Open Cascade Technology
Open Cascade Technology (OCCT, formerly named CAS.CADE) is an object-oriented C++ class library for 3D computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), etc. It is developed and supported by Open Cascade SAS company. It is free and open-source software released under the GNU Lesser General Public License (LGPL), version 2.1 only, which permits open source and proprietary uses.
OCCT is a full-scale boundary representation (B-rep) modeling toolkit.
CAS.CADE (abbreviated from Computer Aided Software for Computer Aided Design and Engineering) was originally developed in the early 1990s by Matra Datavision, developer of Euclid CAD software as the underlying infrastructure for its future version Euclid Quantum. In 1998 the company abandoned software development to concentrate on services, and most of the software development facilities were sold to Dassault Systèmes, developer of competing CATIA.
In 1999 Matra Datavision decided to publish its CAS.CADE infrastructure under an open-source model under the Open CASCADE Technology Public License and renamed it Open Cascade.
In 2000, a separate company, Open Cascade SAS, was created to make business around Open Cascade. Open Cascade SAS was sold in 2003 to Principia, a French service provider corporation, and then in 2006 it was acquired by Euriware Group, a subsidiary of Areva.
In 2004, software was renamed to Open Cascade Technology in order to distinguish it from the name of the company itself.
Open Cascade S.A.S. provides a certified version of the library, which is released sporadically, usually 1–2 releases per year. Until version 6.5.0 (2011), only minor and major versions were publicly available, while intermediate (maintenance) releases were accessible only to customers of Open Cascade S.A.S. For example, version 6.3.0 was publicly released in 2008, and the next public version 6.5.0 was released in early 2011. All recent releases starting from version 6.5.0 are public.
In March 2011, Thomas Paviot initiated a fork of the then most recent publicly available version 6.5.0 of Open Cascade library. The initiative is named Open Cascade Community Edition. The project aims to establish a separate community-based release and bug-report process for the library.
