Hello,

How to set several scalars to vtkPoint ?

Seems vtkDataPoint scratchs the previous scalar array ?!

vtkSmartPointer<vtkIntArray> data1 = 
vtkSmartPointer<vtkIntArray>::New(); data1->SetName("data1");
vtkSmartPointer<vtkIntArray> data2 = 
vtkSmartPointer<vtkIntArray>::New(); data2->SetName("data2");
for (...) {data1->SetValue(idx, d1[i]); data2->SetValue(idx, d2[idx]) }
uGrid->GetPointdata()->SetScalars(data1); // OK
uGrid->GetPointdata()->SetScalars(data2); // data2 scratch data1 ?!

uGrid->GetPointdata()->SetActiveScalar("data1") does not do what I need 
: seems that it activate data1 back but "scratch" data2 back.

uGrid is a vtkUnstructuredGrid : the final goal is to write the grid to 
a file (with vtkWriter). In this file, I'd like to have BOTH data1 and 
data2 for points.
I only get either one or the other... How to get both ?

Also tried to create a N-sized-vector (N=2 or 4) to associate to the 
vtkPoint : does not work as it seems vector dimension MUST be 3. I 
somebody knows a solution to attach a N-sized-vector to a vtkPoint, it 
could solve my problem

Try
uGrid->GetPointdata()->AddArray(data2);

KO ! Does not work (realize I tried this before !) => I only get data1 
OR data2 (never both of them) in the written .vtu file...
It is possible to make this work or to create a N-sized-vector.

BTW, data1 is "pressure", data2 is "velocity" (that is data 1 and 2 are 
not related to each other)

May use a lookup table ? Not familiar with that but seems it's not what 
I need ?!...

Houssen,

PointData (as CellData) is basically a set of arrays where some of them can
be flagged as "the normal array", "the texture coordinates array", or even
"the default scalar array".
Only one of the arrays of the PointData can be tagged a the scalar array
but it does not mean you cannot have more than one array that could be
considered as a scalar array.
Those flags are used by some VTK filters/algorithms to determine on which
array to operate by default there are other mechanism (ie.
SetArrayToProcess) to specify the
array(s) to be used by a filter. See vtkDataSetAttributes
<http://www.vtk.org/doc/nightly/html/classvtkDataSetAttributes.html>for
more info on this mechanism.

As Bill said, try this:

  vtkSmartPointer<vtkIntArray> data1 = vtkSmartPointer<vtkIntArray>::New();
data1->SetName("data1");
  vtkSmartPointer<vtkIntArray> data2 = vtkSmartPointer<vtkIntArray>::New();
data2->SetName("data2");
  for (...) {data1->SetValue(idx, d1[i]); data2->SetValue(idx, d2[idx]) }
  uGrid->GetPointdata()->AddArray(data1);
  uGrid->GetPointdata()->AddArray(data2);
  uGrid->GetPointdata()->SetScalars(data1); // specify that data1 is the
array flagged as the scalar array

Save your grid and you will have both arrays saved but only "data1" in the
vtk file output for sure.

Sorry last sentence is was incomplete:

Save your grid and you will have both arrays saved in the vtk file output
for sure - and you will see that data1 is tagged as the SCALAR array.

Message-ID: <CADZJ4hMF+y1u6o6R0ddmoano=DtQF06oC+bZfWKjvjC_LZBQqw@mail.gmail.com>

Folks,

The new remote module is SplineDrivenImageSlicer based on the VTK
Journal article:
http://www.vtkjournal.org/browse/publication/838 by Jerome Velut.

I forked the git repo from the VTK Journal, reorganized the tree and
converted the code to vtk7.

Tests were included by the author.

I also made a wiki example of the vtkFrenetSerretFrame class:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Remote/FrenetSerretFrame

I will also add an example to show illustrates the spline driven sampler.

The example page tells how to build the new remote module.

Enjoy,

Bill

Subject: [vtk-developers] OffScreenRendering crash on CircleCI (Mac OSX)
Message-ID: <CAEcL5t5rXG7gv0HA3-ynOg_tHc1bxM-NOWd74kGR26GMcBFN3w@mail.gmail.com>

Folks,

We?re running into a strange crash on mac containers (OSX 10.11.6) created
by CircleCI with VTK (OpenGL backend).

