested this out by building from scratch on a virgin iMac over the weekend. There may be some problems if you have X11 installed on your machine. Currently you should be building with gcc3 only, as James just pointed out. I am also only working on Carbon builds at present, since all the tests use Tk windows and those are Carbon-based. I append a CMakeCache.txt file-stub that you can use. (put it in your build directory, name it CMakeCache.txt, run cmake again, then make) It assumes you have framework builds of Python and Tk/Tcl available in /Library/Frameworks. I am working on the vtkImageReader problem now. Once I have things building properly, I promise to update CMake to configure properly on OSX! --Apple-Mail-3--823110622 Content-Disposition: attachment; filename=NIGHTLYCMakeCache.txt Content-Transfer-Encoding: 7bit Content-Type: text/plain; x-unix-mode=0644; name="NIGHTLYCMakeCache.txt" //Build the local directory classes VTK_USE_LOCAL:BOOL=ON //Build VTK examples.

I'm new to VTK and after spending 1 month banging out a script to do a MRA MIP reconstruction from MRA images I can't seem to get it to look right. Plus, I have a few other questions and woul really appreciate help from anyone with a few moments to spare. My questions are as follows: 1. How do you figure out the proper opacity and color transfer settings? I've tried a few different things and it never looks quite right (I think this is at the heart of why it doesn't look like an MRA). 2. How can I display the axes on my image? With a simple example the add axis works, but not when I do a the full blown data set. 3. When I rotate the image it blurs. How can I control this? Also, the first time I rotate it rotates fine, but the second time (and every time after that) it's terribly slow, any explanation for this? 4. The MR scanner is going to give me coordinates and I want to be able to put a cursor at those coordinates and then move the cursor to different coordinates based on updated input from the scanner. I tried to draw a sphere inside my volume, but I can't see it (I know it's commented out in the code below, but I can't see it even when it's not commented out).

I was able to render your sample images okay but the slices don't seem to be a contiguous dataset (looks like maybe 3 sets back to back???)...maybe I just don't understand what the slices are. The easiest way to figure out the proper opacity and color functions is to load the slices up in VolView and use the interactive tools to sort it out (unfortunately this approach involves $$) You can download a trial version of VolView from Kitwares web site. Its really quite a nice tool to have on hand. The cheap way is trial and error. Examining the histogram can help with initial estimates however. You could always build your own interactive tools...I'm still looking for a tcl snippet to do this but no one's posted any yet ... hint hint (-; try this vtkPiecewiseFunction opacityTransferFunction opacityTransferFunction AddPoint 0 0.0 opacityTransferFunction AddPoint 75 0.5 opacityTransferFunction AddPoint 190 1.0 vtkColorTransferFunction colorTransferFunction colorTransferFunction AddRGBPoint 0 0 0 0 colorTransferFunction AddRGBPoint 75 0.8 0.8 0.8 colorTransferFunction AddRGBPoint 190 1 1 1 question 3....the blurring is a lower level of detail so the intereaction stays real time.

To realize this function, I think I should derive some vtk classes (e.g. vtkVolumeTextureMapper2D, etc.) and add GeForce3 functions (e.g. register combiners, etc.) into the derived classes. Does anyone have the experience to program combining VTK and GeForce3 graphics card to do volume rendering? Would anyone give me any ideas about combining VTK and GeForce card to do volume rendering? Thank you in advance.

I wondered about this approach, but I am worried about the cost of lots of pick calls .. and I expect lots will be needed to make sure no parts of the scene are missed and the rectangle is fully sampled. The scene may be very complex and it could be a major disaster of one of the elements (atoms) escapes the selection. It would seem to be a feature that would be best built into the vtk core somehow, but to be realistic I probably don't have the skills (or right now, the time) needed to do this. Maybe I could help at some time in the future with the support of someone who understands the current picking code. I understand from Will that there will be some vtk folks at SC 2002 so maybe we can talk it through then.

It will draw a multi-sided (min sides == 3) tube around lines composed of many points. First, define the points (vtkPoints) and lines (vtkCellArray), then call poly->SetPoints(points) and poly->SetLines(lines). You can then use poly as the input to a vtkTubeFilter. You will need to reapply the filter if you change the input points.

Now my problem is not data type. I imported short int data to vtkImageImport. Since I must do some operation on data, I have to import them from array to vtk pointer, instead of using vtk reader. Now it can be shown by vtkDataSetMapper. However, it can not be shown by vtkVolumeRayCastMapper. How can I solve this problem? By the way, the output of vtkImageImport is vtkImageData, not vtkStructuredPoints.

Oktober 2002 18:49 An: Chunyan Jiang Betreff: Re: [vtkusers] How to realize volume raycast? Hi Chunyan, The volume renderer will only deal with byte data. If you have anything else (eg floats) then you have to filter them first: vtkStructuredPoints* structPts = reader->GetOutput(); structPts->GetScalarRange(range); printf("Input field range: min = %.3f, max = %.3f\n",range[0],range[1]); // Convert to byte data because that's what the vol. renderer needs vtkImageShiftScale *imageShift = vtkImageShiftScale::New(); imageShift->SetShift(-range[0]); imageShift->SetScale(255.0/(range[1]-range[0])); imageShift->SetOutputScalarTypeToUnsignedChar(); imageShift->SetInput(structPts); and you'll be needing a imageShift->GetOutput() too. Hope this helps. Andrew. > Dear VTK users, > I import 3d image data to vtkImageImport. Now I want to realize volume > rendering.

I'm not sure -- thus far no one seems to have responded to this so I am guessing. Anyway a week or so back I mailed the list some code on how to get the VTK C++ object from Python into a C++ function. Surely something similar must be there for the Tcl and Java wrappers but I am not sure and have not looked. Under Python I think it should be fairly easy to use SWIG along with the VTK wrappers to do what you need to do. Again, I'm only talking about the Python side of things.

I havent done it but am fairly confident that it should be possible. Even if its not possible the way you want it there will be a way to pass strings from the scripted language to Python/Tcl/Java. I am not sure how you want to do the wrapping yet. If you want to write code by hand to wrap your classes pretty much anything should be possible.

Here's from the ssh man page, if it'll help understand the environment we have: Excerpt from "man ssh": If the user is using X11 (the DISPLAY environment variable is set), the connection to the X11 display is automati cally forwarded to the remote side in such a way that any X11 programs started from the shell (or command) will go through the encrypted channel, and the connection to the real X server will be made from the local machine. The user should not manually set DISPLAY. Forwarding of X11 connections can be configured on the command line or in configuration files. The DISPLAY value set by ssh2 will point to the server machine, but with a display number greater than zero.

Is the computer you are trying to display on called myhost? The DISPLAY variable needs to have the name of the computer you are trying to open the window on. In other words, if this is the same machine as you appear to have sent your mail message from, the DISPLAY variable should have "random:11.0" rather than "myhost:11.0". What I'm thinking here is if Xlib can't resolve the "myhost", it may be defaulting to using ":0.0" in place of the DISPLAY variable contents it can't resolve. John At 2:08 PM -0500 10/24/02, Tom G.

 Hi prabhu/Tim

Thanks for the response and it was very helpful. I have one more question to all the vtk users.

I am using stl reader and  vtkcelllocator to get a  line intersection point and its cellID. After this I tried to compute all the points that lie within radius of the intersection point.

To compute the points within radius I am using:

pointLocator->FindPointsWithinRadius(radius, ptline, res);

Question is: As I looked at the normal of all the points within radius I discovered that most of the points are from inside surface, where as my intersection point is at outside surface. How to compute all the points that lie only on the outer side of the surface?

The code I am using for this is :

vtkIdList *res = vtkIdList::New();

                        float radius = 2.0;

                       vtkPointLocator *pointLocator = vtkPointLocator::New();

                        pointLocator->SetDataSet(stlreader->GetOutput());

                        pointLocator->BuildLocator();

                        pointLocator->FindPointsWithinRadius(radius, ptline, res);

                        pointLocator->Update();

                        vtkIdType ptId;

                        float *pt;

                        int num_pts;

                        num_pts = res->GetNumberOfIds();

There used to be a problem like this with some of the older NVidia drivers, but that affected all renderwindows.

I'm new to OS X but I have plenty of experience with Solaris and Linux and I had assumed (incorrectly) that this would be a relatively straightforward task. I've been hacking at this for two days without much luck--I've checked the archives (I guess there was some pertinent info posted on the 24th--thank you), and I've employed the changes recommended but I'm still having trouble. Has anyone out there successfully pulled off a build with support for Java in Jaguar? When I run cmake I receive notification "failed to compile VTK extensions to CMake"--this is a little alarming but I'm not sure what to make of it. I do have Xfree86 installed as well--is this serving to jazz things up? I'm compiling with my latest modifications to the CMakeCache.txt file presently--I'll follow up with more specific information about the errors when it fails. Thanks in advance for any advice.

