OpenCascade Preliminaries Introduction Open CASCADE Technology is a powerful open source C++ library, consisting of thousands of classes and providing solutions in the area of Surface and solid modeling : to model any type of object, 3D and 2D visualization : to display and animate objects, Data exchange : to import and export standard CAD formats, Rapid application development : to manipulate custom application data. and in many others in CAD/CAM/CAE, not excluding AEC, GIS and PDM. Open CASCADE Technology is designed for industrial development of 3D modeling, numeric simulation and visualization applications which require guaranteed quality, reliability and a robust set of tools. Open CASCADE Technology libraries are distributed in open source for multiple platforms, and protected by Open CASCADE Public License which allows unconditional commercial usage of our code and binaries.

The definition of this object determines the way it can be used.Data types fall into two categories according to the way they are manipulated : either by value, or by reference (poin
