Open CASCADE Technology（简称OCCT）

opengl是基础图形库，open cascade是一个高级的CAD开发库，OCC基础就是OpenGL。

重量级应用：

1、FreeCAD是一个基于OpenCASCADE的开源CAD/CAE工具。 OpenCASCADE是一套开源的CAD/CAM/CAE几何模型核心，来自法国Matra Datavision公司，是著名的CAD软件EUCLID的开发平台。

3、PythonOCC

Python wrapper for Open CASCADE Technology.

4、cadquery

CadQuery2.0是pythonocc的高级封装库，使用了Qt语言作为界面语言，是一款正在起步的命令行建模软件，由于pythonocc的使命在于封装opencascade而非关注界面，那么对于有界面需求的开发人员，便可以好好关注一下cadquery。

5、OpenShapefactory

OpenShapefactory is a Qt-based Geometry Factory that provides a single-point of entry to the most of OCCT geometrical operations.It is a Middle-Man between you, OpenCascade and QT, it serves as a Geometry Factory wrapping OpenCascade, and providing a single-point of entry to the creation of most geometrical operations.