VTK compiles fine and seems to work with OffScreenRenderingOff but crashes
at the first OpenGL call with OffScreenRenderingOn(). Unfortunately, I
can?t reproduce this on my mac machine and haven?t been able to make
headway within the half hour that CircleCI provides.

Again, this is the OpenGL backend. No crashes with the OpenGL2 backend.
If anyone has come across this or has an idea how to debug/reproduce/fix
this, kindly drop me a hint.

Thanks,
Sankhesh

Message-ID: <SN2PR05MB2653FE64A54A81AECD95F0F0EC0D0@SN2PR05MB2653.namprd05.prod.outlook.com>

Hello,



I am having problem running the VTKRenderingOculusCxxTests program. I get the following error -- see the attached picture.

I am using Visual Studio 2013 and the latest Oculus SDK 1.130.



To be sure, I did the following

1.      Recompiled the Oculus SDK libraries on VS 2013.

2.      Cleaned and rebuilt the VTK libraries



Standalone program with Oculus SDK works fine on the commercial version of Oculus Rift. I am having this problem only with VTK.  I might be doing something wrong when building the library.



Any help is greatly appreciated.

Have you tried using 'depends' (http://www.dependencywalker.com/) on that
DLL? It may be able to give you an idea of what is wrong, or if there is
some dependent lib/dll which is causing the problem instead.

Subject: [vtk-developers] Issue calling GetRange() on
	vtkColorTransferFunction from Python
Message-ID: <CAPiw4fCBA81+uHaRxASUuRCjpn73PPvrcv9ueJ5XQg=PJsT4dQ@mail.gmail.com>

Hi folks,

I recently noticed this seems broken in VTK master, while it was fine in an
older VTK (around December 2016).  Here is how I reproduced the issue:

(in a vtkpython session)

from vtkRenderingCorePython import vtkColorTransferFunction
f = vtkColorTransferFunction()
f.GetRange()

While this used to return (0.0, 0.0), it now returns something
like: '_0000000000ad0880_p_void'

Does this ring any bells for anyone?  David, are you aware of some change
in the Python wrapping that may have caused this change in behavior?

Cheers,
Scott

Sankhesh,

You don't give enough information for anyone to help you.  If you can't reproduce, what can any of us say if we don't even have your code?  :)  How about at least a backtrace of the crash, that might be something someone recognises.

Cheers,

Even though I authored those MRs, it seems to me too late to merge them since the 8.0 branch is imminent.  Maybe after 8.0 is branched, they could be merged to master?  Will an eventual 8.0.1 or 8.1 come from master or the 8.0 branch?  It is indeed not clear when such breaking changes can actually get merged...

It looks pretty good to me.

I'm a little trepidacious about 'auto'.  I think it can certainly be beneficial if used judiciously, but I worry that overuse will hurt the readability and debuggability of the codebase.

A shame that VS didn't support constexpr until recently, it would be nice to use too.

In general, one thing I've always liked about VTK's C++ is that it isn't unnecessarily 'clever' using any and every funky C++ feature.  I hope that continues.

Cheers,

Hi Sean,

I understand. The issue is cataloged here:
https://github.com/UV-CDAT/vcs/issues/130

The issue only occurs on a CircleCI provisioned container and I was unable
to reproduce it on a physical machine. By asking this question here, I
wanted to see if anyone else has come across and tackled this issue.

Since my previous email, I was able to test a sample OpenGL application and
reproduce the crash on a CircleCI VM, indicating it is an opengl/driver
issue specific to circleci machines.

Thanks,
Sankhesh

The doodle poll indicates that Thursday April 27th is a good date.

Hope to see many of you then.

Apologies for not saying so earlier but I'm going to delay 8.0 to give
people time to make the changes mentioned in this thread and because the
project that requested it slackened. I'm now aiming for a May 1st branch.

8.0.1 will come from the 8.0.0 tag (at that point aka release branch) and
only if important bugs turn up in 8.0.0.

8.1 will come from master a few months down the road.

Subject: [vtk-developers] Java wrapping
Message-ID: <CAL9W3unur3QsE=afPZQtBLQGF4A3hyCvLEARZjgEvxGkXbRGZQ@mail.gmail.com>

Dear VTK Developers!

