C++ 应用程序性能优化

     摘要: 对于几何造型内核OpenCASCADE，由于会涉及到大量的数值算法，如矩阵相关计算，微积分，Newton迭代法解方程，以及非线性优化的一些算法，如BFGS，FRPR，PSO等等用于多元函数的极值求解，所以这些数值算法的性能直接影响系统的性能。软件的性能优化是计算机软件开发过程中需要一直关注的重要因素，因此有必要学习下C++应用程序性能优化的方法。  阅读全文

Make Helix Shape in occQt

     摘要: PCurve is a powerful modeling method, to make helix shapes in occQt to help you understand pcurve better, then you can also can model some intereting shape based on pcurve.

OpenCASCADE does not provide helix curve directly, but you can build a helix curve by the pcurve of a surface(curve on surface). When you understand the pcurve of a surface, you can make a helix curve easily.
