I have just tested on one of the first french IR yesterday an application
that runs good on IndigoČ, Impact and ReČ.
This is a Performer 2.x based app with GL calls. All objects are in
Inventor Format.

Basically, it runs fast but I have noticed several points that I need help
or advice on.
First the machine is IR R10000, irix 6.2 with patches 1243,1252,1282,1295.
Installed performer version is
Perf 2.1 backward DSO
Perf 2.1 Dev software
Perf 2.1 Execution
Perf 2.0.1 Execution ====>(how surprising !!!)

Second, what I have noticed:
- The lod transition seems to act like the one on Impact, just a simple
switch, no fading like on ReČ.
- Alpha texture need to have pfTransparency switched to high instead of fast
like on all other machines ( but it runs so it is no longer a question!).
- Transparency in Inventor geometry is not supported if antialiasing is
switched to on. But if switched to off, I got my transparency. So should I
add pfTransparency high in the Iv loader to get this work ?
- I'm ligthly disapointed on antialiasing, so wath are the tricks to get it
better.

PS: I need fast answers, because the machine should be shipped in the couple
of next days !!!!!

Sumary of the questions:
better antialiasing ?
lod transition with fading ?
Inventor transparency and antialiasing ?

Thanks in advance.
