Hi,

    Do you guys know how to generate stereo pair
images correctly?
    What I am doing currently is to set offsets of two
cameras and rotate them a little bit.
    I read from a book that says the best way is to
use a method called Two Centers of Projection. How to
implement this method with Performer channel routines?
I also read about a message that says pfMakePerspFrust
should be applied.

    I used to read about a program(sfly.c) that
someone wrote as a stereo version of perfly. But I
couldn't find it on sgi.com ftp site.

The book talking about the two centers of projection
is:
Stereo Computer Graphics and Other True 3D
Technologies

Thanks a lot!
