Are you making sure that the render window you create is capable of
producing stereo images?  If I'm not mistaken, you have to call
vtkRenderWindow::StereoCapableWindowOn() (see VTK online documentation
for details) *before* any rendering is done.  Otherwise VTK complains if
you try to activate stereo rendering, because by default it does not
create a stereo-capable window.  I hope this helps!

Kind regards,