I'm having some problems with vtkTextureMapToPlane. I have to texturize a 3D model of an ancient theater, basicly planar (it's just the front of the theater, the "facade"). It is made of, let's say, a "big box", and some pillars laying a bit closer to the imaginary observer looking at its front side. Let's try to do some Ascii art (?)... viewing from the top: ________________________.... _____ __________ _____.... I__I I__I Got it (despite my english)? Hope so. Now, the problem is that I am using a perfectly planar texture map (representing a color map), as big as the facade, but I get some wrong color spots on the top of the pillars... I made some theories: 1) it's a bit like if the texture isn't mapped in a perfectly hortogonal way to the facade, but with a little angle... maybe? 2) the texture "fades" in the outer points.. the points far from the center are differently coloured 3) the 3D polydata come from a decimated STL model.. maybe the DecimatePro filter introduces some problem? (this is quite unlikely, but.. you never know :-) I cut&paste some code: tPuddinga = vtkTexture::New(); tPuddinga->SetInput(myMap->GetMap()); // myMap->GetMap() is a method returning a vtkImageData* tPuddinga->RepeatOff(); tmPuddinga = vtkTextureMapToPlane::New(); tmPuddinga->AutomaticPlaneGenerationOn(); tmPuddinga->SetOrigin (0, 0, 0); tmPuddinga->SetSRange(0, 1); tmPuddinga->SetTRange(0, 1); tmPuddinga->SetInput (riduttore->GetOutput()); // riduttore is the DecimatePro filter ...and so on, just trivial code. Anyone out there has got a clue? I thank you very much in advance.

You need to call vtkMapper::SetColorModeToMapScalars() to correct this. Also, set the correct scalar range of the LUT. You can do this directly, or you can call SetScalarRange on the vtkMapper.

I want the slices to fill in the whole render window. Therefore, I use: imgMapper->RenderToRectangleOn(); together with: imgActor->SetPosition(0.0,0.0); imgActor->SetPosition2(1.0,1.0); This works fine for my 256x256xK volumes but the slices of the 512x512xK volumes are cut off.

I'm not sure how this works under Windows though but I remember that someone tested it out and that it worked. 2. Put all the contents of Wrapping/Python inside this vtk_python dir. Also put the vtkPython*.dlls into this dir. 3. Copy vtk.pth to sys.prefix/lib/python-sys.version[:3]/site-packages. That is how the setup.py install command is supposed to work. I thought that the bdist_wininst should capture all that and work. Let me know if there are problems.

This should give you a successful build (tested on recent cvs ~2 weeks ago). It would also be nice to ask the person responsible for Java in "OS X" to include these hacks in the source tree.

Message-ID: Hello. Could use some tips. I have an MFC application with VTK embedded. I simply use vtk as a quick way to adjust camera position,etc. of a polygonal model(s). I would like to do additional rendering (raytracing/radiosity) in an opengl window. First I'd like to ask for pointers as to how to do this effectively. Second, I've already created an opengl window class - generic WIN32 implementation. The opengl window has its own event handler. My problems are as follows: (1) For now the opengl window simply renders a colored triangle (w/o raytracing,etc). When the window is created and the scene is rendered I seem to lose contact with the associated event handler. Specifically, in order for me to respond again to mouse events and the like I have to click outside the main application - either activate (bring to the foreground) another application or click on the taskbar slot [for lack of a better term] of the opengl window or main application window - then reactivate the opengl window. In other words, I have to deactivate (send to background) the main application or the opengl window, then reactivate (send to the foreground), in order for the opengl window to respond to messages. After this transition from foreground (after creation) to background to foreground, the messages seem like they are routed to the right handlers. NOTE: This problem occurs even when I create the opengl window in a simple AppWizard Generated SDI application. (see http://xtopia0.tripod.com/testcode/openglwintest.zip for the code ) (2) When I return to the main application I no longer can render anything using my VTK window. That window simply repaints - upon resize, move, etc - the scene prior to the spawning the opengl window. I can no longer use the vtkInteractor to change that scene (or perhaps I can use the interactor, but the rendering does not occur) or display other objects. I just get the scene prior to the creation and displaying of the opengl window. I suspect it may have to do with VTK's rendering context. Any suggestions on how to create/manage an separate opengl window in an MFC application using VTK would be greatly appreciated. And any help with (1) and (2) would likewise be appreciated. Thanks. ks From tdeschamps@lbl.gov Mon Oct 28 23:50:31 2002 From: tdeschamps@lbl.gov (Thomas Deschamps) Date: Mon, 28 Oct 2002 15:50:31 -0800 Subject: [vtkusers] Default parameters for rendering a surface obtained with vtkMarchingCube Message-ID: <3DBDCD47.2070502@lbl.gov> This is a multi-part message in MIME format. --------------060002040405040508070209 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Hi vtkUsers, I have problem, which is probably related to the way I set the display of a surface extracted by the Marching cube. I want to render a big cube of size 200x200x150 extracted with the marching cube algorithm (later I'll work on other shapes when this bug will be solved). The rendering gives me red faces for z-constant planes, and white faces for the 4 others. Do you know what is happening? The only modification done to the actor is to set is color to red. All other options are not set, therfore set by defaults. I do not know if I can include image in this email. I will try to do it, but if you know what's happening, or want the image, I can send it to you directly. Thank you for your help.

I want to render a big cube of size 200x200x150 extracted with the marching cube algorithm (later I'll work on other shapes when this bug will be solved). The rendering gives me red faces for z-constant planes, and white faces for the 4 others. Do you know what is happening? The only modification done to the actor is to set is color to red. All other options are not set, therfore set by defaults. I do not know if I can include image in this email. I will try to do it, but if you know what's happening, or want the image, I can send it to you directly. Thank you for your help.

I looked into the vtkProcessObject class and noticed the function SortInputsByLocality() (but could not find where and when it si called). (1) I am interested in knowing on what ocassions this function is called ? (2) Does this function help the vtkContourFilter work faster in some way by sorting the dataset in some way ? If anyone can please throw light on this, I will be really grateful. I have spent quiet some time looking at all the wrong places. Thank you in advance, regards, Joseph. __________________________________________________ Do you Yahoo!? Y!

I have one more question to all the vtk users. I am using stl reader and vtkcelllocator to get a line intersection point and its cellID. After this I tried to compute all the points that lie within radius of the intersection point. To compute the points within radius I am using: pointLocator->FindPointsWithinRadius(radius, ptline, res); Question is: As I looked at the normal of all the points within radius I discovered that most of the points are from inside surface, where as my intersection point is at outside surface. How to compute all the points that lie only on the outer side of the surface? The code I am using for this is : vtkIdList *res = vtkIdList::New(); float radius = 2.0; vtkPointLocator *pointLocator = vtkPointLocator::New (); pointLocator->SetDataSet(stlreader->GetOutput()); pointLocator->BuildLocator(); pointLocator->FindPointsWithinRadius(radius, ptline, res); pointLocator->Update(); vtkIdType ptId; float *pt; int num_pts; num_pts = res->GetNumberOfIds(); for (int i=0; i < num_pts; i++) { ptId = res->GetId(i); pt = poly->GetPoint(ptId); } Thanks in advance Siddu (Embedded image moved to file: pic06729.gif)Post your ad on Yahoo!

But MayaVi is able to visualize brain.vtk file and the interaction is normal.(i dont know how) the way i do is as follows: i create a assembly and add the actors(1000 actors one for each sphere)to it. I add the assemble to renderer. rendering is very slow in this case and interaction like zooming and panning are dead slow. Is this the correct way to create so many actors or is there any other way.

Also you could just render points rather than spheres. If you are using vtkGlyph3D with vtkSphereSource as input try reducing SetThetaResolution and SetPhiResolution. You can also use vtkMaskPoints to subsample the input data, on large data sets this can be a good way to still 'get the feel' of the data without displaying everything. hope this helps, Dave Pont From massimo.ivani@mlsw.com Tue Oct 29 10:59:14 2002 From: massimo.ivani@mlsw.com (Massimo Ivani) Date: Tue, 29 Oct 2002 11:59:14 +0100 Subject: [vtkusers] vtkRenderSource problems Message-ID: <004201c27f3a$3931c930$f254dfd9@compaq> This is a multi-part message in MIME format. ------=_NextPart_000_003F_01C27F42.9A24D770 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Hello, I used vtkRenderSource and vtkBMPwriter to create a bitmap from vtk = window.

Allows backface/frontface culling in wireframe and points representation. 2. Allows a backface property to be set in wireframe and points representation. 3. Speeds up wireframe rendering by 20% with BackfaceCullingOff and by 110% with BackfaceCullingOn (SB's bench-sphere.tcl on Dell Inspiron 3800- ATI Rage Mobility graphics card). Probably speeds up points rendering too (haven't tested it though). Other representation are unaffected- triangle strips are still the fastest primitive to render. 4. EdgeVisibilty could now be enabled when rendering surfaces in vtk (would take some more hacking). It seems EdgeVisibility is only used in the GeomView exporter. In a nutshell, the changes are that vtkOpenGLPolyDataMapper.cxx always draws triangles and vtkOpenGLProperty.cxx switches the representation using glPolygonMode( ) John Biddiscombe inquired about this back in Oct 1999... here's the thread: http://public.kitware.com/pipermail/vtkusers/1999-October/002446.html.

