Hi vtkGurus

I am using vtk(cvs) with Java on Windows XP platform.  I = also use vtkPanel, I want to be able to write my scene to a tiff format image using the = usual vtkWindowToImageFilter and then vtkTiffWriter

So far so good, but with vtkPanel I can not do the = following

w2if.SetInput(renWin3D);

because renWin3D is not actually a = vtkRenderWindow, its vtkPanel

Is there anyway, I can get around this problem in java

Thanks

Message-ID: <000a01c238e8$e39e84a0$73b25a99@ALEXWORKSTATION> Hello, I have about 1000 actors that make up a branch structure. As I zoom away from them they seem to disappear depending on their size. It doesn't seem to be a clipping issue because they don't seem to disappear depending on placement but by size. If someone knows how to stop this disappearing I would like to know. I have made a movie of this and posted it at http://www.eotbat.com/Branch_Dissolve.avi . It is a little under 5MB. Sorry about the size but it needed to be large and good quality to see this problem.

Message-ID: Hi Alex, I just can't resist a good movie... Is this a lighting effect? The branches seem to become increasingly shaded until they merge with the black background. Have you set up a positioned light source instead of the default 'headlight'? Would a white background clarify if black shading is making the branches disappear? The branch size effect may be due to resolution in the shading calculations. As you zoom out, a branch surface decreases towards being a just pixel or so wide 'on-screen', and its averaged surface normal may point further and further away from the camera. just guessing, Dave Pont "Alex Lear" To: "vtk users" Sent by: cc: vtkusers-admin@public.k Subject: [vtkusers] Actors disappearing on zoom - Video! itware.com 01/08/2002 11:20 Hello, I have about 1000 actors that make up a branch structure.

Add all terms, and put the sums in a symmetric 3 by 3 matrix (xx,xy,xz; xy,yy,yz; xz,yz,zz). This matrix represents an ellipsoid whose shape corresponds with the shape of your points. From this matrix you can calculate the eigenvalues and eigenvectors (see vtkMath). These eigenvectors and eigenvalues define the directions and lengths of the main axes of this ellipsoid. The vectors belonging to the largest eigenvalues give you the orientation of the requested plane. The position of the plane is determined by the centriod of your points.

Or is there any description in the net? The read me files I found in the distribution did not help a lot... When I tried to run a vtk example script, I got the error message tcl833.dll not found. To overcome this problem, I have copied all tcl/tk dlls into the win/syst folder. But after that I had to deal with the error message: tcl.ini not found ...inproper TCL installation. However TCL works fine. I use the Active Tcl 8.34 distribution on a Win98 PC. A couple of years ago, I used vtk 2.2. The installation wasn't a problem at all. I just had to unzip the given executable ... However, I would be happy about any kind of help ...

The patented code is not included in the binary distribution. To get that you have to recompile VTK yourself. Instructions for doing that can be found in the VTK books.

Digging in the code, I see: for ( ptId = this->Offset; (ptId < numPts) && (id < (this->MaximumNumberOfPoints-1)) && !abort; ptId += this->OnRatio ) The part that fails is "id < (this->MaximumNumberOfPoints-1)" since id is 0 and this->MaximumNumberOfPoints-1 is zero, it never falls in the loop. Changing it to a <= doesn't work for values > 1. I added a : if (this->MaximumNumberOfPoints == 1) { x = input->GetPoint(this->Offset); id = newPts->InsertNextPoint(x); outputPD->CopyData(pd,this->Offset,id); } else above it, but this may not be the best fix since there may be a way to handle the random case and the non-random case in the same way. If you need a test case, the Examples/VisualizationAlgorithms/Tcl/spikeF.tcl exhibits the problem if you add a ptMask SetMaximumNumberOfPoints 1 in there.

I use IB to combine AND transform several implicitfunctions. However, the transform doesn't seem to be working. Running debugger (ddd) I noticed that the ImplicitBoolean::EvaluateFunction(x) doesn't use the IB transformation. I would expect xt = IB->Transform(x) and then f = IF(xt) whereas it now directly calls f = IF(x) avoiding the transformation. Hope somebody can shine a light on this one.

Implicit boolean is a subclass of the = more general Implicit function which defines the transform and it just = got left out.

Once you create your PolyData you can associate point scalars with the points of the data. Create a vtkFloatArray and then stick the scalars in it and then associate this array with your point data. Thats about all you need. pd = vtkPolyData() # this is your polydata object. You might generate it some other way. sc = vtkFloatArray() for i in range(pd.GetNumberOfPoints()): sc.InsertNextValue(_insert_your_scalar_here) pd.GetPointData().SetScalars(sc) cheers, prabhu From nundys@neuro.duke.edu Tue Aug 6 16:43:28 2002 From: nundys@neuro.duke.edu (Surajit Nundy) Date: Tue, 06 Aug 2002 11:43:28 -0400 Subject: [vtkusers] Accessing Arrays in Matlab-Java-vtk References: Message-ID: <3D4FEEA0.4050602@neuro.duke.edu> Is it possible to access a vtk array from matlab (such as vtkFloatArray or vtkUnsignedCharArray).

Is there an I assume you mean "voxel" color/texture. > easy way to texture the isosurface from the first set with the information > from the 2nd set? You can use 3D texture mapping (depending on the platform you are running this on, it might or might not be available) to create a 3D texture from the second volume and apply it to the isosurface from the first. This will work even if your isosurface (isovalue) from the first volume changes. An alternative would be to extract the texture/color values from the second volume for each vertex of the isosurface and render the triangles using the per-vertex information. If your isosurface changes however, you will need to re-compute the above.

First check if your machine supports 3D texture mapping using the following command - % glxinfo | grep EXT_texture3D If yes, you can do this directly using OpenGL... see man glTexImage3d, glTexParameter, glTexGen. If not, use the other method of computing the per-vertex color values from the second volume and render the isosurface using those values. hth, Praveen -- ----------------------------------------------------------------- Praveen Bhaniramka Member of Technical Staff (MTS) praveenb@sgi.com Advanced Graphics Division (650)933-1785 Silicon Graphics, Inc. ----------------------------------------------------------------- From david.netherway@adelaide.edu.au Fri Aug 9 02:08:37 2002 From: david.netherway@adelaide.edu.au (David Netherway) Date: Fri, 9 Aug 2002 10:38:37 +0930 Subject: [vtkusers] memory allocation limit in windows 2000 or vtk ?

