| 摘 要： | 三维空间关系比二维要复杂得多,它们的缓冲分析功能也多是基于二维数据运算,基本没有实现构建管线实体的三维缓冲体,非真正意义上的三维缓冲分析。该文采用断面与体面三角剖分拟合的方法,基于OpenGL构建了管线实体的点、线、体的三维缓冲体模型,实现了管线实体的缓冲体分析,验证了缓冲体分析算法的有效性和正确性。

| Abstract: | Threedimensional relationship is much more complex than twodimensional. The buffer analysis of their functions is also operated based on twodimensional datas.3D buffer pipeline construction has not been realized entirely. It is not real analysis of 3D buffer. In this paper, by using the method of cross section and decent triangulation fitting, 3D model including buffer pipeline point, line and body has been constructed based on OpenGL. It has realized the analysis on pipeline buffer entity, and verified the correctness and effectiveness of buffer analysis algorithm. |