So the object can be rotated, zoomed and translated. Then I want to perform fly-in and fly-out the object, just like look through the 3d image in different directions. How can I realize it? Which class should I use? It seems that vtkImageReslice can not work with vtkVolumeRayCastMapper. At least I don't know how to handel them. Could any body give me some help? Thank you very much!

Message-ID: > How can I get the IDs of points connected to a single point (first-order neighbors) of polydata. Hi Mike, Just took a quick look at the documentation for vtkPolyData, I am using vtk 3.1 but probably the following is valid in later versions: Use BuildLinks to allow topological queries. Use GetPointCells with the target point to get all cells that point belongs to. For each cell use GetCellPoints to get the list of points used by the cell. For each point, (if it is not the target point) use IsEdge with the target point and the current candidate point, if true add this point to a list. That list should be the set of first-order neighbours. Something like that anyway... regards, Dave Pont From dean.inglis@on.aibn.com Tue Oct 29 20:45:31 2002 From: dean.inglis@on.aibn.com (Dean Inglis) Date: Tue, 29 Oct 2002 15:45:31 -0500 Subject: [vtkusers] CVS co of VTK - speed?

I'd suggest that you post small working examples in either C++ or a scripted language (prefferred) that require no data. Something like the example I posted. If speed is bothering you so much it just might be your hardware. If you have a lousy video card its likely you will not get any speed. On my el-cheapo TNT2 M64 the example I posted is slow (with 2000 spheres) but is definitely not "dead slow". Besides its perfectly useable when I switch to using vtkLODActors. However its easy to see that if I used a lousy card (or a very low end workstation) it would be dead slow. Rendering does require good graphics performance and thanks to the gaming industry decent cards today are fairly inexpensive. cheers, prabhu From Andrew.Porter@man.ac.uk Wed Oct 30 09:40:15 2002 From: Andrew.Porter@man.ac.uk (Andrew Porter) Date: Wed, 30 Oct 2002 09:40:15 +0000 (GMT) Subject: [vtkusers] setting break points in vtk source files in debugger In-Reply-To: <20021029194859.62500.qmail@web21503.mail.yahoo.com> Message-ID: <20021030093823.I4862-100000@nessie.mcc.ac.uk> > But when I try to do it, the debugger compalins that > there is no vtkConoturFilter.cxx source file. > You need to tell the debugger the location of any source files that aren't in the directory in which you are launching it. e.g. if you are using dbx then use the -I flag to specify the directory containing the relevant vtk cxx files.

I have no ideas how to solve these problems but you might want to
try another vtk-Qt-package, which is provided by Carsten Kuebler:

http://wwwipr.ira.uka.de/~kuebler/vtkqt/index.html

I'm using VTK4.0 and Qt2.3 under windows together with this
package and it works fine. It is very easy to handle and probably
the very latest package bringing VTK and Qt together.

I know there are reader classes in vtk for the vtk file format and I think there is one for ensight files as well. My question is what other formats have readers been written for? Has anyone written a reader for tecplot files or a general HDF5 reader? Anyone working on parallel IO for vtk? We deal with all sorts of users here with all sorts of data. Most of those we encounter are currently using Tecplot or IDL or AVS. They are interested in vtk and the biggest issue is data importing. That is why I ask about the other file format readers.

The image coordinate system is defined by the Origin and Spacing information that is attached to the image. When you use vtkImageChangeInformation to center the volume, you are modifying the 'Origin' of the image so that the origin of the coordinate system is at the center of the volume. If, after centering the volume, you apply a transformation via vtkImageReslice, just set the inverse of the ResliceTransform as the UserTransform of the Actors. - David -- David Gobbi, MSc dgobbi@imaging.robarts.ca Advanced Imaging Research Group Robarts Research Institute, University of Western Ontario On Wed, 30 Oct 2002, Steffen Oeltze wrote: > Dear VTK-users, > > I'm using the vtkImageReslice-class to apply rotation and reflection to a > volume.

And It not possible to use them in this kind package. That why I did some extensions to make it possible. And again, a lot of peoples trying to make possible use Qt for creating GUI for VTK programs. And there are a lot of solutions in this area. For example VTK have directory VTK/src/Examples/GUI with MFC examples for Windows and other. But there are no support for VTK-Qt developers for example. Ofcource you can do it yourself, but maybe It is time to stop it. Maybe It time for VTK officialy support Qt. We need It really, creating VTK-GUI application with best library for GUI's - Qt. -Denis Shamonin.

You should try vtkLODActor instead of vtkActor, and you can control the switch to lower LOD with vtkRenderWindowInteractor->SetDesiredUpdateRate( DisplayFramesPerSecond ); I see in your code that you use a value of 9 for SetThetaResolution SetPhiResolution. This is quite high if you have large numbers of points (81? triangles per sphere, * lots of points). Try lower values, OK you lose sphere quality but interaction is your problem. Spheres are useful glyphs (look the same from any angle) but they are costly in triangles. Try vtkCubeSource, I'll bet that cranks up the speed. But wait.... Interesting what a bit of reading can uncover, I just found a class I never knew existed: vtkLODProp3D, this looks as though you can set up mappers that have used spheres of differing resolution (for example), say 9, 6, 3; and have the renderer switch between them to try and get your desired update rate. You could also add a mapper directly from the point data to get points as a lowest level of detail. The earlier suggestion of using vtkMaskPoints, then to glyphs, could be used too... This sounds promising... I suppose the only danger is consuming all your memory with these multiple representations of the data, given it is 'large'.

This is also the reason some actors don't show up. If I don't call Render(), all the actors appear, and we get no X errors. Whether I call Render() or not, the visualization does not update itself. I have to interact with the mouse to get the updated scene drawn. 3) There seem to be interesting things going on with the default camera. ResetCamera() consistently causes a BadAccess error, and Dolly() causes the "unexpected async reply". If I don't mess with the camera or call Render, we get absolutely no X errors.

Maclean for fixing various bits and pieces. I've tested it fairly thouroughly against a range of polydata datasets and put some checks in to prevent floating point errors when degenerate data and/or other dubious polygons are supplied - but there are almost certainly going to be a few possible cases which cause trouble.

I really havent had too many other problems with gcc 2.96, but until i tried 3.0.4 i thought it might have been a 2.96 problem. I will give 3.1 or 3.2 a go soon, and i will then hope that i have seen my last internal compiler error... generally when i get such internal compiler errors, it seems by that time my whole computer is bollocksed up... if i try to continue the VTK make it will fail again with the same internal compiler error at the exact same point. But if i then do a re-boot, and re-start the make it will continue happily for some time until the next internal compiler error. I usually get 2 or 3 internal compiler errors before the VTK make is complete. This problem happens with VTK 4.0, and VTK CVS, and it has also made compiling the Glasgow Haskell Compiler a horror. I have been assuming its possibly a hardware problem, like a few unreliable memory bytes which dont really cause too many problems unless i give my box a good workout by compiling something rather large like VTK or GHC -- but... does anyone else out there get any of these rotten internal compiler errors? im really really sick of them... compiling VTK is not a quick and simple process even if things go smoothly, but when you start it compiling and then go to bed expecting to wake up to a brave new world of improved VTK ... and then in the morning you find the compilation died after an hour and there are several hours of compilation left to go after a reboot it makes you want to pull your hair out. argh !

Most C++ examples in the Vtk source tree will probably call XOpenDisplay() in vtkXOpenGLRenderWindow as their first X call, but granted; non of these are multi-threaded and so they will not suffer from this problem. Anyway; now that I've given it a little more thought - vtkXOpenGLRenderWindow is, indeed, probably not the right place. > Another solution is to make the call from your own program, Agreed; we should add a note about this in the FAQ. But I think there is a little bit more we could do; I noticed that some of the Vtk interfaces to X windows GUI toolkits (i.e. Qt, Fltk, etc) use a multithreaded approach to split Vtk's and the toolkit's event handling loop - these interfaces should call XInitThreads at initialization. > or better-yet to make sure that you only modify the render > window from a single thread. You mean; make sure that you only access *the X server* from one thread. The renderer is not the real issue. However, there are advantages to multithreading an application *and* have the different threads access the same server.

