A Bezier triangular patch, based on (u+v+w)^3 = 1, where u, v and w ( = 1 - u -
v) are triangular co-ordinates.

Code in the general group

Using a singular quadrilateral patch could cause problems/wrinkles. However,
trying to smoothly join Bezier triangular patches is even more of a mug's game
than trying to smoothly join Bezier quadrilateral patches since there is only
one internal point
