WebOct 21, 2024 · Curve and surface fitting technology is one of the key technologies of 3-dimensional modeling and 3-dimensional design technique. Based on the B-spline method and the corresponding boundary conditions, the method and steps of a cubic NURBS curve and surface fitting were presented in this paper. And then the algorithm was verified by … WebFirst, we assign a parameter value t i to each point P i. The usual way to do this is to use chord-lengths -- you choose the t i values such that t i − t i − 1 = ‖ P i − P i − 1 ‖. Then you compute x as a function of t. The calculation is the one you already know, but it's just x = f ( t) instead of y = f ( x).