The renderer is not the issue, but the render window is (specifically vtkXOpenGLRenderWindow, vtkXOpenGLTextMapper). These classes make glx calls, and are pretty much the only entrance points into X from VTK. My suggestion to make sure that methods like Render() (or any other method resulting in a glx call) be called from a single thread is one solution, although admittedly broad-brushed. This solution works well for Java (disturbingly multithreaded), where XInitThreads cannot be called before the jvm initializes X. As stated above, the gui-toolkits are the place to take care of X thread safety. I don't have alot of faith in XInitThreads (seems like a black box, not a robust solution), but I know that mutual exclusion locking works fine. -Jeff > >-- Rob > > > From jss@au.mensa.org Thu Oct 31 13:16:36 2002 From: jss@au.mensa.org (John) Date: Thu, 31 Oct 2002 23:46:36 +1030 Subject: [vtkusers] Compiling error under Redhat 6.2 (actually mandrake 8.2) In-Reply-To: <15809.1501.582799.844785@monster.linux.in> References: <3DBD8133.44D9E0C6@earthlink.net> <20021031061035.7E92A1AA40@public.kitware.com> <15809.1501.582799.844785@monster.linux.in> Message-ID: <20021031131521.83B651AA40@public.kitware.com> thanks Prabhu, i ran one pass of the standard memtest86 tests and my computer passed, which surprised me. I will set it to run the extended tests overnight, and see if they can detect anything. The cpu fan is definitely running... i was worried about my cpu fan about a month ago, as I am a smoker, and the tar/fluff build-up in my computer fans is absolutely disgusting. So i popped the fan assembly off my P3 and gave it a good clean a short while ago, and the fan was working perfectly afterwards. I was getting the internal compiler errors before and after the clean tho :( Also it is the end of winter here in Australia, so im pretty sure the problems i have been having in the past, ie in winter, were not due to overheating. I still think it is probably a memory problem, especially if you havent heard of this sort of thing being compiler or OS-related... And after all, the memtest86 took less than an hour to run one pass of its standard tests, and i tend to get the internal compiler errors after an hour or more of compilation.... So it seems to me that maybe the VTK compilation is using a section of memory which is a little tiny bit unreliable, and using it heavily, until it has failed enough to confuse the compiler. Whereas the memtest86 is wasting time testing my entire memory range, and not testing any particular section very heavily. If this internal compiler error is not a common problem, then I am satisfied that it must be an intermittent hardware error with my computer, and i wont worry about it too much, as i should be upgrading my motherboard and RAM soon. i will let you know if a more thorough memory test detects any problems tho. And I will mention one more small but weird problem Ive noticed in my next email... thanks again, John On Thursday 31 October 2002 08:58 pm, you wrote: > >>>>> "J" == jss writes: > > J> Hi, i also get these filthy internal compiler errors all the > J> time, its horrific. > > I'm almost certain it is a hardware problem.

Hello vtkusers,

I am new to vtk and got the following problem:
I am using vtkVectorText in a vtkFollower actor and want to pick it with a vtkPropPicker.
After starting the program the picker works fine until I rotate the scene to a new
camera position. Then the picker cannot find the actor again.
It seems that the follower actor isn't really where it is rendered.
Is there a need of refreshing the matrix of the follower?

Thanks!

Generally this error occurs when you are zoomed out too far from a volume. The VolumePro 1000 has a limitation on how far apart (in voxels) two neighboring rays can be - if you descrease your window size and/or zoom out farther from the volume you will exceed this limit which will cause the error message.

From vtkRenderer you can get an instance of vtkCamera from the GetActiveCamera call. You should be able to query the vtkCamera for all the information you would need. Kevin.

Now, when I put the camera on the back of the scene (lets say Azimuth = 180), and I have two actors aligned, it picks the one that is on the BACK instead of the one on the FRONT! Any idea?

Use vtkCGMWriter to write a scene to file. This class is included in vtk4.n but it is not built... so you have to add it yourself to the cmake files and re-compile. Under windows and the borland compiler there were a couple of small bugs. Email me if they cause you any problems. 2. Download and install the universal postscript printer driver from adobe. 3. Insert the CGM file into a Word document. Make sure Word has the CGM graphics importer installed 4. Print the Word page to a PS file using the PS printer driver. 5.

Maybe the problem was there. I don't know the following may help or not, but in an old code I had the filename also as the last argument of gl2psBeginPage{...char *filename; File *fp = fopen(filename,"w");...;gl2psBeginPage(...,filename);...}. I can't remember why I did that.

I'm not the expert on this since David Gobbi wrote the implementation but here is my explanation of how things work. I'll let David correct me if I'm wrong. The VTK-Python wrappers are a thin layer around the VTK library. As you must be aware, VTK has its own reference counting mechanism. When a VTK object is used by another the object increases the reference count of the object it uses. When it no longer needs the object the objects refcount is decremented and when it drops to zero the object is destroyed. Its the same as in Python. So here is an example demonstrating how it all works: >>> import sys >>> import vtk >>> cs = vtk.vtkConeSource() >>> out = cs.GetOutput() >>> print sys.getrefcount (out) 2 >>> print out.GetReferenceCount () 3 >>> m = vtk.vtkPolyDataMapper() >>> m.SetInput(out) >>> print out.GetReferenceCount() 4 >>> print sys.getrefcount (out) 2 >>> o = out >>> sys.getrefcount (out) 3 >>> print out.GetReferenceCount () 4 # Now how are objects deleted? >>> print cs.GetReferenceCount() 3 >>> print sys.getrefcount(cs) 2 # Now turn on debug to see if the object is indeed deleted. >>> cs.DebugOn() >>> del cs Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 230 vtkConeSource (0x819e468): UnRegistered by NULL, ReferenceCount = 2 Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 230 vtkConeSource (0x819e468): UnRegistered by NULL, ReferenceCount = 1 >>> # this object is not deleted because out still holds a reference # internally. >>> del out # still nothing happens because GetOutput() is still held by the # mapper. >>> del m Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 225 vtkConeSource (0x819d1d0): UnRegistered by vtkPolyData (0x8136640), ReferenceCount = 0 Debug: In /skratch/prabhu/vtk/cvs/VTK/Common/vtkObject.cxx, line 126 vtkObject (0x819d1d0): Destructing!

How about the following: Take the case where I want to replace a section of the visualisation pipline. Source->Filter1->Filter2->Mapper If I disconnect the pair of filters (for example) by resetting the inputs and outputs of the mapper and source respectively, to replace them with some other filters, how do I destroy the redundant Filter1 and Filter2? According to my understanding, using del Filter1 del Filter2 will simply remove the label for each filter (hence decreasing their ref-counts by one). However Since the filters are still connected to each other, they still have references >=1 so are not destroyed. Thus I must break the connection between the filters before they are destroyed. How do I do this? Can I set their inputs to NULL?

Now I'm using the AddObserver() function to execute a vtkCommand that updates the input position but then the process never exits the command to continue the pipeline.

Message-ID: <001701c26a2c$31a81700$b92d8280@atp.tuwien.ac.at> Dear vtk-users! For my "CAD-like" application I need serveral (4) views (front, top, left, perspective) of the same set of actors. I am new to VTK, so I first modified the "...GUI\Win32\SampleMFC" and added a CSplitterWnd to the childframe. The behavior of this was little strange: in some panes (of the splitterwnd) the actors were not rendered. I read the mailinglist and noticed that each renderwindow needs his own actors and mappers. So I rewrote the mfcsample and added an actor and a mapper to each view sharing the same "vtkPolyData" as input. Now erverything works fine until I maximize the CChildFrame: If I use the Inteactor of the bottom-left pane, the renderd scene is displayed in the top-right pane. (ImmediateModeRenderingOn() had no effect on this) (I am using vtk 4.0 and WIN98) Can anybody tell me what is going wrong, or is there an example of how to use splitterwindows or multiple views with VTK?

I tried to compile the nightly release from today using cygwin and gcc-2.95-3, but during the linking stage of the libvtkRendering library I always have the problem that the references to all the open gl functions are undefined : (last line of error messages for static libraries): ... /cygdrive/g/Tools/VTK/bin/libvtkRendering.a(vtkWin32OpenGLTextMapper.o)( 3b45):vtkWin32OpenGLTextMapper.cxx: undefined reference to `glPopMatrix' collect2: ld returned 1 exit status make[3]: *** [/cygdrive/g/Tools/VTK/bin/vtk] Error 1 make[2]: *** [default_target] Error 2 make[1]: *** [default_target_Wrapping_Tcl] Error 2 make: *** [default_target] Error 2 A similar problem also occurs if I try compile shared libraries, only then the linker already complains when it tries to build the library libvtkRendering.dll (also with undefined references to open gl calls). I have the cygwin open gl files installed (/usr/lib/include/GL/gl.h , /usr/lib/w32api/opengl32.a) and the opengl32.dll from windows is in the cygwin path. Does anybody have any hints how I can get this to work? Are there any special flags for cygwin/opengl that I need to set in the CMake config files?

It seems that the vtkVolume class provides the functionality I need in a prop/actor. However, vtkVolume is constrained to using a vtkVolumeMapper, which is constrained to using a vtkImageData as its input. This is a problem because I want to build a volume rendering mapper that accepts a vtkUnstructuredGrid as its input. Is there a way to use the vtkVolume class with mappers that do not render vtkImageData, or is there a trivial change that could be made that would allow it to? Adding a vtkAbstractVolumeMapper between vtkAbstractMapper3D and vtkVolumeMapper might do the trick. Or is it really necessary to write a separate prop class for volume rendering each of the vtkImageData, vtkRectilinearGrid, vtkStructuredGrid, and vtkUnstructuredGrid data object types? -Ken **** Kenneth Moreland *** Sandia National Laboratories *********** *** *** *** email: kmorel@sandia.gov ** *** ** phone: (505) 844-8919 *** fax: (505) 844-9297 -------------- next part -------------- A non-text attachment was scrubbed...

