摘要
利用自适应分片技术把拓扑结构复杂的曲面展开为平面.首先把CAD/CAM常用的参数曲面转化为三角剖分模型,求出曲面的伪直母线;然后基于伪直母线对曲面进行自适应分片;最后展开每一片曲面区域.该算法可以直接应用于计算机辅助设计、制造和计算机图形学的纹理映射,也可以应用于实际工业造型中的后继 处理.
Using an adaptive segment technique, a topological complex 3D surface can be developed into its corresponding 2D pattern. Firstly, triangular facet model is used to present a complex surface, and its quasi-rulings are computed. Secondly, the 3D surface is adaptively segmented based on its quasi-ruling. Finally, each segment is flatted into 2D pattern. This development algorithm can be directly used to computer aided design or texture mapping. It can be also applied to post-process in practical industrial modeling.