The surface is a northern hemisphere cut by an arbitrary plane. The points that are triangulated are the union of points on a sphere (generated using something like Glyph) and a set of boundary points (from the intersection of a sphere and a given plane). I am using Delaunay2D to triangulate this set of points using the following code: // Read points from file vtkPoints *points = vtkPoints::New(); fscanf( inhandle, "%d \n", &max ); xyz = ( double * )malloc( 3*max*sizeof( double ) ); for( i=0; iInsertPoint( i, &xyz[3*i] ); } // Specify constraints npts=5; // Varying this changes the surface appearance vtkCellArray *line = vtkCellArray::New(); for( i=0; iInsertNextCell(2); line->InsertCellPoint( pts[i] ); line->InsertCellPoint( pts[i+1] ); } vtkPolyData *profile = vtkPolyData::New(); profile->SetPoints( points ); profile->SetLines( line ); vtkDelaunay2D *del = vtkDelaunay2D::New(); del->SetInput( profile ); del->SetSource( profile ); del->SetTolerance( 0.0 ); del->SetAlpha( 0.0 ); del->BoundingTriangulationOff(); del->Update(); What I find wierd is that the surface appeareance changes depending on how many edges along the cut I specify as constraints. This problem appeared once for a particular case where the cutting plane slices a small part of hemisphere making a small angle with the equatorial plane. Depending on the number of specified edges I was getting either a correct surface or pieces of surface close to the polar cap.I also tried to change the scheme for generation surface points, but it did not change things. I am in a dire need for some advise. Does my code look Ok for this operation? Is it possible that I am encountering some vtkDelaunay bug? So far, I noticed this kind of problem only once among few dozen cases that I looked at. I would be glad to provide full code and data set which is resulting in this behavior. Any comments/advises would be greately appreciated. - Alex Smondyrev. __________________________________________________ Do You Yahoo!?

Windows 2000

Borland C++ 5.5.1 for Win32, using dos prompt
CMake 1.4.3-patch (has the same errors as CMake 1.3 development)

I got past this error by editing the Make files. Not an elegant solution but I could live with it if I have to. Requires 8-10 files to be edited.

THE SHOW STOPPER IS AN UNRESOLVED EXTERN SYMBOL IN THE IO DIRECTORY FILES. Sorry lost the error but will re generate it if someone in the borland community can help me.

Does anyone know of a freely available volume rendering program based on vtk (preferably small and with source - just to get an idea of how things are done)? I had a look at the vr examples and was quite amazed by the LOD features, but the examples are just too simple.

In C++, you do not have direct access to protected variables outside of the class they are in. You only have access to them if methods are provided in the public section that allow you to get or set their values.

I've added interactivity such that the user can manipulate the view of the actors in the window. Another feature is saving images into a file (.bmp, .jpg,...). For the saving procedure, I'm using vtkWindowToImageFilter and the standard writers, say vtkBMPWriter. The problem here is that after saving an image, the interactivity performance drops. The view manipulation turns very slow. I made sure of deleting the filter and the writer after the file is saved but it doesn't solve the problem. It is my guess that in the pipeline, the window is still sending data somewhere. I've also noticed that this problem only affects the performance of the saved window. If there are more windows present, the others will behave normally. Hence, a possible workaround would be creating a temporal copy of the window just before saving. DeepCopy() should do but it's not implemented in all classes. Any help would be appreciated. Christian Chilan __________________________________________________ Do You Yahoo!?

Message-ID: Good tip Ken, but I already encountered that problem way back when I first started on this app, (on my old machine). I just tested this out again with a large image and yes I can get a white rectangle (at any level of graphics acceleration) if the image exceeds my machines maximum texture dimension. This is reported as 1024 using the following: long maxDimGL; glGetIntegerv(GL_MAX_TEXTURE_SIZE,&maxDimGL); So image size is a gotcha, but given I have images below the maximum size, I still get a white rectangle unless I 'dumb down' my graphics acceleration. I even tried a tiny image (19*32) to be sure. Yesterday I got the latest drivers from NVIDIA, but this made no difference. I have a work-around, but I am still baffled that a modern graphics card has to be crippled to support texturing in OpenGL. I kind of feel it should be solvable. Is it because graphics cards are optimised for DirectX, leaving OpenGL out in the cold? is it because there are too many combinations of hardware / software to ensure all work? should I upgrade to vtk 4? can I update my OpenGL? are there some little-known Windows/NVIDIA/OpenGL/vtk settings I can twiddle? is it a hole that is too deep and dark for sane people to go into?

Date: Wed, 14 Aug 2002 15:30:20 -0400 Subject: [vtkusers] Texture not displayed (NVIDIA problem?) Message-ID: <27A3FCA5E1CFD1119718000629B00EB40BBBF608@sbyexc01.kpgraphics.com> Hi, I've run into a similar problem to this on my IBM T23 laptop, which has an S3 graphics chip. I have checked and do have the latest available driver loaded on my system. In my case, I can render the object to the screen (set up using SetScalarModeToDefault() in the mapper) and it will come up in color, but as soon as I click the mouse in the window to rotate it, it turns white. If I re-call SetScalarModeToDefault(), the object color will be back (until I click in the window again). If I map the color differently (using SetScalarModeToUsePointFieldData() and ColorByArrayComponent() in the mapper), it maintains it's color as I rotate. If I set the Hardware Acceleration for the display down to the next to the bottom setting, this problem goes away -- the object will rotate in color without changing to white. In checking this out further, I've come up with a simple example that exhibits the problem. I built the "SampleMFC" project from Examples\GUI\Win32, and made a sample data file. Opening the data file with the "Win32SampleMFC.exe" that is generated from this project gives the same behavior -- the object (a simple cube in the test file) opens as color, but changes to white as soon as I click to rotate. If I close the window and re-open the file, it again comes up initially in color. This was tried with both the vtk 4.0 Release and vtk 4.x Nightly distributions. The data file is the following: # vtk DataFile Version 2.0 Test Cube ASCII DATASET POLYDATA POINTS 8 float 0.0 0.0 0.0 1.0 0.0 0.0 1.0 1.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 1.0 0.0 1.0 1.0 1.0 1.0 0.0 1.0 1.0 POLYGONS 6 30 4 0 1 2 3 4 4 5 6 7 4 0 1 5 4 4 2 3 7 6 4 0 4 7 3 4 1 2 6 5 POINT_DATA 8 COLOR_SCALARS vertexColors 3 0.0 0.0 0.0 1.0 0.0 0.0 1.0 1.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 1.0 0.0 1.0 1.0 1.0 1.0 0.0 1.0 1.0 So, it seems that something is being set differently when the window is first rendered than when the window is updated as the object is being rotated. Any ideas or suggestions are welcome.

I want to show each surface with a different color. If I introduce the surface in a 3D matrix (a 3D image) and I apply marching cubes to smooth the surface the results are very bad (the surface appears in pieces) because it expects a volume as input. So I build a volume (the cortex) and the marching cubes produces a nice surface, but the two surfaces at the same time and with the same color. How can I do it then? Is there in vtk a function that creates a smooth surface from points (similar to vtkLine for lines)?

You do not need the rendering subsystem. Just create the pipeline as usual and leave off the mappers, actors, and other rendering stuff. Manually invoke Update() method on the last filter of each pipeline to cause the pipelines to execute. If the last filter is a Writer, invoke the Write() method.

No, you are right, until recently LineSpacing (as well as LineOffset actually) were not really supported. This has been fixed recently (some weeks ago) when the new unified text mapper has been setup. You will need to download the development distrib (VTK CVS).

