jit.gl.nurbs	External		Generate NURBS surface The jit.gl.nurbs object renders a Non-Uniform Rational B-Spline (NURBS) surface. A NURBS is a mathematical model that lets you represent virtually any desired shape, from points, straight lines, and polylines to conic sections (circles, ellipses, parabolas, and hyperbolas) to free-form curves with arbitrary shapes. You can also control the shape of a curve a NURBS generates via sets of control points and knots that can be altered to control smoothness and curvature. A NURBS surface is also an economical way to represent complex shapes with very little data.
