The purpose of this repository is to provide OpenCascade and required dependencies for OCC-CSG. We provide static builds for Linux, macOS and Windows (we only build for x64).

Original Readme:

All file locations mentioned below are relative to the opencascade folder inside this repository.

Open CASCADE Technology

This directory contains sources of Open CASCADE Technology (OCCT), 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 can be best applied in development of software dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical simulation (CAE).

Packaging

You can receive certified version 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 complete source archive, it 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.com

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 accompanying 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) installed on your system. and accessible in your environment (check environment variable PATH). Use batch file gendoc.bat on Windows or Bash script gendoc on Linux or OS X to (re)generate documentation.

• 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