The color components are independently clamped to 1. Your scalar color may be 1.0, 0.1, 0.1 (mostly red) but due to the lighting parameters the shaded value may be 5.0, 0.5, 0.5 - which will be displayed as 1.0, 0.5, 0.5 (a much more washed out red). Try adjusting your ambient / diffuse / specular coefficients so that they do not add up to much more than 1.0.

Try using vtkPolyData. You can create any number of seperate lines all feeding into the same actor. If you want to color parts of the same actor differently, you're going to have to use scalar values. You can create a color map with each of the colors that you want to use, then assign appropriate scalar values to each point on the lines to get them colored properly. For example, if you wanted all of your lines to be either red, green or blue. You could create a color map with three entries, configure the mapper to have a min of 1 and a max of 3, then each point on a red line could be given a scalar value of one, green lines 2, and blue 3. That would do it I think. Kevin.

Changes to mouse use are: 1) left button does cross-hair cursoring: the cross-hairs snap to slice plane pixel centres. The code to do this is substantially different from what was there before: it seems to work for most oblique slice orientations I have tried. If anyone can show me a better (more accurate) way to do this I would be grateful. 2) middle mouse button does pushing, spinning and rotating. There are now invisible 'margins' on the slice plane: currently 5% of the in-plane x and y dimensions. Picking on the left or right margin rotates the plane around the local y prime axis. Similarly, picking on the top or bottom margin rotates the plane around the local x prime axis. Picking one of the four corners of the plane spins the plane around it's normal. Picking inside of the margins does a standard push along the current plane normal. 3) right button does window/level. Any thoughts or criticisms are always welcome ... enjoy!

as i presented some simple VTK stuff to my collegues in the projectgroup the program crashes with Segmentation Fault when I switch between Track and Joystick – Mode. The VTK Program shows 3 Cylinders, 3 Cones and 4 spheres, so not even complex stuff. Does anyone knows how to work around that issue or is it a known bug?

The vtkImageViewer always maps one image pixel (voxel) to one screen pixel i.e. it ignores the Spacing of the image data. The vtkVolume does look at the Spacing of the input image data, so it will see that the spacing in Z is on-fifth the spacing in x or y and render accordingly. When you read image data into VTK, you should always make sure that you set the x, y, and z spacing correctly in the Reader. For example to something like (1,1,5) in your case. Then, to you resample the data, you change the spacing to (1,1,1). There are many filters in VTK that cant't work properly unless you correctly set the DataSpacing in the Reader. These include vtkImageReslice, vtkMarchingCubes, vtkContourFilter, vtkProbeFilter, vtkImageActor and several others. - David -- David Gobbi, MSc dgobbi@imaging.robarts.ca Advanced Imaging Research Group Robarts Research Institute, University of Western Ontario On Mon, 19 Aug 2002, Yuan Jin wrote: > Hi all, > > I am trying to get more slices from the raw data, ie. interpolate between > two adjacent slices to generate more slices.

So, try moving the mouse left to right until level is around the center value of your data set, then adjust window to the desired level of contrast.

I knew already how to do this but there is a slight problem. The level and window values don't have the right values compared to the values in my data. My data ranges from 500-1500 And the maximum window and level values are +/- 3, even when I move the mouse in the direcion of the maximum level and window values. So is there a bug in the widget or am I forgetting something. So my problem is that the window, level values don't scale with my data.

We've used VTK and related software to visualize LSM510 volumes, though using Windows boxes, for a couple of years with very good results. The = .lsm file format is available from Zeiss, so that if you want to read in the = data directly you can generate a reader. I've written a simple, limited = .lsm file reader for an application that we use in-house - I'm not much of a programmer, but I'll clip out the relevant parts and send them if you promise not to laugh in public. Alternatively, the LSM510 software can export single-channel data to a series of .tifs, and VTK includes a = TIFF file reader that may be able to handle these files relatively easily. You'll have to enter spacing, wavelength, etc., manually if you go the = .tif route. If you're not interested in writing the code, then I highly recommend VolView from Kitware, which does run in Linux, and does handle the LSM510-output .tifs. We've been using VolView for a year or more and = have a number of labs that use it regularly. We have not tried to use stereo-viewing hardware, so I can't address that part of your question. = If you can afford it, I would highly recommend getting a VolumePro board = from TeraRecon (don't know if it works in Linux) which allows very rapid = zooming, rotating, etc. with large datasets.

If your CT data has nice borders in it, then you could use marching cubes to create the surface and then write an STL file (triangles) which most CAD packages can read, however in my experience what the CAD folks are looking for are NURBS type surfaces which I've not seen generated in vtk. Some CAD packages can drape NURBS surfaces on poly meshes but I've not had much luck with that personally. I've not seen any meshing capabilities for FEA but I might be wrong here since I'm not real familiar with FEA. I'm fairly sure you can represent tets and hex volume meshes in vtk but how to do this from the CT data and whether these would be suitable for FEA I'm not sure. My coworkers tell me FEA meshing can be tricky business. It is possible that I've missed some classes or that there are vtk user generated classes out there that can handle these issues. Perhaps a search of the archives might turn something up. I hope folks can prove me wrong on a number of these statements as I'm looking for some of these capabilities myself.......john Internet Mail Message Received from host: public.kitware.com [24.97.130.19] From: "Ng Hong Wan" @public.kitware.com on 08/20/2002 02:07 PM ZE8 "Ng Hong Wan" To: @public.kitware.com Cc: (bcc: John Anast-JM/PGI) Subject: [vtkusers] CT - VOLUME - CAD Sent by: vtkusers-admin@public.kitware.com 08/20/2002 02:07 AM Hi, Is there a known approach to reconstruct a 3D volume model from CT using VTKand import it successfully into well known CAD modelers like Unigraphics, Pro E, AutoCAD If not What abt a known approach toreconstruct a 3D volume model from CTusing VTKand import it successfully into well knownFEA software like ABAQUS, ANSYS, NASTRAN.

In my lookuptable I want "direction" to determine the Hue and "velocity" to determine the Value independently. Is it possibile to do that and how? Or is there any other way to assign color to a point in the polydata other than using scalar and lookuptable? Thank you for your help!

I thought the import vtk.*; and System.loadLibrary() should get me beyond >this point, but I must be missing something! Compiler error suggests that you do not have vtkConeSource in your classpath. A strange thing is that must have something in from 'vtk' otherwise you will get compilation error at 'import vtk.*;' Verify the classpath you program is seeing by adding following to your code: System.out.println("classpath="+System.getProperty("java.class.path")); And rerun you code. If you do not see vtk.jar in the classpath. Then that is what you are missing. Add it and ignore rest of this message :) If you see vtk.jar in the classpath then since you did not get compilation error at 'import vtk.*;' chances are that you have an incomplete vtk.jar. Check if you have vtkConeSource in subdirectory vtk in the vtk.jar (You can open a jar file with JBuilder, that is probably the easiest way. You can also with WinZip or using command prompt 'jar -tvf vtk.jar').

