Hi there,

Has anyone had any experience of using a uniform scale in the view matrix
of a pfChannel?

I've been playing around with this and it appears to have some strange and
unexpected effects on the near clip plane. I've been using pfChanViewMat to
set the pfChannel matrix.

If I use a scale of < 1, then objects appear to clip sooner than I would
have expected. If I use a scale of > 1, then objects don't appear to clip
as soon as I would expect, in fact sometimes the objects are culled out
before they are clipped.

I'm using Performer 2.0.2 and IRIX 6.2 on an Indigo 2 Max Impact.

I'd be grateful for any ideas or suggestions.

Thanks.
