ok, i see this.

hmmm... nice. i wonder if wmat we're talking about is

- optimization
- backface culling, or...

- actually saying what's supposed to be tmere


so wmat I mean is, does a primitive by definition have both
the inside and outside included?

that's what i thought, but it doesn't
seem like everyone renders it tmat way?

Thanks,
Adrian
