As for the non-uniform and common sense I would suspect they also talk about obscuring mathematical properties of NURBS that helps create a realistic curved surface. In the late 1800s man with splines began to control lines between two points and the fact that lines produced with equally resilient small draft splinters also met the mathematical definition of splines especially the curve between two points having continuous first and second derivatives. From: Internet-based splines: Building network-based functions defined at separate intervals while approaching the network and sampling pieces of simple operations defined subintervals and ending their endpoint with appropriate degree smoother. ![]() ![]() ![]() Suffice it to say computer graphics include a lot of food and methodological tricks that are used to get everything to run fast enough to be acceptable is very impressive.