I am a BsC student and now I'm writing my degree thesis. I programming in
Java and I would use the vtk for the visualize my 3D model. I use MacOS
10.12.2 (Sierra).
I downloaded from the web the latest version of VTK and I followed the
instruction of vtk wiki. I configured the building with CMake and I used
make command to compiling. After that I installed the vtk with make install
command. In the terminal appeared the /usr/local/lib folder with the
vtk.jar and .dylib files.
At the CMake step I signed over the default ON variables the VTK_WRAP_JAVA,
VTK_JAVA_INSTALL, VTK_JAVA_CLEANUP_INSTALL fields. I added the following
variables to CMake correspond to VTK wiki and signed ON: DVTK_USE_QVTK,
DVTK_USE_CARBON, DVTK_USE_GUISUPPORT and DCMAKE_INSTALL_PREFIX=/usr/local.

I use NetBeans development environment and I setted up the vtk.jar to the
Libraries and I added the following Virtual Machine options:
-Djava.library.path="/usr/local/natives-Darwin-x86_64"

When I would run a a simple code thrown the following exception:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no vtkCommonJava
in java.library.path

The source code contain this:
 static {
    System.loadLibrary("vtkCommonJava");
    System.loadLibrary("vtkFilteringJava");
    System.loadLibrary("vtkIOJava");
    System.loadLibrary("vtkImagingJava");
    System.loadLibrary("vtkGraphicsJava");
    System.loadLibrary("vtkRenderingJava");
  }

I have no idea what is the solution for this problem.

Thank you for taking the time to read my letter.

Hi Csaba,

I'm hoping that /usr/local was empty as the VTK_JAVA_CLEANUP_INSTALL
property will wipe that directory before packaging the jars and so on.
Usually, when using VTK_JAVA_CLEANUP_INSTALL a local dedicated directory is
set to CMAKE_INSTALL_PREFIX. Then you can copy its content anywhere else.

Regarding your issue I believe that you have all library names. Instead you
should be using the helper enum vtkNativeLibrary. Which can be used like in
our Demo example here:
https://github.com/Kitware/VTK/blob/master/Wrapping/Java/vtk/sample/Demo.java#L51-L61

Hi all,

What TBB versions are supported by 7.1.1? Is the one in Ubuntu 16.05
(2015.09.R2-1) sufficient?

Thanks in advance,
Elvis

Hi Elvis,

We are only using basic TBB features (parallel_for, atomic and
enumerable_thread_specific) so it should work with that version. Please let
us know if it doesn't work for you.

Thanks

Alright, thanks for the info. I'll have a go at it.

The reason I asked is that I just found out that my build on Ubuntu
was neither using TBB nor OpenMP, so I think the vtkSMPTools I have
will do everything sequentially, so I wanted to fix that :)

Hi Elvis,

In prior emails you mentioned that you use a QVTKWidget subclass (or
QVTKWidget2?) that contains a workaround for this event issue.  Is this
class something that you can share?  Do you recommend using this
workaround, or is the patched qt5.5 preferable?

Sure, I'm attaching VTKWidget.h/cpp, which contains the QVTKWidget
subclass I'm currently using.

If I remember correctly, it was David Gobbi who led me to this
workaround, so he should have the credit.

It's of course preferable to use a fixed Qt (5.6 or higher, or patched
5.5.1), but I'll use this workaround until the patched package is in
the xenial-updates repo (the upload to xenial-proposed seems to take
some time, I guess the approvers are busy).

My strong preference is only call Render() within Qt's paintEvent(),
and to disable Render() everywhere else.  Then, when I want VTK
to render, I call update() on my QWidget to let Qt know that it has
to re-paint.

This keeps things nicely synchronized between VTK and Qt, which
is especially important for things like resizing the window.

Another thing that I do differently from QVTKWidget is that I install
a dummy QPaintEngine so that Qt never executes any drawing
commands within the widget, but that's a separate issue from the
event loop bug.

Thanks David & Clint for your insights.

David: Is your VTK/Qt widget class something you could share? It
sounds like it has accumulated a lot of battlefield wisdom that could
be useful to others :)

Regarding your noop QPaintEngine, what problem have you bumped into
that this is solving?

Subject: [vtk-developers] Using system fonts on Windows (fontconfig
	equivalent?)
Message-ID: <CAE-7VJ=A3YUvMeDeYHQsiKvetEdh_PNYX5zKip3qv6LfAha7tg@mail.gmail.com>

Hi all,

Cross-posting since I'm not sure if vtkusers@ or vtk-developers@ is
most appropriate for this.

