Open CASCADE Technology ======================= This directory contains sources of Open CASCADE Technology (OCCT), a collection of C++ libraries providing services for 3D surface and solid modeling, CAD data exchange, and visualization. OCCT can be best applied in development of software dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical simulation (CAE). License ------- The OCCT code is subject to the Open CASCADE Technology Public License (the "License"). You may not use the content of the relevant files except in compliance with the License. Please see the LICENSE file or obtain a copy of the License at http://www.opencascade.org and read it completely before using this software. Packaging --------- You can receive certified version of OCCT code in different packages. - Snapshot of Git repository: contains only bare sources of OCCT; many C++ files, HTML documentation, and project files / makefiles for building OCCT need to be generated. - Complete source archive: contains all sources of OCCT, including C++ files generated by WOK, HTML and PDF documentation, and projects / makefiles for building on all officially supported platforms. - Binary package (platform-specific): in addition to complete source archive, includes binaries of OCCT and third-party libraries built on one platform. This package allows using OCCT immediately after installation. Certified versions of OCCT can be downloaded from http://www.opencascade.org 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 documentation accompanyog your version for details. Documentation ------------- Open file doc/html/index.html to browse HTML documentation. 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) in PATH. In Tcl prompt, cd to OCCT root folder and run "source dox/start.tcl". On Windows you can also run shortcut batch file *gendoc.bat*. - Read documentation in source plain text (MarkDown) format found in subfolder *dox* See *dox/dev_guides/documentation/documentation.md* for details. Building -------- In most cases you need to rebuild OCCT on your platform (OS, compiler) before using it in your project, to ensure binary compatibility. Consult the file *dox/dev_guides/building/building.md* for instructions on building OCCT from sources on supported platforms. Version ------- The current version of OCCT can be consulted in the file *src/Standard/Standard_Version.hxx* Development ----------- For information regarding OCCT code development please consult the official OCCT Collaborative Development Portal: http://dev.opencascade.org