Message-ID: Hi again, the simplest answer is you can't do this. Widgets, in general, maintain one or more actor instances, one or more picker instances, and a reference to a render window's vtkRenderWindowInteractor. The widgets 'listen' to the interactor's events and then respond to some of them (e.g., left mouse click) if the widget's picker determines that one of its internal actors has been picked. In the case of vtkImagePlaneWidget, zooming/rotating/translating is applied to all actors in a render window (not just the widget) via its render window interactor: in fact, zooming and translating are not internal capabilities of the widget. If what you want is to see one slice of a plane of data obtained through the vtkImagePlaneWidget, have a look at the code in /Hybrid/Testing/Cxx/ImagePlaneWidget.cxx: you can turn off the xy-plane widget (planeWidgetZ) and the output form the widget's internal vtkImageReslice remains in the second renderer.

There are now visible 'margins' on the slice plane: currently 5% of the in-plane x and y dimensions. Picking on the left or right margin rotates the plane around the local y-prime axis at plane centre. Similarly, picking on the top or bottom margin rotates the plane around the local x-prime axis at plane centre. Picking one of the four corners of the plane spins the plane around it's normal. Picking inside of the margins does a standard push along the current plane normal. ... AND NOW ... Holding the shift key and middle mouse picking the plane activates uniform scaling: mouse move up enlarges the plane while downwards shrinks it. Holding the control key and middle mouse picking the plane activates plane edge translation depending on which area of the margins is selected: 1) corners: edges that intersect at a corner are translated 2) edges: edges are translated 3) middle: whole plane is translated 1) and 2) are a really form of constrained 'scaling'. enjoy...

In fact I am running with vtk 3.1 (legacy app that I dont want to disturb) and UnregisterAllOutputs is not available. Further, after peeking at the latest code from the vtk CVS, I could not figure out how to get the same effect in 3.1 with public methods. So I connected my TIFFReader to a temp instance of vtkImageData, called Update, then copied its contents 'manually' (DeepCopy with some other bits) to a permanent vtkImageData (one per image) which acts as the start of my official pipeline. This effectively disconnected the TIFFReader from the pipeline, allowing me to delete it after input. Maybe there is a smarter way? I still dont fully understand all the workings of reference counting, although I learnt a bit more. I am not sure if using a volume approach would help with the file handle issue? Also, as my slices are not of regular spacing or size, and require individual transformations (rotation, translation) the only benefit of a volume (apart from one-shot input) would be as a handy 'array' for my set of slices. Still it is food for thought, I have never worked with volumes so that limits my ability to see how they could be useful... wheres my vtk book....

I don't know if this is deliberate (so that you can tell when a file is changed and reload) or a bug. But if the same applies to a tiffreader, then your max files problem will manifest. loop over all 80 If you vtkTiffReader->Update() then mytiff[loop] = vtkTiffReader->GetOutput(); mytiff[loop]->Register(NULL); vtkTiffReader->UnregisterAllOutputs() vtkTiffReader->Delete() end loop the files should be closed after each read and you won't get the trouble.

My poit is that prebuild binaries for Windows are broken. vtkNightlyJava.exe does not include Java class binaries. It is not possible to correctly install VTK Java bindings from current/recent vtkNightlyJava.exe. You are absolutely correct about building Java binding from source. Building from source gives you number of advantages, however, it requires time, specific knowledge of setting up and running build environment, and reasonably fast machine. Building from source is not something a typical end user would be able or willing to do. One of my ideas was to provide a plugins to access some of the VTK functionality from ImageJ (http://sourceforge.net/projects/ij-plugins/). In particular some functionality, like vtkImagePlaneWidget, that is not available in VTK 4.0 release (Java bindings install perfectly fine here for this release). Nighlty binaries provide a convenient way get recent release without a need of going through a trouble of compiling. It is great that VTK folks provide this convenience. I am just trying to point out to Nightly Maintainers that one piece is broken to the point it that is cannot be used at all.

I'm developing a volume-rendering tool using normal CT images.
In the VTK UserˇŻs Guide, Ray Casting method is described in detail but 2D texture mapping approach is not good.

I use ˇ°vtkVolumeTextureMapper2Dˇ± in Visual C++.
When I got the result, the rendered image is so slow to show in different directions.
If I make it fast, what functions do I use?
I want to add some color displaying 3D images. How can I do?
In addition, IˇŻm just beginner in vtk so any functions will be great for me.

If it is possible, attach sample C++ code.
Hope to your prompt reply :)

Message-ID: <3D650E34.13724.189B204@localhost> hi, vtkusers, I compiled the vtk4.0 with the option to tcl successfully. And I can run my own vtk c++ applications. But I can not run tcl examples. When I run tcl examples, the message " can't find package vtk while executing "package require vtk" " always appeared. Does anyone know how to solve this problem? Thank you very much.

Every volume is different it seems so defining the values can take some work. Most programs use interactive adjustment of the point position and value to get it right, however there is not a standard "interactor" implemented in vtk. I've always wished for a vtkTransferFunctionWidget! In tcl you can hook up some simple sliders to change the values but its a bit of a pain and not as flexible as sliding points and values around on a graph. I've had in the back of my mind to build an interface in tcl by picking/moving points in a 2D render window but haven't got to it yet. To see a nice implementation of interactivity in the setup of the opacity, color and gradient transfer functions download the trial version of VolView from the Kitware web site. Certainly examining the histogram range and shape could lead to to some good estimates of the transfer functions but its typically non-linear and would take some extra work to get it just right. (I think transfer functions are like art, a matter of taste to some)...certainly possible though. It all really depends on what you want to emphasize, which is why this is often done interactively......john Internet Mail Message Received from host: public.kitware.com [24.97.130.19] From: "Yuan Jin" @public.kitware.com on 08/22/2002 01:47 AM GMT "Yuan Jin" To: vtkusers@public.kitware.com @public.kitware.com Cc: (bcc: John Anast-JM/PGI) Subject: [vtkusers] Piecewise Function for Volume Rendering Sent by: vtkusers-admin@public.kitware.com 08/21/2002 09:47 PM Hi all, Does anyone have experience in setting up the piecewise function for the volume rendering? ie. which points should be added to the piecewise function? Is the histogram for the 3D image helpful? For instance, in the example: VolCutKnee.py white_tfun = vtkPiecewiseFunction() white_tfun.AddPoint(0,1.0) white_tfun.AddPoint(255,1.0) tfun = vtkPiecewiseFunction() tfun.AddPoint(70,0.0) tfun.AddPoint(80,1.0) vol_prop = vtkVolumeProperty() vol_prop.SetColor(white_tfun) vol_prop.SetScalarOpacity(tfun) How to find out tfun.AddPoint(70,0.0) and tfun.AddPoint(80,1.0) ?