On Linux, I'm using the vtkRendereringFreeTypeFontConfig module, so
that I can use system fonts (e.g. for charts labels et.c). The goal is
to make VTK fonts match those used by Qt, so I'm using
QFontDatabase::system(...) to query for the user's preferred font, and
then use that in my VTK code. This is all working quite well.

I'm now porting the application to Windows. Does VTK have any support
for loading system fonts on Windows? Something similar to the
vtkRendereringFreeTypeFontConfig, but for whatever font backend
Windows uses?

If not, has anyone had luck in building fontconfig for Windows, and
using the vtkRendereringFreeTypeFontConfig module there? (I'm not even
sure if fontconfig has support for hooking into Windows' font backend,
so this may not be a solution at all).

Many thanks in advance,
Elvis

The issue (I believe) is that you are not using the EDT to do your
interaction with VTK.

Specially for the part below:

    //
    // now we loop over 360 degreeees and render the cone each time
    //
    int i;
    for (i = 0; i < 360; ++i)
      {
      // render the image
      renWin.Render();
      // rotate the active camera by one degree
      ren1.GetActiveCamera().Azimuth( 1 );
      }
    }

Moreover, on Mac, you can not really use the standard render window with
Java. You should build VTK with JOGL and use the JOGL rendering component
like in the example here:
https://github.com/Kitware/VTK/blob/master/Wrapping/Java/vtk/sample/rendering/JoglConeRendering.java

For JOGL, you may want to read that first:
https://github.com/Kitware/VTK/blob/master/Wrapping/Java/README.txt

It's part of an internal project, so I can't release it (or at least, not
yet).

Regarding your noop QPaintEngine, what problem have you bumped into
> that this is solving?


This was needed in order to get rendering to work on a Windows system.
Qt was always erasing the VTK scene by painting over it with the widget's
background color.  I tried setting the WA_NoSystemBackground flag and
the WA_PaintOnScreen flag to stop Qt from doing this, but the only trick
that always worked was replacing the QPaintEngine with a dummy.

AFAIK, the only option on windows would be to load the font file
directly using vtkTextProperty::SetFontFamily(VTK_FONT_FILE) and
vtkTextProperty::SetFontFile(...). I've never heard of FontConfig
being used on Windows, but I haven't really looked into it, either.

Good luck!

Ah, very interesting. I was porting our app to Windows just today actually.
Only just gotten it to build, but can't test running it yet since I'm
relegated to VirtualBox until we get a Windows test machine, and the
VirtualBox OpenGL driver is not capable enough (ARB_geometry_shader4
missing, probably more). Thanks for the heads up, I may run into this soon.

Hm, alright.

QFont (as returned by QFontDatabase::system(...) etc.) unfortunately
can't give me a specific font file (it's not part of its API, QFont
should actually be thought of as query to the underlying font backend,
not a specific font file), so I don't have a file path to pass to
SetFontFile :/

Would it make sense as future improvement to add a VTK module similar
to vtkRenderingFreeTypeFontConfig, but which interfaces with the
Windows font backend?

How are people dealing with this in VTK applications today? Do they
just accept that fonts in VTK will look out of place compared to
surrounding UI elements and other programs (and not respecting the
user's font settings)? What's the situation on macOS? We're planning a
port to macOS as well, and would of course like to respect the user's
font choice there as well.

Sure, that would be useful.

Most of the applications I'm aware of that use a consistent font
across components with VTK do so by specifying a font file explicitly
as part of their distribution, or just settle for matching
serif/sans-serif/monospace properties.

Alright, I guess that's what we'll do for Windows/macOS for now then,
even if the goal was to obey the user's settings and not impose a
specific shipped font. The problem is that the font we choose to ship
may not fit in well with the user's chosen font (which the surrounding
Qt GUI will respect).

This is the same underlying issue as:
https://bugs.llvm.org//show_bug.cgi?id=18218

libc++ interpreted the standard in a way that doesn't make sense, such that
any isinf and isnan arguments are cast to double (this makes no sense
because the Inf bit pattern is a perfectly valid integer much smaller than
the typemax).

Whereas libstdc++ only defines std::isinf for float/double/long double, and
all other types are a constexpr false.

Message-ID: <d35d660e45ee5b35bfdbe033fd95f781@imap.ipgp.fr>

How to "see" labels (= "names") of points of a vtkUnstructuredGrid in a 
VTK window ?

Is there an existing filter for that ? (looked for it but didn't find 
it)
Should I use vtkLabeledDataMapper: if yes, how ?
Must I write myself a dedicated filter for that ?

