Open CASCADE Technology

Open CASCADE Technology (OCCT) is a software development platform providing services for 3D surface and solid modeling, CAD data exchange, and visualization. Most of OCCT functionality is available in the form of C++ libraries. OCCT is ideal for developing software dealing with 3D modeling (CAD), manufacturing/measuring (CAM), or numerical simulation (CAE). You can receive certified versions of OCCT code in different packages: Snapshot of Git repository: Contains C++ header and source files of OCCT, documentation sources, build scripts, and CMake project files. Complete source archive: Contains all sources of OCCT, generated HTML and PDF documentation, and ready-to-use projects for building on all officially supported platforms. Binary package (platform-specific): In addition to the complete source archive, it includes binaries of OCCT and third-party libraries built on one platform. This package allows using OCCT immediately after installation. You can also find OCCT pre-installed on your system or install it from packages provided by a third party. Note that packaging and functionality of such versions can be different from certified releases. Please consult the documentation accompanying your version for details. If HTML documentation is not available in your package, you can: Generate it from sources: You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system and accessible in your environment (check the environment variable PATH). Use the batch file adm/gendoc.bat on Windows or the Bash script adm/gendoc on Linux or OS X to (re)generate documentation. Generate together with sources: You need to have CMake and 1.8.4 (or above) installed on your system. Enable BUILD DOC Overview CMake parameter and set the path to Doxygen 3RDPARTY DOXYGEN EXECUTABLE . Then build ALL or only Overview . Read documentation in source plain text (Markdown) format found in the subfolder dox or GitHub Wiki. Consult the file dox/build/build occt/building occt.md or Building OCCT or Building OCCT Wiki for instructions on building OCCT from sources on supported platforms.
