曲面展开算法的发展现状

Dvelopment and Status Quo of Sufaces Flattening Method

本文主要讨论3D三角形曲面展开成对应的2D平面的问题。将三维曲面转化为二维平面的工作,是很多CAD/CAM系统(如制鞋、成衣、模局制造等)的重要功能之一,它能够将产品的立体曲面自动展开而获得产品资料的平面信息,方便了后来的设计和制造。

This paper elaborates the methods of surfaces flattening. Unfolding 3D surfaces into 2D patterns plays an important role in CAD/CAM systems for most industry applications, such an shoe making, apparel manufacturing, or curved ducts （pipes） production, and most of its solutions usually need a large amount of computations. Thus, to speed up the unfolding process would have significant contribution to the field of CAD/CAM research.
