摘要
针对多张裁减曲面的三角化问题,提出一种多张裁减曲面三角化边界的算法。该算法在进行多张裁减曲面的三角化时,采用点对应的方法离散曲面的公共边界,因而能有效地防止曲面相交处出现裂缝、孔洞和覆盖等现象,提高了多张裁减曲面三角化算法的正确性。同时采用了目前比较先进的基于局部优先的平面任意区域三角剖分算法,因而提高了三角化的效率。
An algorithm for triangulation of multi trimmed surfaces is introduced.By corresponding points of common border of the two surfaces,the common border is dispersed,which may effectively prevent cracks,holes and overlap be-tween surfaces,and improve the accuracy of the algorithm for triangulating trimmed surfaces.At the same time ,this pa-per adopts an advanced algorithm triangulation of arbitrary planar domains based on Local Priority to triangulate pa-rameter domain of surface,which improves the efficiency of the algorithm for triangulating trimmed surfaces.
