[vtkusers] Problem with Crystal Eyes stereo and QVTKWidget

[Olivier Ameline]

Hello,

I have a polydata that I want to render in stereo inside a QVTK Widget.

For this I use the C++ code

renderWindow->StereoCapableWindowOn();
renderWindow->SetStereoTypeToCrystalEyes();
renderWindow->SetStereoRender(1);
renderWindow->StereoUpdate();

which does not work. There is no error message, but the polydata is not
displayed in stereo.


When I use 

renderWindow->SetStereoTypeToAnaglyph(); 

instead of 

renderWindow->SetStereoTypeToCrystalEyes();

the anaglyph type works.


I'm in Linux Fedora with VTK 6.3 and a Nvidia Quadro card. 
I can run successfully stereo examples (like glxgears -stereo).

Furthermore, the Crystal Eyes stereo works on my polydata when I use a
vtkRenderWindowInteractor, but I would prefer to use the QVTK Widget.


Do you know what's wrong with QVTK Widget and Crystal Eyes stereo in VTK 6.3
?

Thanks

Olivier.