I have a valid vtkUnstructuredGrid (named "grid" in the following code 
snippets - points and cells have been set without problems).

Now I add a string array to points (from a list called iVertexNames):
vtkSmartPointer<vtkStringArray> ptNames = 
vtkSmartPointer<vtkStringArray>::New();
ptNames->SetName("names");
for (unsigned int idx = 0; idx < iVertexNames.size(); idx++) 
ptNames->SetValue(idx, iVertexNames[idx]);
grid->GetPointData()->AddArray(ptNames);

I have a VTK window in which I render the grid (works OK): now, I want 
to add point labels to the scene (does not work).

I tried several things that didn't work:
1. grid->GetPointData()->SetActiveScalars("names")
    => nothing change in the VTK window.
2. Add an (2D) actor whose mapper is a vtkLabeledDataMapper (+ calling 
SetLabelModeToLabelScalars)
    vtkSmartPointer<vtkLabeledDataMapper> lblMap = 
vtkSmartPointer<vtkLabeledDataMapper>::New();
    lblMap->SetInputData(grid->????()); // Does NOT compile ? What to 
put here ?
    lblMap->SetInputData(grid->GetPointData()->????()); // Does NOT 
compile ? What to put here ?
    => Does not compile (need to use SetInputConnection ? With which 
argument ?)
3. Use an existing filter for that : didn't find it ! 
(vtkVertexGlyphFilter seems to support only int/double/float ?)
    => Does not exist

Is there another way to do that ?

Message-ID: <fcd10f967c45cb41c76d254b075b26fe@imap.ipgp.fr>

With VTK >= 6, how to "choose" between SetInputData() or 
SetInputConnection() ? How to know which one SHOULD be used ?

I read carefully this 
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Replacement_of_SetInput, 
and, I digged several VTK examples 
http://www.vtk.org/Wiki/VTK/Examples/Cxx... Lot of things clarified but 
I'am still confused in exercising this: I feel like I missed some major 
stuffs...

To make it quick, my understanding is that :
1. If I need B to be modified if A is changed, I NEED to do 
"B->SetInputConnection(A->GetOutputPort())".
2. Otherwise, "B->SetInputData(A)" is enough (A will be an input of B 
BUT no link will be set between A and B : changing A does not trigger 
update of B).

Up to here I guess (?) I'am right (at least for the big headlines)... 
Stop me here if not !

Now, I want to have a source (grid) and I need to apply a filter on it. 
Say that in a call back I modify the source: I want BOTH source and 
filter to be updated when call backs are modifying the source. Here is 
what I have:
vtkSmartPointer<vtkUnstructuredGrid> spGrid = 
vtkSmartPointer<vtkUnstructuredGrid>::New(); // Source
// Fill the source with points and cells...
vtkSmartPointer<vtkVertexGlyphFilter> spVertexGlyphs = 
vtkSmartPointer<vtkVertexGlyphFilter>::New();
spVertexGlyphs->SetInputData(spGrid); // Case 2
vtkSmartPointer<vtkPolyDataMapper> spVertexGlyphMap = 
vtkSmartPointer<vtkPolyDataMapper>::New();
spVertexGlyphMap->SetInputConnection(spVertexGlyphs->GetOutputPort()); 
// Case 1 : the filter is updated if the source is modified.

This seems to works: the filter is updated if the source is modified.

But, this does NOT work: the source is NOT modified (= updated in the 
VTK window) when the callback modify it (so the filter may OR NOT be 
updated accordingly ?!).

I expected to be compelled to do:
vtkSmartPointer<vtkDataSetMapper> spGridMap = 
vtkSmartPointer<vtkDataSetMapper>::New();
spGridMap->SetInputConnection(spGrid->GetOutputPort()); // Compilation 
KO because there is not SetInputConnection or GetOutputPort ???
So I'am compelled to do (found lots of examples that do that):
spGridMap->SetInputData(spGrid);
... And I end up with a grid that does NOT update in the VTK window 
when call back modify the source.
I found a way to update it: the callback modify the grid and, at the 
end of the callback, I added "spGrid->Modified()", this triggers the 
update of the source.

So basically, I did what I need ... But:
1. Is the "spGrid->Modified()" a hack ? Or is it the "right" way to do 
? If yes, why (as it seems to bypass the update process) ?
2. Why is there no SetInputConnection on spGridMap ? Why is there no 
GetOutputPort on vtkUnstructuredGrid ?

