NurbsSurface

class NurbsSurface

A nurbs surface value.

This object is a standard nurbs surface. The control points are stored in u order first

control_points_v()	Return the number of control points in v.
degree_u()	Return the surface degree in u.
degree_v()	Return the surface degree in v.
evaluate(u, v)	Evaluate the surface at a uv coordinate.
evaluate_dp(u, v, previous_u, previous_v)	Evaluate the surface position derivatives at a uv coordinate.
iso_curve(u, use_v)	Extract an iso curve from the surface.
mode_u()	Return the surface degree in u.
mode_v()	Return the surface degree in v.
range_u()	Return the u parameter range.
range_v()	Return the v parameter range.

read_knots_v()	Return the readable surface knots in v.
set_range_u(r)	Set the u parameter range.
set_range_v(r)	Set the v parameter range.
span_u()	Return the number of span in u.
span_v()	Return the number of span in v.
tessellate(subdivision_u, subdivision_v, ...)	Return a mesh out of the nurbs surface, with the uv and normals if requested.
