I'm wondering if/how I can create a bezier surface with more control points
than the limit of 4x4. I need at least 10x10. Can I use an isosurface to do
this? At first I tried to patch an array of  patches together, but of course
the seams are too sharp. I've only seen the equation for bezier curves
before, so I imagine that the equation for a bezier surface has to be more
complicated, maybe too much for an isosurface?

What I'm wanting to do is create a surface with x and z fixed on a plane and
have y variable. The surface is for a graph I'm making. I've thought of
making the surface from triangles. Is it possible to calculate (in POV) the
normals for the points of a triangle?

Anyway that's probably enough questions for now...
