OpenCASCADE中散乱Edge生成Wire

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

Boolean operations between triangle meshes

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

OpenCASCADE Trihedron Law

摘要: 曲线的活动标架是《微分几何》中一个很基础的概念。有了曲线的活动标架，扫掠造型Sweep算法的实现有了一些思路。当给定一个轮廓线后，将轮廓线沿着路径曲线扫掠可以理解为将轮廓线变换到曲线的活动标架中。本文主要演示了Frenet活动标架的例子，读者可以将GeomFill_TrihedronLaw其他的子类表示的其他类型活动标架自己实现，加深理解。阅读全文
