Hi Jorg,
Have you made stereo work? If yes please let me know how. I have similar
problem to what you had last Oct. I would very much appreciate it if
someone could give me a hint. Below is a brief description of my system
setting and what I did in attempt to achieve stereo effect.
=======
Setting
=======
Linux with nVidia Quadro graphics card (in Clone mode, stereo 4). The two
outputs of the graphics card are connected to two monitors (later will be
two polarized projectors)
==========
What I did
==========
Add
renWin StereoCapableWindowOn
renWin SetStereoTypeToCrystalEyes
right after
vtkRenderWindow renWin
in Examples/Tutorial/Step5/Tcl/Cone5.tcl.
Run it, hit key "3", then I got error message, saying "Adjusting stereo
mode on a window that does not support stereo type CrystalEyes is not
possible". As a result, I did't see any disparity between the left and
right renderings (they are identical). I suspect that the window failed to
configured itself to be stereo capable as I request.
Many thanks in advance.
