三次样条插值，B曲线等都是根据已知样点，用不同方法拟和曲线、曲面。-Cubic spline interpolation, B curves are the basis of known samples, using different methods of curve fitting, surface.

这是基于B样条的曲面构建程序，开发环境是matlab,欢迎下载。-This is based on B-spline surfaces to build the program, the development environment is matlab, welcome to download.
