In Performer, is it possible to get the viewing frustum in the form
of a matrix?

i.e. in GL, "perspective" takes the fov, near & far specifications and
loads the resulting matrix on the stack.

Similarly, in performer, after specifying the viewing frustum, by using
pfChanNearFar(..)
pfChanFOV(..)
pfMakePerspFrust(..)
is there a way of directly getting the resulting frustum in the form of
a matrix (need not necessarily replace TOS as perspective does)?

Also, what is the structure of pfFrustum?

Thanks
Rama
