Description: 三次B样条插值曲面及其实现::目前在ＣＡＭ／ＣＡＭ的自由曲面构造方法中，较流行的有Ｂ样条曲面，Ｂｅｚｉｅｒ曲面、Ｂａｌｌ曲面等方法，但由这几种方法和成都是拟合曲面，而百插值曲面，常常不能满足一些工程实际中严格插值的要求，本文构造了一种自由插值曲面生成方法－Ｂ样条母线法，所生成曲面达到Ｃ＾２级光滑，适用机械，模具、汽车、造船等制造加工行业的复杂曲面设计。-Three B-spline interpolation surface and realize:: At present CAM/CAM method of constructing the free-form surfaces, the more popular has B-spline surfaces, Bezier surfaces, Ball surfaces and so on, but by the several methods and Chengdu is surface fitting, and interpolation surface hundred, and often can not meet a number of engineering practice, the requirements of strict interpolation, this paper constructed a free interpolation surface generation method-B-spline busbar law, generated by C ^ 2 surface to achieve a smooth level applicable to machinery, tooling, automotive, shipbuilding and other manufacturing industries processing complex surface design.

Description: 这是一个三次样条插值的.m程序
输入的是一个二维数组A(Nx2)
插值方法为:
S(x) = A(J) + B(J)*( x - x(J) ) + C(J)*( x - x(J) )**2 +D(J) * ( x - x(J) )**3 for x(J) <= x < x(J + 1) -This is a cubic spline interpolation. M program input is a two-dimensional array A (Nx2) interpolation method: S (x) = A (J)+ B (J)* (x- x (J ))+ C (J)* (x- x (J))** 2+ D (J)* (x- x (J))** 3 for x (J) Platform: |
