http://nurbscalculator.in/ WebOpenGL (and our friend JOGL) supports NURBS and Bezier curves and surfaces. Though NURBS are more interesting and more useful, they are also more complex to use and we don't have a lot of time, so we will just work with Bezier splines. These are relatively straightforward to use. You need control points -- 4 for a line segment, 16 for a patch.

WebWith OpenGL, you must build up your desired model from a small set of geometric primitives - points, lines, and polygons. A sophisticated library that provides these features could certainly be built on top of OpenGL. The OpenGL Utility Library (GLU) provides many of the modeling features, such as quadric surfaces and NURBS curves and surfaces.
