I don't know that these companies generally make their CAD
environment available to outsiders; my impression is that they have
large systems that have developed and mutated over the past 10+ years
that are heavily customized ofr their applications. If this is the
case, then it is doubtful that they have written their application
with PHIGS in mind, since PHIGS+ and (I think) PHIGS were just dreams
of a standard that didn't exist when they started writing their
PHIGS (when I say PHIGS, lets agree that it means PHIGS/PHIGS+ and
possibly PEX) has only been around for a very short time compared to
the life of these big CAD packages.

See above; PHIGS is so new that people are basically trying to decide
if they should go with GL and the installed base of SGI (and now IBM
RS6000) machines, or go with PHIGS which is what all the other vendors
seem to be doing. People with PHIGS: E&S, Sun, DEC, HP (Apollo), IBM,
etc. People with GL: SGI, IBM. [These lists are certainly

Well, we have MovieStar.BYU on the ESV, but I haven't used it myself.
It's primarly for generation/processing of FEM results via a
traditional FEM package.

Again, PHIGS is so new that the user base today possibly isn't the
best metric. Interestingly enough, Stardent's AVS (Application
Visualization Software) has a PHIGS porting layer and it is at least
several years old.

I have no idea.
