     摘要: 在OpenCASCADE中生成WIRE时要求添加到WIRE中的边EDGE是有顺序要求的。当给定的边没有按顺序添加到WIRE之前,需要自己将EDGE按顺序处理。OpenCASCADE中也提供了对EDGE按顺序进行排序的功能,方便WIRE的生成。
  本文给出将散乱的EDGE排序后生成WIRE的实现代码,这个功能用处还是很大的。  阅读全文

     摘要: OpenCASCADE提供了基于BREP体的Boolean Operations,但是如果Topo体中只包含三角网格信息的话,是不支持布尔运算的。典型的例子就是由STL导入生成的模型在OpenCASCADE中是不能进行布尔运算。

有一些开源库提供了基于三角网格的布尔运算的功能。如MeshLab、Cork等。本文主要就来介绍一下这两个库中的基于三角网格的布尔运算功能。  阅读全文
