[vtkusers] Stereo rendering

[Øyvind Knudsen]

I solved it. The problem was qt! I'm using vtk inside an application written in python with qt as the GUI library. I used the QVTKRenderWindowInteractor from <http://gerard.vermeulen.free.fr/> to incorporate the vtk renderer into the qt GUI. Evidently, the QWidget class does not support stereo rendering and since QVTKRenderWindowInteractor inherits QWidget, the renderer was not capable of stereo renderering. I made the QVTKRenderWindowInteractor inherit the QGLWidget from the pygl module instead, and voilá: Stereo rendering!

I got another problem though: After closing a stereo capable vtk window, one of the projectors freezes the image, while the other projector keeps working as usual. This makes the display cluttered, as one eye looks at a frozen image, while the other lookas at the operating system desktop as usual. 

Any ideas how to solve this?
