Question 1:
I have an app that is based on perfly. I modified the frustum via
pfMakePerspFrust() and everything is fine. However, when moving the near
clipping plane via the gui (pfChanNearFar()), I find that the vertical FOV
changes. This was verified by printing the results of pfGetFrustFOV() before
and after pfChanNearFar(). Note that changing the far clipping plane seems
to work correctly. What am I doing wrong?
Question 2:
I'm trying to model an out-the-window scene for an aircraft flying at high
altitude (40,000 ft) on a relatively clear day. Because I must be able to
see things far away (the horizon) and things close (my wing man), my near
clipping plane is small, and my far clipping plane is large. It seems that
I'm out of luck trying to get Performer's fog model to give me a little haze
near the horizon. (It works if the near clipping plane is relatively large).
Is there a way to do this?
For the record: Performer 1.2, Crimson RE, Irix 5.3.
Thanks,
Shawn
