BRepMesh_Classifier: Two-pass approach for intersection check with possibility to run it in parallel mode. First pass - bounding boxes of segments are checked for overlapping; Second pass - intersection point is calculated in case if overlapping is detected. Make NCollection_UBTree::ChangeLastNode() exported due to compilation error on Linux platform. Reason: method does not depend on template parameters, so it should be available. Revert previous change and try to use another trick for Linux Fix compilation warning on MacOS: remove redundant constant Fix regressions: do not consider insignificant loops in case of self intersections on the same wire. More sugar solution for compilation errors on NCollection_EBTree on Linux Test cases for issue CR24968
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). License ------- Open CASCADE Technology is free software; you can redistribute it and / or modify it under the terms of the GNU Lesser General Public version 2.1 as published by the Free Software Foundation, with special exception defined in the file OCCT_LGPL_EXCEPTION.txt. Consult the file LICENSE_LGPL_21.txt included in OCCT distribution for complete text of the license. Alternatively, Open CASCADE Technology may be used under the terms of Open CASCADE commercial license or contractual agreement. Note that Open CASCADE Technology is provided on an "AS IS" basis, WITHOUT WARRANTY OF ANY KIND. The entire risk related to any use of the OCCT code and materials is on you. See the license text for formal disclaimer. 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, 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.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) installed on your system. and accessible in your environment (check environment variable PATH). Run batch file *gendoc.bat* on Windows or Bash scriot *gendoc.sh* on Linux or Mac 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* Development ----------- For information regarding OCCT code development please consult the official OCCT Collaborative Development Portal: http://dev.opencascade.org
