Hello all,
  Can someone send me an example of how to render a scene with an ortho
projection matrix? I assume one uses a pfFrustrum, but I don't understand
where it would get attached in the hierarchy? The code I am working with
was written under Performer Rev 1.0, and I don't see anything having to
do with perspective projections in there either (other than near/far clip
planes). So I'm really sure where to start.
  As I am not a regular reader of this group, please send responses to
myers++at++ncar.ucar.edu

Thanks,
Bill Myers
