I'm having a difficulty that is not specifically from Performer, but I'm
certain somebody here could help me. I'm fairly new to Performer (worked
on it for about 6-8 months) so please forgive me if this is a stupid
question! I'm working with Performer 2.0.
I'm trying to setup a camera that can be off-axis; that is, the line
from the eyepoint doesn't pass through the center of the image and it is
not perpendicular to the image. My first idea was to create a frustum
with pfMakePerspChan and then to offset the axis it with
pfChanViewOffsets. However, this doesn't seem to work. Would there be a
way to describe the frustum directly with a pfMatrix? I guess I can do
it with GL calls but I have to be in the draw process, am I right?
Thanks
