Graphic3d_AspectFillArea3d has been extended by new property ::ShadingModel(), which is set to Graphic3d_TOSM_DEFAULT by default. The new API allows assigning Shading Model to specific Primitive Array groups instead of entire Viewer, which was the only possibility before. Graphic3d_TypeOfShadingModel has been extended with Graphic3d_TOSM_DEFAULT value meaining that Shading Model defined as default for the Viewer should be used. Graphic3d_TOSM_NONE has been renamed to Graphic3d_TOSM_UNLIT. Documentation of Shading Models has been improved by more details. V3d_TypeOfShadingModel enumeration has been merged into Graphic3d_TypeOfShadingModel avoiding duplicated definitions and confusion. Old values has been left for compatibility with old code and can be marked deprecated in future. Draw Harness command vaspects has been extended by new argument -setShadingModel for testing Shading Models assigned to entire objects. OpenGl_SetOfShaderPrograms now holds an array of Shading Models. OpenGl_ShaderManager interface has been modified and now requires enumeration as input in several places where Boolean flags have been used previously (methods ::BindFaceProgram(), ::BindLineProgram(), ::BindMarkerProgram()). OpenGl_Workspace now defines default (undefined) OpenGl_AspectFace as Graphic3d_TOSM_UNLIT to simplify indication of primitive groups with undefined Fill Area aspects, and so that Graphic3d_TOSM_UNLIT set as default Shading Model will not make artifacts on Lines and Markers. AIS_Manipulator::Axis::Compute() - added missing initialization of Fill Area aspects (leading to undefined behavior).
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 C++ header and source files of OCCT, documentation sources, build scripts, and CMake project files. - Complete source archive: contains all sources of OCCT, generated HTML and PDF documentation, and ready-to-use projects 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.com 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 accompanying 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). Use batch file *gendoc.bat* on Windows or Bash script *gendoc* on Linux or 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
