This kinda stuff is great! Thanks Angel.
(I knew there was a deCastelJau derivation of Triangular
patches but I wasn't going to derive it. :-)

Thanks anyway Dave.  Just FYI, I liked your old site
better since it included papers and references on it
as opposed to source with book purchase.  But I can't
dog you for trying to make a living.

As to Tom Forsyth' quick solution, do you have any
textured screen shots?  Just curious as to what 
that parameterization does to texture mapping.

Thanks all,