If not, vtkFlRenderWindowInteractor has been tested to work with fltk1.1.0rc3, so it should work with 1.1. AFAICS, FLTK 2.0 has not been released yet.

Under JDK 1.4.0 the vtkPanel (version 4.0) won't work because it is in an un-named package. I'm not sure if this is the case in JDK 1.3.1. The problem is fixed in the nightly source release; try building that.

I am working on Windows 2000 with the VTKNightly dated 10/02/2002. - At launch of the script wxVTKRenderWindow.py, a window appears, but nothing is displayed inside. Things become correct when I resize the window. (This was also reported by Chandra Shekhar, see http://public.kitware.com/pipermail/vtkusers/2002-October/013700.html) I could fix this problem, by changing the line 164 by : try: size = parent.GetSize() except: size = wxDefaultSize The try/except is used to protect the call to parent. - When the script wxVTKRenderWindow.py is launched and when killing the window (by clicking on the window close button, the one with a cross at the upper right), I get the following error message in the Python console : runtime error R6025 - Pure virtual function call This odd/bad behavior desapears when I add the line : widget.GetRenderWindow().RemoveRenderer(ren) at the end of test script, just after the line containing the "MainLoop" function. But I think that the problem is in the class wxVTKRenderWindow : Renderers might be refered to after they have allready been deleted/gced. To address this problem one could handle the proper deconnection of the RenderWindow from it's renderer[s] by adding a destructor to the wxVTKRenderWindow class. The following does the job for me: def __del__(self): renderers = self._RenderWindow.GetRenderers() numRenderers = renderers.GetNumberOfItems() self._CurrentRenderer = None renderers.InitTraversal() for i in range(0,numRenderers): self.GetRenderWindow().RemoveRenderer(renderers.GetNextItem()) Thanks for considering those problems.

Is there a reason for this? Is it "political", or technical? From my investigations, based on the platform we're using (Mac OS X, using PowerPlant) it should be relatively trivial.

Many of the examples dont build a GUI and simply illustrate the power of VTK alone. Some of them do build GUI's.

I am revising an application from using VTK 3.1 to 4.0 and I ran into an inconsistency in the result returned by vtkCamera::GetOrientationWXYZ. This is illustrated by the following C++ sample code: #include "vtkCamera.h" void main() { vtkCamera *cam = vtkCamera::New(); cam->SetPosition(40.5388, -58.1675, 36.4357); cam->SetFocalPoint(12.5875, 11.3799, 10.3485); cam->SetViewUp(-0.221512, 0.263181, 0.938972); cam->ComputeViewPlaneNormal(); // Needed for VTK 3.1 cam->OrthogonalizeViewUp(); float *wxyz = cam->GetOrientationWXYZ(); cout << wxyz[0] << " " << wxyz[1] << " " << wxyz[2] << " " << wxyz[3]; } When run using VTK 4.0 (nightly release, Oct 1, 2002), I get 284.514 0.937559 0.129517 0.322812 When run using VTK 3.1, I get 75.4863 0.937559 0.129517 0.322812 The first number (angle) differ in the two results. I think the number returned by VTK 4.0 is incorrect for the following reason. The method vtkCamera::GetOrientationXYZ() is used only in 2 classes, one of which is vtkVRMLExporter. In VTK3.1, vtkVRMLExporter generates a correct vrml file. In VTK4.0, vtkVRMLExporter does not generat a correct vrml file (the viewpoint is oriented in the wrong direction). Tracking the computation through the source code of VTK 3.1 versus 4.0, the main difference occurs in the row-column indexing of the matrix in the class vtkTransform. In particular, the method vtkTransform::GetOrientationWXYZ() is void vtkTransform::GetOrientationWXYZ(double wxyz[4]) { int i; this->Update(); // convenient access to matrix double (*matrix)[4] = this->Matrix->Element; double ortho[3][3]; for (i = 0; i < 3; i++) { ortho[0][i] = matrix[0][i]; ortho[1][i] = matrix[1][i]; ortho[2][i] = matrix[2][i]; } //...etc where ortho is subsequently used to compute w,x,y,z. If I transpose the ortho matrix, that is, change the above loop to for (i = 0; i < 3; i++) { ortho[i][0] = matrix[0][i]; ortho[i][1] = matrix[1][i]; ortho[i][2] = matrix[2][i]; } and rebuild VTK 4.0, then the above sample program gives the same result as that of VTK3.1. Also, the vrml file exported by vtkVRMLExporter is correct (viewpoint looks at the correct direction). The above suggests that either (1) the elements in the matrix of vtkTransform are stored in reversed row-column order, or (2) the row-column index is reversed somewhere during the computation of wxyz. Hope the above makes sense.

I am revising an application from using VTK 3.1 to 4.0 and I ran into an inconsistency in the result returned by vtkCamera::GetOrientationWXYZ. This is illustrated by the following C++ sample code: #include "vtkCamera.h" void main() { vtkCamera *cam = vtkCamera::New(); cam->SetPosition(40.5388, -58.1675, 36.4357); cam->SetFocalPoint(12.5875, 11.3799, 10.3485); cam->SetViewUp(-0.221512, 0.263181, 0.938972); cam->ComputeViewPlaneNormal(); // Needed for VTK 3.1 cam->OrthogonalizeViewUp(); float *wxyz = cam->GetOrientationWXYZ(); cout << wxyz[0] << " " << wxyz[1] << " " << wxyz[2] << " " << wxyz[3]; } When run using VTK 4.0 (nightly release, Oct 1, 2002), I get 284.514 0.937559 0.129517 0.322812 When run using VTK 3.1, I get 75.4863 0.937559 0.129517 0.322812 The first number (angle) differ in the two results. I think the number returned by VTK 4.0 is incorrect for the following reason. The method vtkCamera::GetOrientationXYZ() is used only in 2 classes, one of which is vtkVRMLExporter. In VTK3.1, vtkVRMLExporter generates a correct vrml file. In VTK4.0, vtkVRMLExporter does not generat a correct vrml file (the viewpoint is oriented in the wrong direction). Tracking the computation through the source code of VTK 3.1 versus 4.0, the main difference occurs in the row-column indexing of the matrix in the class vtkTransform. In particular, the method vtkTransform::GetOrientationWXYZ() is void vtkTransform::GetOrientationWXYZ(double wxyz[4]) { int i; this->Update(); // convenient access to matrix double (*matrix)[4] = this->Matrix->Element; double ortho[3][3]; for (i = 0; i < 3; i++) { ortho[0][i] = matrix[0][i]; ortho[1][i] = matrix[1][i]; ortho[2][i] = matrix[2][i]; } //...etc where ortho is subsequently used to compute w,x,y,z. If I transpose the ortho matrix, that is, change the above loop to for (i = 0; i < 3; i++) { ortho[i][0] = matrix[0][i]; ortho[i][1] = matrix[1][i]; ortho[i][2] = matrix[2][i]; } and rebuild VTK 4.0, then the above sample program gives the same result as that of VTK3.1. Also, the vrml file exported by vtkVRMLExporter is correct (viewpoint looks at the correct direction). The above suggests that either (1) the elements in the matrix of vtkTransform are stored in reversed row-column order, or (2) the row-column index is reversed somewhere during the computation of wxyz. Hope the above makes sense.

Message-ID: <28C3497E-D79F-11D6-8580-000393686412@chalkie.org.uk> Dear all, I'm trying to volume render a set of 20 z slices in tiff format in a tk window using a python script modified from one found at atamai.org (tkvolumelod.py) My data seems not to be read properly. The tiff files are from a confocal microscope, and are a series of z slices through a living cell. Data is from PC, but I am doing this on linux, so I have to SetDataByteOrderToLittleEndian() right (see script below)? The data should look like a hollow half sphere, but appears as arrays of little rectangles, no matter how I adjust the opacity and colour transfer functions in the script. My python script is below (modified from atamai.org so it reads tiff files as a dataset) I am using vtkTIFFReader, and believe I am specifying the fileseries as a 102x119x20 data set with 1x1x3 spacing. my command is like python volrendscript.py fileprefix my tiff files are named for instance fileprefix01.tif fileprefix02.tif etc . to fileprefix20.tif In gimp if I look at one of the tiff images in the middle of the stack and do a histogram I can see that there a re pixels of all values from 0 to 255. It seems like data is loaded and something is displayed (no segmentation faults, or other errors at the command prompt, and I can rotate it around and zoom just fine), but it looks nothing like the images the rendered dataset is made from. The bottom of the stack seems to be displayed with high values (in my case green) and the higher slices are orange then red at the top. Seems like the problem might lie here? Hope someone can spot my problem...I'm stumped!