I ran into the following problem: --- vtkPiecewiseFunction f f AddPoint 0 0 f AddPoint 1.00000000000000001 0; # ridiculus, isn't it? f AddPoint 2.000001 0; # This happened in a real case f AddPoint 3.00001 0 f AddPoint 4 0 f GetRange (--> 0 4) f RemovePoint 0 f GetRange (--> 1 4, so 1.000000[...]01 was rounded) f RemovePoint 1 f GetRange (--> 2 4, but 2.000001 wasn't rounded, see below) f RemovePoint 2 f GetRange (--> 2 4, still there) f RemovePoint 2.000001 f GetRange (--> 3.00001 4, no rounding) --- Is there another way to get the defining values from a vtkPiecewiseFunction than that? The GetDataPointer Method isn't wrapped... Thanks, Ben -- There are only 10 types of people in this world: Those who understand binary, and those who don't.

All objects are cubes, with per-object color and per-object opacity and they are long and thin sometimes. Problem was that when rotating/zooming around/into the data the rendering was no longer correct but objects from behind "jumped" into the foreground. This occured when opacity was set near to 1. Several solutions were proposed: DepthSortPolyData does not work for long thin primitives and just for one transparent object. Sorting the objects backtTofront and rendering in this order did not solve the whole problem, just brought little improvement, cause there is no occlusion detection. Isn't there any (probably easy) way to achieve correct rendering of my scene?

a structured grid data set. I would like the color of the vector line to be scaled to the length of the vector, and not a particular scalar component of the vector. How do I pull this off? Various combinations of inputs to the vtkHedgehog or the polydatamapper have given solid colors, but not a color scale.

I'm working on a basic MRI slice viewer. I have an actor made up of a texture and a plane (256x256 resolution, scaled to 256x256). It's the only actor I have in the space. I want to click on it and get some kind of coordinate or point number that I can transform (if necessary) into an index into the 256x256 space regardless of the orientation of the plane (mainly so I can let the user pan and zoom). When I use vtkPointPicker this seems to work when the camera is at its initial setup but once I start interacting with the scene, it starts giving inconsistent picks. It seems as the picker doesn't know about the camera changes being made to the scene and is picking based on the original actor's location and camera setup. Here is the code I am using to set up the picker: set picker [vtkPointPicker _picker] $picker AddObserver EndPickEvent PickPointCB $picker SetTolerance 0.1 set interactor [vtkRenderWindowInteractor _interactor] $interactor SetRenderWindow $renderWindow $interactor SetPicker $picker bind $rwRender \ "$picker Pick %x %y 0 $renderer;" I can provide mroe code if necessary. I feel like there should be call to 'connect' a picker to the renderer or camera somehow, but none of the picker sample code I've seen seems to do this. Am I missing something? Thanks. -- Kevin Teich From glgraf@asu.edu Fri Aug 23 19:17:39 2002 From: glgraf@asu.edu (Gary L.

The result is a nice cube where different colors blend from corner to corner. Another example assigns the scalars using the vtkTuple1 (or 2 3, etc.). When I use this the coloration doesn't make sense. The documentation with regard to what the render does with those scalars is week. How are they interpreted. What does it do differently between single value scalars and multiple value scalars. What is the allowable range and what happens if out of range? These questions of course relate to the default rendering and not to cases where specific direction is applied.

I know the book is a few years old, but still a lot of us are using it and some
of us use it in visualization courses and for projects..

If you want to colour each line with one colour that is determined by its vector magnitude, you can use vtkGlyph3D.

It sounds like he wants the magnitude of the vector to control the color, but this is what vtkHedgehog does by default, from the docs. You have to work harder to get a component of the vector to be the scalars that are used to control the color. -- krs > > > > > Jess Neri > > I'm not sure if you want each line to have multiple colours (I don't know how > to do that). > > If you want to colour each line with one colour that is determined by its > vector magnitude, you can use vtkGlyph3D.

The source code is
(Visual C++)
// extract the skin
skinExtractor = vtkMarchingCubes::New();
skinExtractor->SetInput(v16->GetOutput());
skinExtractor->SetValue(0, 500);
skinMapper = vtkPolyDataMapper::New();
skinMapper->SetInput(skinExtractor->GetOutput());
skinMapper->ScalarVisibilityOff();
skin = vtkActor::New();
skin->SetMapper(skinMapper);

But when I compiled it, I failed..

Linking...
Win32Cone.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: void __thiscall vtkMarchingCubes::SetValue(int,float)" (__imp_?SetValue@vtkMarchingCubes@@QAEXHM@Z)

Debug/vtkwin32.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

WhatˇŻs the problemˇ¦?
I checked ˇ° skinExtractor->SetValue(0, 500); ˇ±
I think parameters are rightˇ¦
How can I correct the errors?
I donˇŻt understand the errors; unresolved externals.
I need your help~

I want to use vtk2.4 to practice examples.
I installed ˇ°vtk24cpp.exeˇ± from ftp://public.kitware.com/pub/vtk/vtk2.4/
In vtk40, CMake supports to make examples and I have experience it.
I think ˇ°pcmaker in vtk24 folderˇ± is the same as CMake, does it?

I want to make examples using pcmaker.
Please let me know the procedure.
I use Visual C++ 6.0.
How can I setup the options: directory, library?

In-Reply-To: <20020825103804.1C5111AB47@public.kitware.com> Message-ID: Hello, I was hoping someone could help me regarding thin plate spline transforms (code follows the end of this mail) I have two 3d models of a face, and a list of corresponding points on each model. I am trying to find the thin plate spline transform bewtween the two models, then pass it to the first model, to see if it will correctly produce the second model. However when I do this, the effect is as though I had 'steamrollered' the face - it becomes completely flattened, from the side on. Using the source landmarks as both source and target data produces an (unchanged) 3d image, so I dont know if its my dataset or the way I'm applying the warp at fault. Either way I think I've just misunderstood how to use the function. (I'm following the ThinPlateSpline example from the kitware man pages) If anyone has any suggestions as to where this is going wrong, I would be extremely grateful. Thanks!

If you use too many then the transform can crumple up. Make sure that the landmarks are placed correctly on the faces, and that their indices correspond. The code looks fine (assuming you actually do warp->SetTransform(tpst); ). Try with fewer landmarks to start with? (Eg. 9) Hope this helps, Tim.

As you know, the Vtk book has gone out of print. There are however
a number of universities out there (undersigned included) that teach
a scientific visualization class and use the Vtk book as part of
the material.

Why has the book gone out of print? Is there a new edition coming?
If so; when? If not; should we bug the publisher until we get them
to print again?

Message-ID: I have been working on setting up VTK to work more seamlessly with Project Builder and Interface Builder, so that Cocoa programmers can easily integrate it into their apps. So far I have been able to compile VTK in Jaguar, run the mace example from PB, and now create a vtkCocoaGLView subclass which can be used in Interface Builder like any other view class (ie. it can be contained inside a standard NSWindow, rather than requiring that the enclosing window be a vtkCocoaWindow.) I should also be able to build a VTK framework. I do have one problem though: when I interact with the Mace example by clicking and dragging, the Mace rotates, but the mouse events seem to be interpreted relative to an origin near the left-bottom corner of the screen, rather than relative to the center of the view. If I click in the view, and then drag the cursor to the bottom-left of the screen, the mace starts to rotate slowly, and even stops. I thought I would try the standard mace example from the command line, to see if this was a problem I introduced, but the same problem exists there. If you setup the Mace example to allow for interaction, run it, and then move the Mace window before click-dragging in the window, you can see that mouse events are interpreted relative to an origin near the left-bottom of the window, not the center of the window as they should. Does anyone know of this problem, or what could be causing it? Drew ======================================== Dr. Drew McCormack (Kmr. R153) Afd.

