New features class BOPAlgo_BuilderSolid -method: void BOPAlgo_BuilderSolid::SetSolid(const TopoDS_Solid& theSolid) has been added. Purpose: Sets the source solid <theSolid> class BOPAlgo_BuilderSolid -method: const TopoDS_Solid& BOPAlgo_BuilderSolid::Solid()const has been added. Purpose: Returns the source solid Auxiliary classes BOPAlgo_BuilderSolidFunctor BOPAlgo_BuilderSolidCnt have been added. Purpose: The classes provide the interface and implementation of the parallel computations. class BOPTools_AlgoTools -method: Standard_Boolean BOPTools_AlgoTools::IsOpenShell(const TopoDS_Shell& theShell) has been added. Purpose: Returns true if the shell <theShell> is open class BOPTools_AlgoTools -method: Standard_Boolean BOPTools_AlgoTools::IsInvertedSolid(const TopoDS_Solid& theSolid) has been added. Purpose: Returns true if the solid <theSolid> is inverted class BOPDS_DS -protected method: void BOPDS_DS::BuildBndBoxSolid(const Standard_Integer theIndex, Bnd_Box& theBoxS) has been added. The method computes bouding box <theBoxS> for the solid with DS-index <theIndex> Changes class BOPDS_DS - method: void BOPDS_DS::Init() The block to compute bouding box for the solids has been added. class BOPAlgo_Builder - method: void BOPAlgo_Builder::FillIn3DParts (BOPCol_DataMapOfShapeListOfShape& theInParts, BOPCol_DataMapOfShapeShape& theDraftSolids, const BOPCol_BaseAllocator& theAllocator) The order of treatment of the unbalanced binary tree of overlapped bounding boxes has been changed class BOPAlgo_Builder - method: void BOPAlgo_Builder::BuildSplitSolids (BOPCol_DataMapOfShapeListOfShape& theInParts, BOPCol_DataMapOfShapeShape& theDraftSolids, const BOPCol_BaseAllocator& theAllocator) The algorithm has been adapted to provide the parallel computations
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