See the examples at http://public.kitware.com/VTK/doc/release/4.0/html/c2_vtk_e_2.html#c2_vtk_e_vtkTextMapper annotatePick.tcl does what you want, except it does so when the user presses 'p' instead of mouse-clicking.

IIRC __del__ is actually called only after the window is killed and any "bad behaviour" can occur when the window is alive. Ok, there is the case that the window is dead and the actors are still alive. But are we guaranteed that __del__ will be called as soon as the window is destroyed? The order of destruction of the objects also matters here. I dont remember clearly but is there a way to always call a function *before* a widget (I mean any widget) is destroyed and not at object destruction? If the renderers maybe removed in that function. However, its been a while since I used wxPython so I cant remember the exact thing to do. Could any experienced wxPythoners comment on this? cheers, prabhu From fusion at thuule.pair.com Fri Oct 4 16:32:37 2002 From: fusion at thuule.pair.com (Alan McIntyre) Date: Mon May 24 19:15:50 2004 Subject: [vtkusers] vtkInteractorStyle References: <3D9DC5EB.30507@student.uni-magdeburg.de> Message-ID: <3D9DFAE5.7090707@thuule.pair.com> Steffen, The "void(*f)(void *)" parameter is a pointer to a C function that looks like this: void func(void *); How much that helps you out I don't know.

I think the '&' in the second example isn't necessary in the eyes of some (most?) compilers, but having it there doesn't do any harm as far as I know. The second example is the one you want in your particular case. As for passing a C++ class method in as the parameter to SetLeftButtonPressMethodArgDelete, I'm not exactly sure about the 'proper' way to do that, since it appears to be expecting a plain C function. What kind of compiler error are you getting? I don't have the VTK source on my machine here at home right now, so I'm kind of in the dark as to the usage/behavior of SetLeftButtonPressMethodArgDelete, but I'm wondering if the reason the it expects a pointer to a function with a void* parameter is so that class methods can be given to it. If I recall correctly, isn't the pointer to the object pushed onto the stack (kind of like an invisible first parameter) when calling class methods? If that's the case, perhaps the get_mousePos(void*) method in Steffen's example could be passed if it was declared like this: void get_MousePos(); Somebody please let me know if I'm totally clueless here; I don't want to give Steffen any bad info.

Dharmendra, Take a look at the vtkLODActor class: http://public.kitware.com/VTK/doc/nightly/html/classvtkLODActor.html It allows different levels of detail for interactive updates versus static display. The lower the level of detail, the faster the rendering.

It looks like you have built both Python and VTK with the static Tcl/Tk libraries. Maybe you should recompile both Python and VTK to use the shared versions of Tcl/Tk. For VTK make sure CMake is using the shared version. TCL_LIBRARY:FILEPATH=/usr/lib/libtcl8.3.so TK_LIBRARY:FILEPATH=/usr/lib/libtk8.3.so Or whatever appropriate version is on your system. BTW, do the VTK Tcl/Tk examples work ok?

In one configuration a VTK window is used to draw 2D text. When the text is displayed, it is drawn as expected at the lower left corner of the screen. I have tried various methods to set the origin to the top left for user convinience. The only method I can find that works is SetPosition. To make this effective I need to get the height of the text then use the window height to calculate the offset. GetHeight returns 0.0 so that doesn't work. The rest of the text in embedded in the code below. text_ = vtkActor2D::New(); vtk_renderer_->AddActor( text_ ); text_mapper_ = vtkTextMapper::New(); text_->SetMapper(text_mapper_); vtk_renderer_->AddActor(text_); vtk_renderer_->SetBackground(0.0,0.0,0.0); text_mapper_->SetFontSize(12); text_mapper_->BoldOn(); If I use any of the next four lines the text does not show up at all text_mapper_->SetVerticalJustificationToTop(); text_mapper_->SetVerticalJustification(VTK_TEXT_TOP); text_mapper_->SetJustification(VTK_TEXT_CENTERED); text_mapper_->SetJustificationToCentered (); } text_mapper_->SetInput(str_ptr); the line belows always returns 0.0 float height = text_mapper_->GetHeight(this); The line below works but is not flexible enough to handle different string lengths text_->SetPosition(10.0, 80.0); There is another GetHeight that from the description might work but it requires the address of a vtkViewport. How do I get one of these?? Is there a more flexible way to get the text origin to be the top keft corner of the window?? Did I use the set justification methods incorrectly?

Message-ID: <5.1.0.14.0.20021007130824.00ab8100@mail.viz-solutions.com> I just tracked down what looks like an odd bug, and I was wondering if anyone out there had any insight. I'm using a vtkPolyDataReader object to field incoming polydata definitions through a socket. I do this by reading the polydata from the socket into a string, then using the input string in the vtkDataReader. Everything generally worked fine, except in some cases the pipeline would not update when new data came down the socket. Eventually I tracked the problem down to vtkDataReader::SetInputString which, before assigning the string, does a string compare between the old and new string. When the new and old datasets were very similar (usually identical geometry, slightly changed scalar values) the strncmp would return a match. The string length was correct, and once the string compare was removed, everything worked fine. I'm working on a Windows 2000 machine with VC++ 6.0. I'm about to try the same thing on IRIX and Linux to see what happens, but I was wondering: 1. Has anyone seen this kind of behavior before? 2. Should the string compare really be there at all, given that these strings could be very long? Regards, Kevin.

I'm not sure what you are seeing is a bug per-se - does your Irix/Linux build do the same thing? I agree that the string compare could be expensive, but the dataset update could be even more so. I have been told that the data readers/writers are going to change in the near future to xml anyway, but it would be good to know if this is just a windows problem. I have been using the socketcommunicator for quite some time and it doesn't exhibit these symptoms.

I think its entirely possible that the vtk socket code does demonstrate the same symptoms. As I said, for some reason, it only happens when the incoming polydata only changes slightly from the version currently in the reader. It would be difficult to extract the code that I'm seeing this on, but perhaps I'll try to make a small sample that exhibits the same symptoms. As far as the cost of the string compare, it seems to me that by uploading the responsibility of that check to the caller of the reader, you give the programmer the option to either spend the time checking, or not. In my case, I'm performing that check already before sending the data down the socket, so its purely wasted time for me. Its a small point, but perhaps even a "no check" option would be a good addition to the reader. Thanks for the feedback Jeff.

Message-ID: Nothing to do with the possible bug, just something <=2c worth, To speed up the case where two very long strings are different can you first compare string lengths? Ie if the lengths are different the strings are different, which should save some time in that case. Where the lengths match then the full compare is needed. Another trick, which is no use as a general approach, but can be used in specific applications: If long strings typically carry a prefix which changes slowly, and a suffix which changes more rapidly, it can be much more efficient to do your own compare (when the lengths are equal) by comparing chars starting from the end and advancing towards the front of the string. regards Dave Pont |--------+---------------------------------> | | Kevin Wright | | | | | | Sent by: | | | vtkusers-admin@public.k| | | itware.com | | | | | | | | | 08/10/2002 10:32 | | | | |--------+---------------------------------> >------------------------------------------------------------------------------------------------------------| | | | To: vtkusers@public.kitware.com | | cc: | | Subject: Re: [vtkusers] string compare bug? | >------------------------------------------------------------------------------------------------------------| At 05:13 PM 10/7/2002 -0400, you wrote: >>>Are you using vtkSocketController/vtkSocketCommunicator?

I think its entirely possible that the vtk socket code does demonstrate the same symptoms. As I said, for some reason, it only happens when the incoming polydata only changes slightly from the version currently in the reader. It would be difficult to extract the code that I'm seeing this on, but perhaps I'll try to make a small sample that exhibits the same symptoms. As far as the cost of the string compare, it seems to me that by uploading the responsibility of that check to the caller of the reader, you give the programmer the option to either spend the time checking, or not. In my case, I'm performing that check already before sending the data down the socket, so its purely wasted time for me. Its a small point, but perhaps even a "no check" option would be a good addition to the reader. Thanks for the feedback Jeff.

Butler) Date: Mon May 24 19:15:52 2004 Subject: [vtkusers] Picking Glyphs? Message-ID: Does anyone have example code of picking glyphs? I want to be able to get the point the glyph was constructed from as a result of a pick operation. I gather from the web page on Glyph3D that the "GeneratePointIds" option is desireable. A fragment of the Tcl code I have is: vtkUnstructuredGridReader ugr ugr SetFileName ptdata.vtk vtkConeSource cone vtkGlyph3D glyph glyph SetInput [ugr GetOutput] glyph SetSource [cone GetOutput] glyph GeneratePointIdsOn vtkPolyDataMapper glyphmapper vtkActor glyphActor proc endPick {args} { # What code here? } vtkCellPicker picker picker SetEndPickMethod endPick Two things are wrong here: 1) The bounding box is drawn around the whole collection of points, whereas I want to box just the glyph selected. 2) I can't seem to find a way to identify the original point from the glyph through any accessor methods. Can anyone tell me how to access the original point from within the endPick routine? The cell reported by the picker is one for the polygon of the cone. It seems to have only coincidental relationship to the original point. Can anyone tell me how to change the behavior of picking away from drawing the bounding box? If anybody cares, I've attached the point data file Lee A.

