摘要
介绍了NURBS构造二次曲面(圆锥面为例)的方法,并且在VC环境下,基于OpenGL实现对曲面控制点的修改.与传统Bezier曲面的修改相比,NURBS修改控制点或权因子更方便。
The method for the architecture of quadrics by NURBS is introduced. Modification of control points of the quadrics based on OpenGL is realized. Compared with the traditional modification of Bezier quadrics, modification of control points and weighting factors by NURBS is more convenient.
