Also, don't forget that there are several PHIGS/PHIGS+ literate folks
who monitor comp.graphics; I for one have answered several P/P+
questions on specific routines or methods for accomplishing a given
effect.

For instance, what's the best way to make something invisible within your
structure?  Depends.  You can use structure editing, name sets and the
invisibility filter, model space clipping (if supported by the
implementation), post/unpost with separate structure and probably
more.

There are usually several ways of accomplishing the same effect under
PHIGS/PHIGS+ and the difference in performance may vary under a given
implementation (and across platforms).
