[vtkusers] Re: Stereo rendering

[Dr. Daniel James White PhD]

Hi Oeyvind,

you should use
SetSeteroTypeToCrystalEyes

but you will also need the correct stuff in your XFree86 config file to 
tell the left and right images to go to the correct scree/projector.
I'm not sure how to do thin, but someone will know.

Crystal eyes works on my red hat 8 box with VTK, using shutter glasses 
on a CRT display.
You may see a bug that only one of the images is displayed if you use 
an older VTK distro, but I believe it might be fixed in newest CVS.

People on the VMD mailing list might well know how to do the double 
projector trick, you could ask or look there.

cheers

Dan
