In a Performer program that I'm working on, I need pfGeoSets with
the PFGS_POLYS flag. When creating a geoset like this I fill in
the lengths array with the correct number of vertices for each
polygon. The problem is that perfly crashes on these geosets. I
tried other sample programs and they seem to work.
For testing purposes I created a geoset with triangles but still
used the PFGS_POLYS flag and create a lengths array with all the
values set to 3. The perfly program still crashes on the geoset.
When I change the primtype flag to PFGS_TRIS without changing
anything else perfly seems to work just fine.
My code looks like this:
/******************************/
create coords array, create lengths array (shared arena)
geode = pfNewGeode ();
gset = pfNewGSet (arena);
pfGSetAttr (gset, PFGS_COORD3, PFGS_PER_VERTEX, coords, NULL);
pfGSetPrimLengths (gset, lengths);
pfGSetNumPrims (gset, lengthsCount);
pfGSetPrimType (gset, PFGS_POLYS);
pfAddGSet (geode, gset);
pfAddChild (parent, geode);
/******************************/
I am sure that the coords and lengths arrays are correct. I checked
them using pfPrint. I was wondering if one should do something extra
when using PFGS_POLYS.
Perfly crashes in the following functions. (Note: I did not change
the perfly program, this is the standard version.)
