Hi Brian,

> Would Newton-Raphson solver, with Jacobians be able to find the U,V values?

Yup, those are some of the techniques used in solver mechanisms. The geometry library MoI uses has various kinds of solvers implemented, just the only part exposed to scripts at the moment are things in the area of "evaluators" which go from parameter space to 3D space.


> So the 2 dimensional UV space is a rectangular grid?

Yup, and basically the fundamental definition of NURBS surfaces is a mechanism that evaluates a 2D point in that UV space to produce a 3D point.
