立体表面展开的特征分解法

The feature decomposition method for the developments of a surface of a solid

文章根据将一个空间立体模型展开成二维平面图形时,把立体的表面分解成两大类特征表面——凹面和凸面。并根据此特征,将组成立体的所有表面全部识别出来,而且可以利用计算机绘图的方法。

In order to flatten a solid model into 2D surface,this paper puts forward the feature decomposition method, by which the surface of a solid model is decomposed into two feature surfaces, concave and convex faces. Computer graphics is used to animate the feature decomposition and flattening.