I meaned is it from DICOM, *.BMP or *.Tiff...........image format. I tried different software like ACD See, ezDICOM, Photoshop, Image, AutoCAD, PhotoEdit......but failed. It can only be opened by Vtk program. which commercial Software could open it except VTK ? By the way,I also got a stack of brain slice files from Mimic software package. I did not know which image format about it. And how can I open the slice except Mimic & Magic software provided by Materialize Co. Because I think when we study it. We must know the property of the slices. Not only the 64X64X93 16 bits Color but also where it comes from. Is it the raw data or pre-processed? Could it be opened by another common Software? I just want to know these. Because I am a newer in VTK, did any expert share some idea about the Image process & 3D Reconstruction about the stack of Slices. I am interested in Rapid Prototyping Technique such as SLS & 3D Printing Using in Medical Area. I used VTK in Model Reconstruction field. We can make the friend if Anyone is interested in.

If the renderers maybe removed in that function. The runtime error R6025 is a specific Windows error. But it seems that on Linux, we sometimes obtain a core dump. Unfortunately, I can't certify the behaviour of events between the closing and the destruction in memory of the window. But the problem that we have appears after the window's destruction. I have discovered Python recently, and I don't know all mechanisms under this langage. But this destructor realize a clean destruction of the wxVTKRenderWindow instance. So, I think this destructor isn't bad, moreover it solves runtime error problems on windows and core dump problems on linux. But if these errors persist, I'm ready to search a best solution (when I'll know all specifications of garbage collector :) ).

Pardon me for lack of order in this file. I did this as test long time ago and I just attach it here to convey the idea.. First of all it is written for non MFC win32 application. In the WinMain there is a call to set up vtk (method : myVTKApp) Here I use directly vtk window. If you don't want this use SetParentId on the renderwindow and pass the window handle. Inside the myVTKApp there is a call to set the winproc (GetWindowLong). (I used two winprocs (1,2) to understand the behaviour , but you need only one winproc). Your mouse, key event arrives at the winproc and it could be either WM_CHAR or any other. So there you have the event and now you can do what you want with it. If you just want to pass it to vtk use vtkHandleMessage2 to pass it to vtk. With this you know exactly what interactions are happening and it is completely in your control.

If I had to guess, I would say that its a visual C++ bug, I just meant that the vtksocket code may exhibit the same problem when using vc++. I'm actually using the 4.0 release, the strncmp is on line 200 of that version. I just checked the nightlies, and it is on line 178 of that file. There are multiple versions of SetInputString, all of which end up calling the version with the string compare in it.

Here is some python pseudo code: fa = vtkFloatArray() pnts = vtkPoints() # create your points. for i in range(pnts.GetNumberOfPoints()): pnt = pnts.GetPoint(0) scalar = function(pnt) # your function fa.InsertNextValue(scalar) Now you can use the vtkFloatArray to do what you want.

Suppose your vectors are in a dataset call ds. 1. Create a vtkFloatArray (one component) consisting of vector norm (scalar value) at each point. Suppose this array is called "norms". 2. Put this array into the data set as scalars. In C++, this would be ds->GetPointData()->SetScalars(norms); 3. Use vtkThresholdPoints to extract only those points having scalar value (vector norm) between the two desired values. Hope this helps.

The compilation generates warnings of the following type: "/VTK/Common/vtkDataArray.cxx", Line 655: Warning (Anachronism): "static" is not allowed and is being ignored. This warning message is a result of running the following compilation command: CC -I/VTK/Common -I/VTK/vtkRendering etc etc -c VTK/Common/vtkDataArray.cxx -o vtkDataArray.o The compilation process does not stop, but the ignored lines cause problems when programs get linked. i.e. the appropriate methods cannot be found. Does anyone know of a fix to or the cause of this problem.

As far is I know, this is not The Right Way(tm) if you want to add functionality in a generic fashion. This would mean that your class can only work on OpenGL targets. A better way would be to derive from vtkActor and also CONTAIN an instance of vtkActor as member that can be used to perform rendering. The contained vtkActor will specialise (due to the object factories) as per usual. > Ron Jerome > Institute for Chemical Process and > Environmental Technology > National Research Council Canada > 613-993-5346 > > > >-----Original Message----- > >From: Steffen Oeltze [mailto:Steffen.Oeltze@Student.Uni-Magdeburg.DE] > >Sent: Wednesday, October 09, 2002 6:00 AM > >To: Vtkusers (E-mail) > >Subject: [vtkusers] deriving my own class from vtkActor > > > > > >Dear VTK-users, > > > >I have tried to derive my own class from vtkActor using the following > >code: > > > >class FIB_TRACK : public vtkActor > >{ > >public: > > FIB_TRACK(double [3], double [3], bool); > > ~FIB_TRACK(); > >.... > >} > > > >For creating a new object I use: > > > >FIB_TRACK *newAct = new FIB_TRACK(seedpoint, dims, true); > > > >Then, I construct the rendering pipeline, add the actor to the > >renderer and render the window but nothing happens.

George, Are you using the latest driver for your graphics card? (See http://www.matrox.com/mga/support/drivers/latest/home.cfm ) I had a rendering problem a couple of months ago that was solved by updating my graphics driver, as did another reader of this list.

This is the way I use it: ren = vtkRenderer::New(); ren->setViewport(0.0, 0.0, 0.5, 1.0); The method is documented in the manpages, into the vtkVieport class. vtkRenderer inherits from it, but even in vtkViewport seems to be missing.

I need to blank out a portion of my Structured Grid (consisting of Voxels ). I used the following functions in class vtkStructuredGrid ... structGrid->BlankingOn(); for(int i=start; iBlankPoint(i); ... but nothing seems to happen when the image is rendered. (1) The blanked out portions still appear in the image (2) also when I try to find out the neighbours of the cells just on the boundary of the blanked region, they still appear as neighbours even though the some of them happen to be in the blanked region. For example, if in the 2x2 grid below, the points a, b, c, d, e, f are blanked out. Then the neighbours of cell 13 should be 12, 20, 9 and Null. The cell 'd' should not show up as one of its neighbours. When an isosurface is rendered, the blanked out cells should not be considered while checking for isosurface cells, but this does not happen. 18 19 20 21 22 23 24 11 12 13 d e f 17 7 8 9 a b c 10 0 1 2 3 4 5 6 Does anybody know a way of doing this ? What am I missing here ? Has anyone run into this problem before? Any help will be deeply appreciated. Thank you in advance.

Every time I run a vtk program from the testing tree, the amount of free system memory (as reported by top) reduces by a certain amount (about 1 MB for Mace.cxx or Mace.tcl). This memory is persistently lost and can only be reclaimed by restarting the system. Am I mistaken, or have others experienced the same problems?

If I explicitly say points.GetPointData().GetScalars().SetName("elevation") it still writes out 'scalars' as the name. Now, if I set the scalar name explicitly with the writer, it writes out 'elevation'. ie out.SetScalarsName("elevation") To further complicate things, if I add more arrays of scalar data with GetPointData().AddArray(myArray) it does not append not merely append the extra arrays when I write the structuredpoints object to file. It mix and matched the arrays. In one instance, with the additional arrays, elevation was written second in the file and the name showed up....so it is there, something is just not allowing it to write the name to the file when it shows up first in the file. To clarify all of this, it would appear that StructuredPointsWriter uses a default name 'scalars' for the first scalar written to file, unless explicitly set within the writer object. With additional arrays, it does not just append them on to the original pointdata, but alters the order (how/why?). Am I doing something incorrectly? This all seems pretty straightforward. As reference I am using java + vtk 4.0. Any thoughts? -chris From cnavarro at ncsa.uiuc.edu Wed Oct 9 14:29:30 2002 From: cnavarro at ncsa.uiuc.edu (Christopher M.

The long answer is: In the old days (VTK 3.2 and earlier), the arrays/attributes did not have names. The names were stored in vtkFieldData instead. Furthermore, vtkPointData and vtkCellData were not subclasses of vtkFieldData, instead they each had an associated vtkFieldData. This meant that the only way to associate a name with an array was to store it in field data. This is why the writers had and still have special methods to set the attribute names stored in the file and also why they use a default name for each attribute. The new VTK readers/writers we are developing will not have this problem.

Here's what you should check; Take a look at /usr/include/GL/gl.h on your systems. If it mentions "Mesa" at the top, you are using the wrong include files. To fix that, run the following commands: ln -sf /usr/share/doc/NVIDIA_GLX-1.0/include/GL/gl.h /usr/include/GL ln -sf /usr/share/doc/NVIDIA_GLX-1.0/include/GL/glx.h /usr/include/GL ln -sf /usr/share/doc/NVIDIA_GLX-1.0/include/GL/glxtokens.h /usr/include/GL Then rebuild Vtk (or at least recompile and rebuild all Vtk libraries that depend on OpenGL). The problem is that the nVidia RPMs don't install the correct header files by default. -- Rob -- [] Robert Belleman X Section Computational Science [] [] robbel@science.uva.nl |X| University of Amsterdam, the Netherlands [] [] tel: (+31) 20 525 7510 X http://www.science.uva.nl/~robbel/ [] On Wed, Oct 09, 2002 at 03:20:15PM +0200, Thomas Koninckx Local wrote: > Hi, > > I've got a weird display problem.

