OpenGL(15)GLU库API

本文主要是介绍OpenGL(15)GLU库API，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

/****           Backwards compatibility for old tesselator           ****/
//定义一个非凸多边形 
void APIENTRY   gluBeginPolygon( GLUtesselator *tess );
//为其他轮廓的开始做标记 
void APIENTRY   gluNextContour(  GLUtesselator *tess, GLenum        type );
//定义一个非凸多边形 
void APIENTRY   gluEndPolygon(   GLUtesselator *tess );