Previously I was using a games oriented graphics library for visualisation. I have now included a vtk MFC based window. However, I am finding that the simulation times have increased by 70-90%, despite the fact that the graphics functions aren't (I am pretty sure) called during the simulation (which runs on a separate thread). I am using the static version of the vtk libraries, compiled for Pentium Pro and mutilthread. Any ideas?? Yours in hope, Jim ______________________ James C.

Message-ID: <1030532132.1101.40.camel@maraca.cs.ucl.ac.uk> I am trying to visualize voxel data by creating a 3D volume of adjacent coloured cubes. I want to display only selected cubes (eg to show a slice of the data). It is efficient to render the cubes by creating a structured grid and then using glyph3D. But is there an easy way to turn individual glyphs on and off? I notice that vtkStructuredGrid has the ability to blank points, but blanking doesn't seem to affect the behaviour of vtkGlyph3D.

The position of the actors are changed in real time, but not all actors are updated at all times. Since rendering is heavy duty and I'm not able to even get 14 frames per sec. I am wondering if I can instruct the "renWin" which actors need to be updated and which need not be updated. I don't want to make an actor invisible, but I just don't want to update it. Is this possible? I suppose when I run "renWin->Render()", it updates all actors (even if their positions where not updated. I have another related question, Can I update the position of the actors in one thread and asynchronously run "renWin->Render();" in another thread? Are there some examples of multi threaded code?

Your script is not actually linking the example with _any_ libraries, so you should expect numerous undefined references. You could modify your script to link with the built VTK libraries, but it is far easier to run ccmake e.g. in VTK/Examples/GUI/Motif (where Example1.cxx lives) and have it generate a good Makefile. "make Example1" will then do the trick. I can't remember if this applies to the VTK4.0 release as well.

I'm using jre 1.3.1_02 on WinNT 4sp6 VC6 CVS build of > 8/26/2002. Do you have other versions of Java installed on your system? (check what you have in "C:\Program Files\Java" and "C:\Program Files\JavaSoft\JRE") I do have similar problem on WinXP with 1.3.1_04 and 1.3.0_02. However it works fine with 1.4.0_01. (all of them installed at the same time) I am do not know though what is causing the problem. Jarek __________________________________________________ Do You Yahoo!? Yahoo!

Message-ID: <3D6D36A3.6040408@xs4all.nl> I read a large unstructured grid ( ~10^3 -- 10^6 cells) which I visualise on the screen. I have enabled interaction with it by using an instance of vtkRenderWindowInteractor. So far all failrly standard. In "camera mode" (pressing "C"), the view on the grid changes instantaneous when I press/move the mouse. However, when I am in "actor mode" (pressing "A") it can take considerable time (a couple of seconds) when I have ~10^4 cells, and *much* more when the grid is larger. I can see that the CPU is very busy on the mouse click, apparently deciding which actor is to be moved. Once it has found the actor, I can almost painless move/rotate the grid. I have the feeling that too much work is being done here. I only wanted to rotate my grid. Can somebody help me out how to do this faster?

Maybe a tutorial can be found somewhere? = Anyway, compiling and (especially) linking the VTK stuff is not as simple = as it looks. In your case, you include the vtkCommon library first and = that's why you will get the link errors. Including the libs in the = following way will probably help: -lvtkIO -lvtkRendering -lvtkGraphics -IvtkImaging -lvtkjpeg -lvtkpng = -lvtkzlib -lvtkFiltering -lvtkCommon -lopengl32 BUT: It is probably the best idea to use CMake to generate the makefile = for you (see page 31 of VTK User's Guide). This approach is good, but gets = you into a bit of trouble if you want to use the GNU autoconf/libtool = approach as you will have to if you want to use FOX, for example.

I'm=20 attempting to use Microsoft's VJ# (java code)with vtk40 running under=20 XP.

I downloaded the dlls from = the vtk=20 website and did not rebuild them, nor did I rebuild the vtk.jar. =

If the DLLs are native Win32 Dlls being = accessed through JNI, then this is
not supported in Visual J#. You = will have=20 to move to using P/Invoke or COM
inter-op services of .NET = Fx.

If on=20 the other hand, these DLLs contain embedded .class/resource = files,
then you=20 need to convert the classes to managed assemblies before using in
VJ# = app.=20 For this you can use the VJ# binary converter tool (JbImp.exe).
When = using=20 JbImp.exe - please confirm that there are no legal restrictions

JbImp=20 does not support extracting embedded .class files in Win32 Dlls. = The

tool)=20 was run.
Regarding the behaviour of System.loadLibrary, we follow the = same=20 semantics

for in that path. If no path is specified then the search=20 heuristics of the

Your project files didn't work on my setup due to heap error with MSVC = (/Zm option) and they have been removed. Instead, I have added = CMakeLists.txt files to the appropriate locations. This setup is tested = and produces working projects which compile and run under Visual Studio = 7 dot NET. If anyone reading can test under MSVC 6 and confirm that it works, it = would be appreciated. TABS were converted to 2x. Apologies for resulting style errors. = Your headers/disclaimers were replaced with the standard vtk text. Many thanks for your demos. On a pesonal note - as an experienced vtk = user, but new to MSVC I'd like to see demos with buttons and sliders etc = that show how to design a complex gui that integrates with vtk. (eg = control the glyph sizes with a slider &etc) - No doubt this is not = really a vtk issue but rather one of familiarising oneself with the = development environment.

I have tracked down this memory address before and the problem seems to be in the vtkOpenGLPolyDataMapper.cxx class. I found the threads in the mail archives relating to this earlier and moved the vtk classes and destructors from the doc to the view but it didn't help. ... Detected memory leaks! Dumping objects -> {2216} normal block at 0x03787320, 5200 bytes long. Data: < Building> 00 00 00 00 00 00 00 00 42 75 69 6C 64 69 6E 67 Object dump complete. ... I must confess to having written some huge commercial apps using MFC, I'll add some complexity to these demos (sliders/buttons/splitters/doc archives) when I get a chance and send them to John.

