Expose interface of OpenGl_View (OpenGL graphics rendering methods) to client code and collecting all high-level API methods of application views in V3d_View class. 1) Exposing interface of OpenGl_View: The OpenGl_View inherits from new class Graphic3d_CView. Graphic3d_CView is an interface class that declares abstract methods for managing displayed structures, display properties and a base layer code that implements computation and management of HLR (or more broadly speaking view-depended) structures. In new implementation it takes place of eliminated Visual3d_View. As before the instance of Graphic3d_CView is still completely managed by V3d_View classes. It can be accessed through V3d_View interface but normally this should not be required as all its methods are completely wrapped. In more details, a concrete specialization of Graphic3d_CView is created and returned by graphical driver on request. Right after creation the views is directly used for setting rendering properties and adding graphical structures to be displayed. The rendering of graphics is possible after mapping a window and activating the view. The direct setting of properties makes obsolete usage of intermediate structures with display parameter like Visual3d_ContextView and etc (the whole package of Visual3d become redundant). 2) Collecting all high-level API methods of application views in V3d package: The patch includes elimination of Visual3d layer. All of its methods that could be previously used by application are now exposed and should be accessed on the level of V3d entities. - Introduced new class Graphic3d_CView. This is a base class for render views. Made possible to specialize concrete instances of the class by graphical driver. - Moved all methods managing rendering views into interface of Graphic3d_CView. The corresponding methods were removed from interface of graphical driver. 3) Eliminated Visual3d package: - Logic of managing display of structures was put from Visual3d_ViewManager into Graphic3d_StructureManager. - Removed Visual3d_View class. Logic of managing computed structures was put into base layer of Graphi3d_CView. - Removed all intermediate structures for storing view parameters e.g. Visual3d_ContextView. All settings are kept by instances of Graphic3d_CView - Removed Visual3d_Light intermediate class. All light properties are still stored in Graphic3d_CLight structure. The structure is directly access by instance of V3d_Light classes. - Moved all needed enumerations into Graphic3d package. 4) Update package D3DHost to new changes. 5) Update code of OCCT samples to new changes.
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).

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
