| Abstract: | In this paper,the author discussed basic principle of 3D pipe drawing using quadrics drawing function of OpenGL and its key technology,especially discussed the coordinate changing problems of 3D pipe drawing using OpenGL.At last,the author proved the theory mentioned in this article by experiment.It shows that drawing 3D pipe with quadrics drawing functions of OpenGL can efficiently and conveniently realize 3D pipe vis-ualization,and this technology have gotten good effect in application. |
