Question 1:

are you making a off-axis frustum or a normal frustum?
we have fixed a bug in 2.0 that affected off-axis frustum.
if your frustum is a normal one, could you
send me a fragment of your code please?

thanks

jenny

Performers,

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?
