基于网格的重构曲面再设计中的模板匹配

提出了重构曲面的一种基于三角网格拼接与融合的再设计方法，可方便灵活地实现同类型产品优良设计的结合。提出的网格模板的定位算法保证了网格模板与再设计模型空间位置的匹配；角度匹配算法保证了模板与再设计模型之间最大限度的贴合，为最终再设计网格的构成和再设计曲面的光顺性奠定了基础。这些算法在多个再设计实例中得到应用，取得了良好的效果。

A Convenient and Flexible Redesign Method of Re-Constructed Surface for Combining Existing Excellent Designs

We put forward a redesign method of re constructed surface based on triangular mesh template sewing and fusing. Net template locating and its angle auto matching are important parts of our redesign method. Section 2 discusses net template locating and explains the three steps of doing such locating. The algorithm of net template locating ensures that net template is in correct position relative to redesigned model. Section 3 disusses angle auto matching of net template and explains the three steps of doing such angle auto matching. The algorithm of net template angle auto matching ensures that net template presses closely on redesigned model. Section 4 gives an example of the application of our method; Fig.8 shows the process of redesigning a spoon to meet the requirements of children. Our algorithms have been successfully used in many applications.