I will answer to my own question :) I checked Suse web site, this Linux distrib comes with Tcl/Tk 8.4. CMake won't support it until you use the CVS version.

As soon as Execute I am getting error as ?Memory can?t be assigned error? I debugged the code it is stopping at vtkIdList.h // Description: // Reset to an empty state. void Reset() {this->NumberOfIds = 0;}; */ 2. Is there any vtk class, which I can use for collision avoidance? Basically I have two STL files and I want to check the collision around a particular point.

Rainer, if you are willing to experiment, we can try the following. Keep using VTK 4.0, and your current CMake (is it a release ?) and try any of those: a) edit the top VTK/CMakeList.txt file and add *at the top*: ADD_DEFINITIONS( -DUSE_NON_CONST -DUSE_COMPOSITELESS_PHOTO_PUT_BLOCK ) or the less intrusive b) Run your favorite CMake cache editor (i.e. CMakeSetup, or ccmake), show the advanced values, and add the above flags to any of those (if they exist): CMAKE_CXX_FLAGS CMAKE_C_FLAGS Thus, your CMAKE_CXX_FLAGS will probably look like: -g -O2 -DUSE_NON_CONST -DUSE_COMPOSITELESS_PHOTO_PUT_BLOCK Keep me posted if any of those work -- Sebastien Barre From eric at ece.gatech.edu Thu Oct 10 10:52:27 2002 From: eric at ece.gatech.edu (Eric Pichon) Date: Mon May 24 19:15:55 2004 Subject: [vtkusers] small objects are not rendered Message-ID: Hi All, When trying to render many objects, VTK will discard those that are too small and too far (even though they are still much bigger than one pixel).

I have run into a similar problem with older versions of Mesa in the past. It is possible that the OpenGL library distributed with Sun drops small objects when rendering. I would recommend compiling Mesa 3.5 and using it instead of OpenGL to test whether this is the case. -Berk On Thu, 2002-10-10 at 10:52, Eric Pichon wrote: > Hi All, > > When trying to render many objects, VTK will discard those that are too > small and too far (even though they are still much bigger than one pixel). > > I understand that this makes sense in many cases but it is a problem for > what I want to do (basically rendering hundreds of small spheres) and I > did not manage to get VTK to render all the actors regardless of any > optimization consideration. > > I set manually the clipping planes of the camera and I am not using > vtkLODactors but regular vtkActors. > > Your help would be greatly appreciated ! > > Eric Pichon > > --- > > I am using VTK 4.0 on a Sun Ultra 80 (SunOS 5.7 sun4u sparc SUNW) > > It was compiled using gcc version 2.95.2. > > At startup VTK says : > Using: /usr/openwin/platform/SUNW,Ultra-80/lib/GL/oglSUNWcore.so.4 > Using: /usr/openwin/platform/SUNW,Ultra-80/lib/GL/libvis.so.1 > > _______________________________________________ > This is the private VTK discussion list. > Please keep messages on-topic.

I'm working here in the Macromolecular Structure Group at UCSF (San Francisco) and I recently discovered MayaVI - Very nice program !! Since our data sets (optical and electronical microscopy data stacks) are rather "fuzzy" we would prefer volume rendering over surface rendering. 1) Are there new modules being implemented for mayavi ? Maybe "Volume Rendering" ;-) I read the documentation for mayavi and thought it shouldn't be that hard to convert e.g. the iso-surface module into a volume rendering module, since VTK supports both equally well, right? 2) I'm just curious how the "scalar cut plane" is implemented? Doesn't it convert the viewed data into a 2D-texture and is therefore an "identical" view of what a "standard" z-section view looks like (if the cut-plane is perpendicular to the z-axis, of course) ? 3) How do I change the used look-up table? I realized that a vtk-file contains a line that reads "LOOKUP_TABLE default" - what else is there besides "default" ? Also the mayavi example directory contains a ".lut" file - how do I use that? Thanks again for the nice work?

These variables were used in some of the functions in the parent class that I wanted to use. Since I use vtk3.2, I dont know what are the variables in vtkActor class that need initialization in vtk4.0 [The following is an overkill, but it is just another way of doing things - (the disadvantages of doing it are having to re-run config , making changes to lib, and possible memory leaks - not sure - there are probably better ways- if at all nothing, someone will point to simpler way to you after seeing my elaborate mail :)) ). (1) put the additional function, eg., fun1() , that you wish to have in your derived class as a Virtual function in the vtkActor class. (2) then, define the fun1() in the derived class to do what you want it to do. (3) define the New() function in your derived class. (4) in your derived class constructor call the vtkActor() contstructor with appropriate values for intializing any variables in the class - this will properly instantiate any vtkActor class variables. (5) you probably already have a destructor for your derived class in place. (5) for destroying instances of your derived class, call the Delete() method ( since u created the derived class using the New() method in vtk). It should ( probably not cause any mem leaks :) ) call delete() of vtkActor class and then finally delete your class instance too. (6) in the Makefile.in of the appropriate directory, add vtkActor to the list of Abstract classes (7) add your derived class to the list of Concrete classes (8) SAVE all other files that you have changed and your own files to a different dir. (9) re-run config with your own options and make to integrate your class into the library. ] good luck ! cheers, Joseph. --- vtkusers-request@public.kitware.com wrote: > Send vtkusers mailing list submissions to > vtkusers@public.kitware.com > > To subscribe or unsubscribe via the World Wide Web, > visit > http://public.kitware.com/mailman/listinfo/vtkusers > or, via email, send a message with subject or body > 'help' to > vtkusers-request@public.kitware.com > > You can reach the person managing the list at > vtkusers-admin@public.kitware.com > > When replying, please edit your Subject line so it > is more specific > than "Re: Contents of vtkusers digest..." > > > Subject: RE: [vtkusers] deriving my own class from > vtkActor > From: "Charl P.

Even though I have the feeling that on a different computer where we have a NVidia GForce4 Ti video card installed the corresponding sample (with 2D texture, I think) runs maybe faster !? The computer with the volumepro board has no hardware OpenGL support (yet). Would that help ? My understanding was that the VolumePro board works with a "different scheme" anyway.

Basically, the rendering program has an input which changes over time, and that input is plugged into a vtkProgrammableGlyphFilter which is then plugged into a renderer. When I initialize the source, everything is fine and dandy, but when I add elements onto the source (with the same 'old' elements in the source), they don't get displayed. I suspect that this is something to do with an UpdateExtent not being right, although I lack experience in this area. Anyone have any ideas? Thanks in advance Nate From nsmith5 at gl.umbc.edu Thu Oct 10 20:58:09 2002 From: nsmith5 at gl.umbc.edu (Nathan Smith) Date: Mon May 24 19:15:55 2004 Subject: [vtkusers] Problem with updating In-Reply-To: Message-ID: Lemme rephrase this because I narrowed down the problem: I do: set vtk(glypher) [vtkProgrammableGlyphFilter renderer] $vtk(glypher) SetGlyphMethod glypherProc After the data is updated, I checked vtk(glypher) right before any implicit calls to glypherProc, and it contained the right number of source points (7). But glypherProc is only called 4 times (the previous number of source points). So something between the renderwindow and renderer and glypherProc is not noticing that there is an updated source. Anyone know where this could lie?

(You may also need to do a STLReader->Update() before the call to BuildLocator.) For collision detection a thorough approach would be to tetrahedralize if necessary all your objects so they are represented as solids (not just as surface meshes) and then use vtkCellLocator::FindClosestPoint to detect if each point is inside a cell. Good luck, Tim. At 14:17 10/10/2002 +0100, Mysore Siddu wrote: > Hi vtk Users, > > I have two questions: > > > >1.

With windows there is no problem, but with linux there is an error in the libX11.so. in attachement there is a sample application who reproduce this problem, in the class MySimpleVTk, there is this code //here works //panel.addView(v); frame.pack(); frame.setVisible(true); //here doesn't work panel.addView(v); if i change the order of these instructions, the application work or not. if someone can try this and at least say me if he has the same behaviour. it can help me.

I hope that the result is explained by the examples that are available at http://www.civil.ist.utl.pt/~moitinho/vtk The behaviour of the object is controlled by two new Boolean variables ThreeGlyphs and Symmetric. When they are false the object behaves as vtkTensorGlyph. If ThreeGlyphs is true three glyphs, which are scaled according to the eigenvalue along the main axis (the one that after rotation corresponds to the eigenvector), are drawn. If Symmetric is true then the glyph (or the glyphs) is/are mirrored, i.e. 2 or 6 glyphs are produced. In the examples both variables are true. This behaviour is usefull in solid mechan
