OpenCascade Sweep Algorithm

     摘要: Abstract. Sweeps are the objects you obtain by sweeping a profile along a path. Sweep is a very useful modeling algorithm. The paper focus on the introduction of the sweep algorithms in the opencascade.

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
