基于均匀B样条的犁体曲面造型设计

Modeling design of plow surface based on uniform B spline

以水平直元线法的犁体曲面形成原理提取型值点,用均匀B样条曲线反算公式反算数列控制点,用均匀B样条曲面正算公式定义犁体曲面并裁剪。用Visual C++和OpenGL进行程序实现。

To pick up the nodal points according to the generative principle of plow surface with the horizontal straight generatrix method, to counter calculate the controlling points of progression by the use of uniform B spline curve of counter calculating formula, and to make definition and cut out of plow surface with uniform B spline surface positive calculation formula. To carry out the realization of program by the use of Visual C＋＋ and OpenGL.
