     摘要: Debian是OpenCASCADE用于Linux操作系统测试的专用系统。这几天下载安装了Debian系统,体验了一下,感觉还不错:简洁,精致。

解决了这些问题后,Debian用起来感觉还好,还需要慢慢熟悉和适应。下一步准备在Debian上编译、调试C/C++程序。为编译OpenCASCADE的Linux版本打下基础。  阅读全文

     摘要: Abstract. The color scale is a specialized label object that displays a color map and an accompanying numerical scale for color mapped or contour data plots. As the geometry modeling kernel of SALOME, OpenCASCADE provides the color scale function. The paper focus on the usage of color scale in OpenCASCADE.

     摘要: Abstract. Although polynomials offer many advantages, there exist a number of important curve and surface types which cannot be represented precisely using polynomials, e.g., circles, ellipses, hyperbolas, cylinders, cones, spheres, etc. So we introduce the concepts of rational curves and homogeneous coordinates to solve the problem. To understand rational curves in a homogenous coordinate system is more straightforward. If you define irrational Bezier curves in 4D space and then project them ba  阅读全文

     摘要: Abstract. Numerical integration is the approximate computation of an integral using numerical techniques. The numerical computation of an integral is sometimes called quadrature. The most straightforward numerical integration technique uses the Newton-Cotes formulas(also called quadrature formulas), which approximate a function tabulated sequence of regularly spaced intervals by various degree polynomials. If the functions are known analytically instead of being tabulated at equally spaced inter  阅读全文

     摘要: Abstract. Doxygen is the de facto standard tool for generating documentation from annotated C++ sources, but it also supports other popular programming languages. You can also use doxygen for creating normal documentation, as OpenCASCADE did for its references and user’s guide documents.