ABI means Application Binary Interface defines, among other things, rules for name decoration. Kylix bc++ and gcc do not have compatible ABIs, which basically means that you cannot link a library produced by gcc with your Kylix programm and vice versa. Note that is is only true for C++, you can link C libraries with you Kylix programs. This is the reason why I tried recompiling VTK with bc++. You can also refer to the Borland newsgroups for further information on this isse (the Kylix documentation doesn't even mention it!). Also, I believe that is only true for the C++ compiler, the Delphi compiler does not have these problems. > Could you please elaborate? as a BCB6 user who's been working with vtk > for many years, I can't see why Kylix is going to > be ruled out. What > problems do you refer to Well, first it turned out to be rather difficult (IMO impossible) to configure the current version if cmake to produce correct makefiles for the Borland tools. Secondly, some source code changes were needed because of non-unix like behaviour of the compiler (although this might be useful for porting windows apps to linux). Thirdly, the compiled libraries still have some problem with memory allocation, which I could not figure out yet. I have spent two weeks now evaluating the use of Kylix in an upcoming project which also uses VTK and lots of other existing source code. From my point of view it is more feasable to use another platform for the GUI, which has proven to work well in combination with VTK (like QT). I do think Kylix is a very good RAD tool, but for what we want to do it seems that it just isn't ready yet. Maybe Kylix 4 will be ... However, if you try to get VTK to work with Kylix please stay in touch with me.

    $Cn  SetClipFunction $imp
    $Cn  GenerateClipScalarsOff
    $Cn  SetInsideOut 1
    $Cn  SetValue 0.5
$Cn Update
########## Now Cut The Full Structure to get better cut mesh ##############

vtkCutter $CE; #Generate cut lines
   $CE SetInput [$thresh GetOutput]
   $CE SetCutFunction $imp
  $CE GenerateCutScalarsOff
  $CE SetValue 0 0.5

######## Now Append cutter mesh  to front and back clipped Polys and map them ############

Set the height of the cylinder to be sqrt(x^2 + y ^2 + z^2) using vtkCylinderSource->SetHeight 3. Cross the vector (x,y,z) with the default axis of the cylinder (0,1,0) to get the axis to rotate about, which would be (z,0,-x) 4. Get the angle between the two vectors (using the cosine law where one vector is 0,1,0): sin(angle) = y / sqrt(x^2 + y^2 + z^2) 5. Create a vtkTransform object 6. Apply a translation to the vtkTransform using Translate() to (x0 + x/2,y0 + y/2,z0 + z/2) 7. Apply a rotation to the transform using RotateWXYZ with the angle from 4 and the vector from 3 8. Create a vtkTransformFilter and apply the vtkTransform from 5 to it. 9. Pass the vtkCylinderSource through the transform filter. I'm no geometry expert, that may not be the most efficient way to do things, but I think it will get the job done for you, unless I've made a stupid math error. If you look at the examples for vtkTransformFilter, I'll bet you find some code doing something similar to what you want to do. Kevin.

One question though: in your code I see / "SetScalarModeToUsePointData/ " etc. In my case, I have cell data. I have seen functions that convert cell data to point data (and vice versa), but from what I have seen these functions are useless in the sense that data is interpolated/averaged such that no sensible information is left. What I need is clipping a (unstructured) grid, but keeping the cell data alive. Does you code adress this problem?

Each display shows a different VTK actor. The first time the window is shown everything looks fine. but when I do a refresh of one of the windows, the actor is not displayed anymore and the other display turns black (background color) too. The strange thing is that when the two displays (vtkRenderWindow) have the same actor, everything is fine. I'm using VisualC++/Window2K with VTK4 Thanks for your help Julien From John Biddiscombe" I've been playing with wxWindows and want to evaluate it for vtk usage. = I've had a look at the wxVTKWindow class by D.Marshall & B.Todd. at=20 http://www.prism.gatech.edu/~gte552m/wxVTKWindow.html but it doesn't seem to be working under vtk4 and it's GPL'd which makes = it off limits to me anyway.

There is no need to create a special wxRenderWindow class, you should be able to call renWin->SetWindowId(wxWin->GetHandle()); to connect the windows. The only tricky thing is that the wxWindow has to be mapped to the screen before the first Render is called. - David -- David Gobbi, MSc dgobbi@imaging.robarts.ca Advanced Imaging Research Group Robarts Research Institute, University of Western Ontario On Fri, 30 Aug 2002, John Biddiscombe wrote: > I've been playing with wxWindows and want to evaluate it for vtk usage.

OK. I had planned on subclassing wxWindow and then doing = renWin->SetWindowId(this->GetHandle()); somewhere in the initialization. = I have so much legacy code for doing little things to the window (from = my Borland renderwindow classes) that I had hoped to create a whole = family of wxRenderWindows. One thing that may cause trouble is that I have options for turning = on/off stereo rendering (glasses etc) etc, but these require the window = to be destroyed and recreated. Is there a convenient hook into = DestroyHandle and CreateHandle under wx? > The only tricky thing is that the wxWindow has to be mapped > to the screen before the first Render is called. Noted. I'll remember this. I'm still only playing with wx right now, but = when I get there.... thanks JB From dgobbi@imaging.robarts.ca Fri Aug 30 19:02:05 2002 From: dgobbi@imaging.robarts.ca (David Gobbi) Date: Fri, 30 Aug 2002 14:02:05 -0400 (EDT) Subject: [vtkusers] wxWindows In-Reply-To: <000d01c2504d$5e4b6b20$0100a8c0@tigger> Message-ID: On Fri, 30 Aug 2002, John Biddiscombe wrote: > One thing that may cause trouble is that I have options for turning on/off stereo rendering (glasses etc) etc, but these require the window to be destroyed and recreated. Is there a convenient hook into DestroyHandle and CreateHandle under wx? A cheap trick is to just set the EyeAngle to zero when you want to turn off stereo. Otherwise, yes, you will have to destroy and recreate both the wxWindow and the vtkRenderWindow every time you switch. With some vendors' OpenGL drivers you can create a StereoCapableWindow and just use StereoRenderOn()/Off() to switch, but some other drivers will spew garbage if you do a non-stereo render inside a stereo context. > > The only tricky thing is that the wxWindow has to be mapped > > to the screen before the first Render is called. > > Noted. I'll remember this. I'm still only playing with wx right now, but when I get there.... There might also be some funky stuff you need to keep the wxWindow 'erase' from causing flicker, but this might just be for the GTK version of wxWindows. It should all be in the python script. - David From lisong@vrac.iastate.edu Fri Aug 30 20:43:58 2002 From: lisong@vrac.iastate.edu (Song Li) Date: Fri, 30 Aug 2002 14:43:58 -0500 Subject: [vtkusers] parallel library References: <3D6D4924.75676143@vrac.iastate.edu> <3D6DFDF3.6030300@cdnorthamerica.com> Message-ID: <3D6FCAFD.DF1FE765@vrac.iastate.edu> --------------8CE2E1D9AD8FE090B48FE2B5 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Thanks, Jeff.

