Hello Performers !
We are anticipating same problem as faced by Mr.Tapio Hellman for running
the Cat2pfb utility in CATIA V5 R13/R14 running on Onyx4 Ultimate vision.
My questions are :-
1.0 What would be the solution if CATIA V4 installation and licensing are
not there ?
2.0 What are the other options if we want to convert and load the CATIA V5
large assemblies
in to performer bench.
3.0 When CATIA V5 will be certified on Onyx4 Ultimate Vision ?
Best regards,
Avik Chatterjee.

> We would like to visualize large CATIA V5R14 models in our CAVE running
SGI Onyx4 with 6 pipes and 14G of memory, which should be quite enough for
even large models. Since CATIA Enovia DMU Review is not yet certified on
Onyx4 and out Walkinside CATIA converter is not working properly i just
thought that visualizing CATIA model with Performer based apps like Saranav
might save us. Exporting these CATIA models to VRML files is not a solution,
since these models are quite large and the way round objects are handled in
VRML output is so poor for realtime visualization. VRML files just fill up
with thousands of useless polygons, which crowd the OpenGL pipes and we get
a frame rate of 0,1 seconds or even worse with VRScape or COVER, which can
read VRML models. So we must find a better file format for realtime
visualization of large models. If Performer Fast Binary pfb may tesselate
these round objects in more sensible way, we might be able to use Saranav or
COVER for the visualiza!

cat2pfb
(http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=0650&db=man&fna
me=/usr/share/catman/u_man/cat1/Performer_demo/cat2pfb.z) since Performer
3.1, but after converting out CATIA V5 CATProducts to CATIA V4 models, I
found out that since CATIA V4 is not installed in our IRIX system (CATIA
V5R14 is), the converter does not work. First error message was "Missing
STEPLIB environment variable" and when I "fixed" that the second message was
"Missing SYMLIB". It seems that CATIA V4 or at least some parts of it must
be installed, as it is said in the document
http://www.sgi.com/products/software/performer/faq.html#14.

> Which parts of CATIA V4 must be there in order to be able to run the
converter?
> If we are able to get those library files needed from Dassault Systemes
(which might be a problem since we do not have a license for V4 but only to
V5), will the converter ever run on Onyx4, which is not (yet?) a certified
platform for CATIA?