I just would like to understand the logic behind....

Hello guy,

Anybody knows which Module in CMake I have to check to build my version of
VTK 7.0 with the following classes:

#include <vtkPCANormalEstimation.h>
#include <vtkSignedDistance.h>
#include <vtkExtractSurface.h>

Thank you very much for any help.

Hi Joao,

A quick answer is:
#include <vtkPCANormalEstimation.h> - > vtkFiltersPoints
#include <vtkSignedDistance.h>            - > vtkFiltersPoints
#include <vtkExtractSurface.h>              - > vtkFiltersPoints

In the future, if you want to search for the right module for a specific
class, you can do things as following:


   - find the path to the file:

                  Ex. $VtkSrc/Filters/Points/vtkSignedDistance.h

   - look for a file in this path called module.cmake.  the name after
   *vtk_module(* is the module you are looking for.

Hope it helps.

Hi Liu,

Unfortunately, didn't help. I am not looking for that. Actually my question
is about CMAKE building VTK 7.0 with support to the following:

#include <vtkPCANormalEstimation.h> - > vtkFiltersPoints
#include <vtkSignedDistance.h>            - > vtkFiltersPoints
#include <vtkExtractSurface.h>              - > vtkFiltersPoints

But, I just figure out that VTK 7.0 doesn't have support to
vtkFilterPoints. The CMAKE Module should be something like Module_SRCS.
This is what I am trying to find.

I am hopefully that somebody can help!!

Thank you

Elvis,

I finally recently updated our app to use the macOS system font.  I really feel it should be VTK's default behaviour, because otherwise most non-English characters are not going to render, and in this day and age, Unicode should "just work".

I guess such a change would complicate VTK's test suite, at least the tests that compare images, because the system font is often tweaked from OS release to release.

Perhaps VTK should at the very least provide an API that does the platform-specific work to return the path to the system font (for a given string at a given size).

Here's our Mac code if you want to copy it:

	vtkTextProperty* property = textActor->GetTextProperty();
	const char* fontPath = [[self fontPathForString:inString size:14] fileSystemRepresentation];
	property->SetFontFile(fontPath);

and

- (nullable NSURL*)fontPathForString:(nullable NSString*)inString
                                size:(CGFloat)inSize
{
	NSURL* fontUrl = nil;
	
	if (inString)
	{
		NSFont* startFont = [NSFont systemFontOfSize:inSize];
		CTFontRef font = CTFontCreateForString((__bridge CTFontRef)startFont,
											   (__bridge CFStringRef)inString,
											   CFRangeMake(0, [inString length]));
		if (font)
		{
			NSFontDescriptor* fontDesc = [(__bridge NSFont*)font fontDescriptor];
			fontUrl = [fontDesc objectForKey:(__bridge NSString*)kCTFontURLAttribute];
			
			CFRelease(font);
		}
	}
	
	return fontUrl;
}

Thanks a lot for this snippet Sean, it'll come handy when I turn my
attention to macOS.

A cross-platform helper like you mention would sure be a useful addition.

Subject: [vtk-developers] issue with interactor in viewport
Message-ID: <add4e879e49985e54cfbf4b4a6bd327a@sonic.net>

I currently have two viewports (a left and right viewport) but the
interactorstlye for the right viewport isn't working correctly. It
should display the labels of the different slices of the pie chart on
hover, but the hovering only works in the left viewport. It looks like
the "position" of the interactor is off. I attached a screenshot of this
issue (this is when my mouse is hovering over the left viewport). 

# Set up a 2D scene, add a chart to it 

view = vtk.vtkContextView() 

chart = vtk.vtkChartPie() 

# Add renderer to render window and set viewport 

renWin.AddRenderer(view.GetRenderer()) 

view.GetScene().AddItem(chart) 

view.GetRenderer().SetViewport(viewport2[0], viewport2[1], viewport2[2],
viewport2[3]) 

# Allow interactive piechart 

style = vtk.vtkContextInteractorStyle() 

style.SetScene(view.GetScene()) 

renWinInter.SetInteractorStyle(style)

Hello,

Just a quick reminder about the upcoming VTK hackathon.

The focus area will be VTK examples. Two different sets of which can be
found
here:
https://gitlab.kitware.com/vtk/vtk/tree/master/Examples
and here:
http://www.vtk.org/Wiki/VTK/Examples

We'll start at 9:30 EST time. If you happen to be near Clifton Park, NY,
USA, drop me a line asap and I'll get you in to the building.

