OpenCASCADE AIS Manipulator

     摘要: Abstract. OpenCASCADE7.1.0 introduces new built-in interactive object AIS_Manipulator providing interface for moving objects within 3D viewer. The class features three kinds of transformation modes for attached objects: translation through axis, scaling within axis, rotation around axis. The object can be activated using vmanipulator command within Draw Test Harness.

OpenSceneGraph in ActiveX by ActiveQt

     摘要: Abstract. Qt’s ActiveX and COM support allows Qt for Windows developers to access and use ActiveX controls and COM objects provided by any ActiveX server in their Qt applications. Make their Qt application available as COM servers, with any number of Qt objects and widgets as COM objects and ActiveX controls. Make OpenSceneGraph to ActiveX controls then you can use it in other place, like IE.

OpenCASCADE Shape Location

     摘要: Abstract. The TopLoc package of OpenCASCADE gives resources to handle 3D local coordinate systems called Locations. A Location is a composition of elementary coordinate systems, each one is called a Datum. The Location keeps track of this composition. The paper will use the Draw Test Harness to illustrate the Location concept.

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.

OpenCASCADE Expression Interpreter by Flex & Bison

     摘要: Abstract. OpenCASCADE provide data structure of any expression, relation or function used in mathematics. Flex and Bison are tools for building programs that handle structured input. They were originally tools for building compilers, but they have proven to be useful in many other areas. The Expression Interpreter in OpenCASCADE is made by Flex and Bison. So let’s know something about Flex and Bison.
