摘要
给出一种满足二阶连续的平面网格细分算法 ,该算法利用三次 B- Spline曲线的分割作图思想 ,计算简单 ,效果好 ,已被成功地应用于多个系统中 .尤其在服装试衣效果 CAD中有着特殊的意义 ,解决了衣片的网格划分 .纹理映射结果能逼真地反映衣服的褶皱、明暗、垂感 ;最难描述的裙装、弯曲的袖及裤得到了有效的解决 .该算法将大大改进服装试衣效果 CAD技术 ,在相关领域也有着广泛的应用前景和很强的商业价值 .
A 2D grid subdivision algorithm based on C 2 is given. Although using the segmentation ways of 3 order B Spline curve and surface, it has been applied successfully in several system owing to compute much easily and effect precision. Especially, in the garment effect simulation CAD(CGASD) it resolves piece subdivision and texture mapping which is the most complicated problem and difficult to present drape, shade and lop affect. With advanced rapidly CGASD, the shortcut, exact and consecutive algorithm has commercial value.