[vtkusers] New feature: vtkImageDataToTkPhoto Message-ID: Hi all, I won't go into the rational behind this feature, rather I'll just expalain. I've added new Tcl and Python(Tk) commands into VTK. The command is called vtkImageDataToTkPhoto. Usage: vtkImageDataToTkPhoto image photo z image - in Tcl image is a vtkImageData, in Python it is the address string image.__this__[:-2] photo - the name of the photo widget returned from [image create photo] or Tkinter.PhotoImage() z - the z slice to take from the image data The command only handles 1,3, & 4 component unsigned char vtkImageData types. For python, I added a class called vtkTkPhotoImage as a wrapper class around this command. Since the Python code took a bit more "hack"ing, you can use vktTkPhotoImage wherever you need a Tkinter.PhotoImage. vtkTkPhotoImage has a new method PutImageData that takes a vtkImageData and a z slice, effectively hiding the call to vtkImageDataToTkPhoto.

I am trying to use VTK to visualise polynomials in real-time using measurement data (coefficients) obtained from an optical instrument. I am using VTK (MSVC++ 6.0) to visualise polynomials on a warped plane. Each time a measurement is made and a set of coefficients determined for the set of polynomials, I would like to update the window display to visualise the new data. I am still familiarising myself with actors, renderers, mappers etc. So far I just only managed to plot the polynomials themselves. In all examples it seems that rendering the window is the last operation performed in the code. Does anyone have any tips or example code for updating the window with a new dataset after it has been rendered? Any help would be much appreciated.

Message-ID: Hi Alex, I just can't resist a good movie... Is this a lighting effect? The branches seem to become increasingly shaded until they merge with the black background. Have you set up a positioned light source instead of the default 'headlight'? Would a white background clarify if black shading is making the branches disappear? The branch size effect may be due to resolution in the shading calculations. As you zoom out, a branch surface decreases towards being a just pixel or so wide 'on-screen', and its averaged surface normal may point further and further away from the camera. just guessing, Dave Pont "Alex Lear" To: "vtk users" Sent by: cc: vtkusers-admin@public.k Subject: [vtkusers] Actors disappearing on zoom - Video! itware.com 01/08/2002 11:20 Hello, I have about 1000 actors that make up a branch structure.

Add all terms, and put the sums in a symmetric 3 by 3 matrix (xx,xy,xz; xy,yy,yz; xz,yz,zz). This matrix represents an ellipsoid whose shape corresponds with the shape of your points. From this matrix you can calculate the eigenvalues and eigenvectors (see vtkMath). These eigenvectors and eigenvalues define the directions and lengths of the main axes of this ellipsoid. The vectors belonging to the largest eigenvalues give you the orientation of the requested plane. The position of the plane is determined by the centriod of your points.

For an example of how to calculate the major axis using the eigenvectors and values take a look at vtkOBBTree. The first level of the OBB tree is similar to what you are looking for. On my homepage www.imm.dtu.dk/~rrp/VTK there is a class (vtkPrincipalAxisTransform) that will transform a given shape to the principal axis of another shape. This class also contains the sought functionallity.

Yes, this is wierd.

Or is there any description in the net? The read me files I found in the distribution did not help a lot... When I tried to run a vtk example script, I got the error message tcl833.dll not found.

The patented code is not included in the binary distribution. To get that you have to recompile VTK yourself. Instructions for doing that can be found in the VTK books.

Digging in the code, I see: for ( ptId = this->Offset; (ptId < numPts) && (id < (this->MaximumNumberOfPoints-1)) && !abort; ptId += this->OnRatio ) The part that fails is "id < (this->MaximumNumberOfPoints-1)" since id is 0 and this->MaximumNumberOfPoints-1 is zero, it never falls in the loop. Changing it to a <= doesn't work for values > 1. I added a : if (this->MaximumNumberOfPoints == 1) { x = input->GetPoint(this->Offset); id = newPts->InsertNextPoint(x); outputPD->CopyData(pd,this->Offset,id); } else above it, but this may not be the best fix since there may be a way to handle the random case and the non-random case in the same way. If you need a test case, the Examples/VisualizationAlgorithms/Tcl/spikeF.tcl exhibits the problem if you add a ptMask SetMaximumNumberOfPoints 1 in there.

Message-ID: <91F8F22D85BFD411B13B000102B35995A1A5E9@mailsrv.int.profactor.at> Hi, I have a simple 2D Image (only black and white pixel) with a lot of noise. Are there some vtkFilters to reduce noise? How can i do this in C++ Thanks a lot From h.huisman@rad.umcn.nl Tue Aug 6 10:55:15 2002 From: h.huisman@rad.umcn.nl (h.huisman@rad.umcn.nl) Date: Tue, 6 Aug 2002 11:55:15 +0200 (CEST) Subject: [vtkusers] vtkImplicitBoolean bug Message-ID: Hi, Think I noticed a bug in vtkImplicitBoolean (IB). I use IB to combine AND transform several implicitfunctions. However, the transform doesn't seem to be working. Running debugger (ddd) I noticed that the ImplicitBoolean::EvaluateFunction(x) doesn't use the IB transformation. I would expect xt = IB->Transform(x) and then f = IF(xt) whereas it now directly calls f = IF(x) avoiding the transformation. Hope somebody can shine a light on this one.

Implicit boolean is a subclass of the = more general Implicit function which defines the transform and it just = got left out. See if you can add the necessary code to make it work and = then post it here. Probably you can just copy a chunk from one of the = other implicit classes...

There are plenty of examples in the Examples directory, just do a recursive text find for "vtkRenderWindow". -- charl p. botha http://cpbotha.net/ http://visualisation.tudelft.nl/ From YaelFeldman@aol.com Tue Aug 6 14:27:23 2002 From: YaelFeldman@aol.com (YaelFeldman@aol.com) Date: Tue, 06 Aug 2002 09:27:23 -0400 Subject: [vtkusers] colouring a surface according to one's own floatarray Message-ID: <5C6B353D.02F4561A.420A636E@aol.com> I am trying to colour a surface (a triangulated polygonal mesh) according to a floatarray listing numbers (that are calculated by the programme), one number corresponding to each of the polygon vertices.

There are various limits to the geometries that PAFEC can handle. For example, the angle between any two cell edges must lie within the range 15-165 degrees. There are also limitations related to the length of quadrilaterals with respect to their height. Does VTK offer any classes that can help me to process arbitrary meshes to meet these constraints? Is anyone else on this list doing anything similar? Thanks in advance for any suggestions.

Once you create your PolyData you can associate point scalars with the points of the data. Create a vtkFloatArray and then stick the scalars in it and then associate this array with your point data. Thats about all you need. pd = vtkPolyData() # this is your polydata object. You might generate it some other way. sc = vtkFloatArray() for i in range(pd.GetNumberOfPoints()): sc.InsertNextValue(_insert_your_scalar_here) pd.GetPointData().SetScalars(sc) cheers, prabhu From nundys@neuro.duke.edu Tue Aug 6 16:43:28 2002 From: nundys@neuro.duke.edu (Surajit Nundy) Date: Tue, 06 Aug 2002 11:43:28 -0400 Subject: [vtkusers] Accessing Arrays in Matlab-Java-vtk References: Message-ID: <3D4FEEA0.4050602@neuro.duke.edu> Is it possible to access a vtk array from matlab (such as vtkFloatArray or vtkUnsignedCharArray).
