| 摘 要： | 针对快速成形制造中生成实体表面光滑度不高的问题，把细分曲面造型技术应用到快速成形制造中。先定义了顶点平坦度概念，然后对蝶形细分模式进行了改进，用此方法可以直接在初始的三角网格模型上提高模型的表面光滑度而避免了由CAD造形系统重新生成的问题，由此提出了一种可以提高生成实体表面光滑度方法。从光滑度分析和大量的实验结果可以看出，该方法可有效地提高实体表面光滑度，并具有较好的稳定性。

| Abstract: | In rapid prototyping, triangular meshes are the major shape representations that are usually generated by CAD system. One of the major problems in the field of rapid prototyping is the surface smoothness of prototyped objects. To solve this problem, a new method is proposed based on adaptive Butterfly subdivision scheme. The method can directly refine meshes without referring to their original CAD models, and thus can be used inside a prototyping system. A prototype system is developed and some examples are demonstrated. The results show that the method can improve the surface smoothness of the prototyped objects. |
