This branch contains fixes for 26675 and 26431 bugs. 1. Normalization has been eliminated. 2. Interfaces of AppDef_Compute::Parametrization(...) and BRepAlgo_BooleanOperations::SetApproxParameters() methods have been changed. 3. Overloaded methods for ApproxInt_Approx::SetParameters(...), TopOpeBRepTool_GeomTool::GetTolerances(...) and TopOpeBRepTool_GeomTool::SetTolerances(...) have been removed (because some fields of these classes are not used more). 4. Comments for some methods have been changed in BRepApprox_TheMultiLineOfApprox.hxx and GeomInt_TheMultiLineOfWLApprox.hxx files. 5. Some fields have been deleted from ApproxInt_MultiLine class. Kept members have become constant. 6. Interface of ksection DRAW-command has been changed. 7. Now, 2dintersect DRAW-command prints information about found segments. 8. Some code fragments have been rewritten to make them easier. 9. Algorithm of splitting WLine, which goes through pole of sphere has been improved. 10. Improve approximation algorithm in order to it will compute correct 2D- and 3D-tangent at the end of bezier constraints (including case when curve goes through or finishes on singular points). 11. Interface of IntPatch_WLine::Dump(...) method has been corrected. 12. Some methods for working with Walking-line are made more universal (available for both GeomInt and IntTools packages). 13. Problem in BRepLib::SameParameter(...) method has been fixed (see corresponding comment). 14. Small correction in Draft package. 15. Any outputs in IntPatch_Intersection::Dump(...) method have become disabled because they are useless. If anybody need in this outputs he/she will correct this method himself/herself. Adjusting some test cases according to their new behavior. Creation of new test cases. ---------------------------------------------------------------------------------------------------------------------------- Some explanation of new behavior of some test cases: 1. Regressions: a) blend simple X4 The problem is described in the issue #0026740. According to this description, the result on the current MASTER seems to be wrong indeed. b) boolean bcommon_complex C7 and boolean bcut_complex Q1 These test case use same shapes with different Boolean operation (COMMON and CUT). They are already BAD (on the MASTER). Now, some sub-shapes have become not-shared, simply. In my opinion, we shall apply new behavior of these tests. c) boolean bsection M3 The problem described in the issue #0026777 exists even on the current MASTER. d) boolean bsection M9 The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=26815#c47546. Here, we have really regression in the picture. e) boolean bsection N2 The problem is described in issue #0026814. f) boolean volumemaker G1 The problem is described in issue #26020. g) bugs modalg_1 bug1255 (and bug1255_1) The problem is described in issue #26815. h) bugs modalg_2 bug5805_18, bugs modalg_2 bug5805_42, bugs modalg_2 bug5805_46 The problem is described in issue #25925. i) bugs modalg_3 bug602 The problem is describes in issue #602. j) bugs modalg_5 bug24915 The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=25929#c48565. It is not fixed by this issue. k) bugs modalg_5 bug25838 The main reason is described in issue #0026816. ---------------------------------------------------------------------------- 2. Improvements: a) boolean volumemaker F9 b) bugs modalg_1 bug10160_3 c) bugs modalg_2 bug22557 d) bugs modalg_5 bug25319_1 (_2) e) draft angle G2 f) offset shape A1 g) offset with_intersect_80 N7
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
