1 Open CASCADE Technology
2 =======================
4 This directory contains sources of Open CASCADE Technology (OCCT), a software
5 development platform providing services for 3D surface and solid modeling, CAD
6 data exchange, and visualization. Most of OCCT functionality is available in
7 the form of C++ libraries. OCCT can be best applied in development of software
8 dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical

30 You can receive certified version of OCCT code in different packages.
32 - Snapshot of Git repository: contains C++ header and source files of OCCT,
33 documentation sources, build scripts, and CMake project files.
35 - Complete source archive: contains all sources of OCCT, generated HTML and PDF
36 documentation, and ready-to-use projects for building on all officially
39 - Binary package (platform-specific): in addition to complete source archive,
40 it includes binaries of OCCT and third-party libraries built on one platform.
41 This package allows using OCCT immediately after installation.
43 Certified versions of OCCT can be downloaded from http://www.opencascade.com
45 You can also find OCCT pre-installed on your system, or install it from
46 packages provided by a third party. Note that packaging and functionality
47 of such versions can be different from certified releases. Please consult
48 documentation accompanying your version for details.
53 Open file doc/html/index.html to browse HTML documentation.
55 If HTML documentation is not available in your package, you can:
57 - Generate it from sources.
59 You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system.
60 and accessible in your environment (check environment variable PATH).
61 Use batch file *gendoc.bat* on Windows or Bash script *gendoc* on Linux
62 or OS X to (re)generate documentation.
64 - Read documentation in source plain text (MarkDown) format found in
67 See *dox/dev_guides/documentation/documentation.md* for details.
72 In most cases you need to rebuild OCCT on your platform (OS, compiler) before
73 using it in your project, to ensure binary compatibility.
75 Consult the file *dox/dev_guides/building/building.md* for instructions on
76 building OCCT from sources on supported platforms.
81 The current version of OCCT can be consulted in the file
