[vtkusers] stereo rendering

[Steffen Oeltze]

Dear VTK-experts,

I'm programming a volume rendering application that does stereo 
rendering on a Dresden3D-
display. I'm using a VolumePro500 board to speed up the rendering 
process. Unfortunately,
this board only supports parallel projection. However, my stereo pairs 
are calculated using
perspective projection.
I know that VTK has already implemented a support for this display and 
it works fine for
both types of projection but when I started to think about the 
mathematics behind this
process I got confused. How are the stereo pairs computed in parallel mode ?

I'd be grateful for any thoughts on that,
Steffen Oeltze
