Hi everybody!
I'm currently working with the GLU tesselator and I need the ability
to abort a tesselation process at any state, as fast as possible (so
calling gluTessEndPolygon is not an option). Additionally i would like
to be able to re-use the GLUtesselator object afterwards.
Is the following addition to the API sufficient to do that, or am I
missing something?
/* glu.h */
GLAPI void GLAPIENTRY gluTessAbort (GLUtesselator* tess);
/* tess.c */
void GLAPIENTRY
gluTessAbort( GLUtesselator* tess )
{
MakeDormant( tess );
}
Few of us have ever dug into the internals of the tessellator so you
probably know as much about it as anyone here.
If you're going to add a new entrypoint to GLU for your project I
think you have two options:
1. If you want the change to go into the Mesa/GLU tree and distro,
spec-out a new GLU_MESA_tessellation_abort extension.
2. Pull a copy of the GLU tessellator into your project and hack away
as needed.

Thanks for the info, I'll stick with 2) for now, lets see how it works.
If I find someone familiar with the tesselator (or work long enough with
it to fully understand it) I might register an extension. (I've never
done that, but it sounds like an exciting thing to do, especially for a
student :))
