[Algorithms] Bezier Triangle Rendering

[Dave S. <Dav...@sd...>]

I can compute points on a Bezier Triangle,
but I'm having a tough time coming up with
a good tessellator for it.  Are there any
references that has a demonstration of this?

I'm currently looking at fixed subdivision for 
the quadratic case, but because its not bi-quadratic 
in the square sense, like bezier patches, it's harder 
to come up with an easy algo for producing the parameter
space points.

Any ideas or pointers would be much appreciated,
Thanks,

Conor, that sure was a "wacky" patent. :-P