Otherwise you can meet up with everyone online here:

Dave,

For those attending the hackathon I suggest they fork the VTK wiki
examples repo at https://github.com/lorensen/VTKWikiExamples and build
them.

Also, I'd like to give a short talk at the beginning of the hackathon
to describe the current wiki example background and mechanisms.

Thanks,

Bill

Hi guys,

has any progress been made regarding this bug so far 
(https://gitlab.kitware.com/vtk/vtk/issues/16797)? It seems nobody is 
responsible for this bug any more. In the old mantis bug tracker Marcus 
was assigned to solve the bug. So far I remember two weeks afterwards 
reporting the bug all tickets were moved to new bug tracking system. The 
assignee field was left empty during this process.

Best,

Hagen

I ran into this just now.  I looked deep enough to see a cppCheck
(15f924ddd5ff6e72abfaa1ab2a8da9c9866dc686) topic that was merged in the
last few days, and I was just making a comment on that closed MR.

I installed updates on it yesterday morning and rebooted it.  And it looks
like that is about the time the errors started... I'll look into it.

Apparently I forgot to reboot after the updates or it was canceled.  So I
rebooted the machine now just in case that had anything to do with it.  I
don't see anything weird on there.

Scott tracked it down, recently merged topic. I made a fix we can see if it
solves it.

Hi,

A thought on these tests -- I'd like to add minimal testing to some of
them. The thought here being that we both show good coding practice as well
as verify that the examples work as expected. The concern though is that
this could make the examples too long and obfuscate what we're trying to
demonstrate in an example.

Below is what I was thinking for the XMLPUnstructuredGridWriter example (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/XMLPUnstructuredGridWriter). It
roughly doubles the amount of lines in the example file.

Thoughts on this? At the VTK hackathon it seems to generally be thought of
as a good idea but I thought I'd put it out to the full dev list.

Thanks,
Andy

Hi,
although the example in this case does not seem too long to me, reaching a
consensus in terms of what results in a too long code or an overly
complicated example may be hard.

There is already some sort of regression/baseline testing if the test
produces an output in terms of an image/file, right?

Without harm to the idea of steadily adding more tests to/improving the
existing ones, if the examples are the entry-point for newcomers, I
wouldn't add explicit regression in their code.

I'd favor the idea of making clear in the examples what is essential for a
VTK class to be used. Otherwise, if a given class requires a couple or a
few examples to show all of its potential or essential features, I'd add
them as needed.

I just wanted to say that I was very excited to see this event! It seems
like it's going well already - high five to all involved!

Subject: [vtk-developers] Transitioning WikiExamples to gitlab
Message-ID: <CADZJ4hPOjM3jA0w-ofqsz61R3-RcNX4NCXLbNELQ9w0YuC0K=g@mail.gmail.com>

Folks,

At Thursday's hack-a-thon we discussed moving the VTK Wiki Examples to
a gitlab wiki. The main advantage is that the gitlab repo would
contain the master copy of the example. Currently the wiki contains
the master copy.

I am experimenting with gitlab's wiki to see what it would take to
transition to gitlab's wiki. There is good news and bad news.

First, look at this page that I created manually:
https://gitlab.kitware.com/lorensen/VTKExamples/wikis/Cxx/Points/DensifyPoints
and compare to the media wiki page:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/DensifyPoints

Good news is that is looks pretty good and the image can be inserted
from the gitlab repo.

Bad news #1: you cannot include a file in a markdown page.
Bad news #2: the name displayed for the markdown page Densifypoints is
not the same as the tree name nor the markdown file name.
Densifypoints versus DensifyPoints.

Bad news #1 can be resolved by programmatically  creating the .md file
in the gitlab wiki. We could create scripts SyncWikiToRepo and
ScrapeRepo. These scripts are similar in intent to what we do now with
the media wiki's SyncRepoToWiki and ScrapeWiki.

Bad news #2 is more troublesome and I don't have a solution. I don't
know why gitlab is converting my camelcase names.

I have made some progress. The C++ examples are populated. See:

https://gitlab.kitware.com/lorensen/VTKExamples/wikis/Cxx

I can't get rid of the file listing on the left.

The wiki pages were created automaically from the pages in the repo.
Still very crufty but we should be able to see if this will work for
us.
