Remove unused flag "DoubleBuf". Remove Visual3d_TransientManager "class" (functionality moved to PrsMgr_PresentationManager). Remove unused "Add" immediate mode. V3d_View class - remove methods ::TransientManagerBeginDraw(), ::TransientManagerClearDraw(), ::TransientManagerBeginAddDraw(). Add method ::RedrawImmediate() to redraw only immediate presentations. OpenGl_GraphicDriver - add methods ::DisplayImmediateStructure(), ::EraseImmediateStructure(), ::RedrawImmediate(). OpenGl_View - manage list of immediate structures. OpenGl_Workspace - automate rendering workflow of immediate + persistent layers. Merge PrsMgr_PresentationManager3d class into PrsMgr_PresentationManager. Mark PrsMgr_PresentationManager3d as alias to PrsMgr_PresentationManager to simplify porting. Prs3d_Presentation - remove unused field myStruct. Prs3d_PresentationShadow - shadow link to existing presentation with custom attributes. Graphic3d_Structure::Highlight() - do not register undisplayed structure in structure manager. AIS_InteractiveContext, AIS_LocalContext add flag to prevent view update into methods ::MoveTo(), ::HilightNextDetected(), ::HilightPreviousDetected() to allow update of customized immediate structures before redraw but after ::MoveTo(). Remove unused method AIS_InteractiveContext::Drag(). StdSelect_ViewerSelector3d do not user immediate mode in methods ::DisplayAreas(), ::ClearAreas(), ::ClearSensitive(), ::DisplaySensitive(), GridEcho - update value in StdSelect_ViewerSelector3d::Pick() instead of V3d_View::Compute(). Do not use global variable for GridEcho vertex. Redraw immediate mode not within GridEcho but at AIS_InteractiveContext, AIS_LocalContext layer. V3d_View::ToPixMap() - disable autoupdate during FitAll. Avoid Redraw() into FBO without ImmediateModeDrawToFront flag. PrsMgr_PresentationManager stores list of temporary immediate presentations, automatically cleared within BeginImmediateMode() call. Methods with ambiguous names have been renamed (new names now consistent with pre-existed method names in AIS_LocalContext class): - BeginDraw -> BeginImmediateDraw - EndDraw -> EndImmediateDraw Remove now useless Remove() method (and ImmediateRemove() in AIS). Visual3d_View now stores map of displayed immediate presentations. ViewerTest_EventManager - eliminate double redraw in selection methods. Fix warning
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.

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
