| 摘 要： | 本文提出了一种基于双三次Ｂｅｚｉｅｒ曲面的双三角平面模型，并以此模型为基础建立了相应的平化判别、分割求交算法。采用主动边与被动三角平面间的遍历来获得交线。与多边型模型相比双三解平面模型具有理论严密，简法简捷、近似度好、节省时空等优点。

| Abstract: | In this paper, the bitriangle plane model that is baseed on the parametricbicubic segment of Bezier-type is proposed. Compared with the polygon approximatemodel, the bitriangle plane model theory is more compact, its algorithm is moresimple and direct, and it has good approximation.According to this model, we establish a seriws of algorithms of segmentation. Withefforts all.above, we have achieved curved surfaces segmentation and intersectionon micro-computer initially. |
