Drop Graphic3d_GraphicDriver::Begin() and ::End() methods.
Initialization is performed within driver constructor.
Drop dummy argument for Graphic3d_GraphicDriver constructor with library name.
Display connection now should be set instead
Drop Graphic3d::InitGraphicDriver() function and Graphic3d.hxx header.
Application code should explicitly link against TKOpenGl toolkit and instantiate OpenGl_GraphicDriver class.

Improve consistency and visual appearance of predefined OCCT materials in various rendering modes, including ray-tracing:
- Increase the specular exponents (shininesses) for metallic surfaces: Brass, Bronze, Copper, Gold, Pewter, Silver, Steel, Chrome, Aluminum.
- Revise specular colors for metals: Copper, Gold, Aluminum, Silver (according to "Real-Time Rendering, 3rd Edition", AK Peters 2008).
- Increase diffuse reflection of metals: Silver, Aluminum, Chrome (to make them brighter in OpenGL mode).
- Extend Material definition by Refraction Index.
Advanced rendering methods based on shaders or ray-tracing can utilize it to produce refraction effects.
In addition:
- Introduce three translucent materials: Water, Glass, and Diamond.
- Add Charcoal for modeling dark diffuse surfaces.
Add new TCL-based sample (materials.tcl) and test case (tests/v3d/materials/bug24855).
Install occt folder now can contain several occt configurations
- custom.bat/sh was added to include specific (for each occt config) custom.bat/sh files
- specific custom.bat/sh is added for each configuration (e.g., custom_vc9_win32_d.bat), generated by cmake and included within custom.bat/sh
- draw.bat has three argument, e.g., vc9 win32 debug (as occt behavior)
- sample.bat has one or four arguments, e.g., sample_name vc8 win64 release
- PATH is not changed. DRAWEXE.exe is called from specific folder
patched custom.[bat/sh].[main/in] files have higher priority than origin ones
Documentation was updated to describe new features of CMake
Seeking process of OpenCL include folder was fixed
Two scripts added:
samples/tcl/drill.tcl: creates model of a twist drill bit
samples/tcl/cutter.tcl: creates simplified model of a milling cutter
Added test cases bugs/modalg_5/bug24758_1 bug24758_2
New sample created for ray tracing in DRAW: samples/tcl/raytrace.tcl, rendering OCCT bottle with glass on a rectangular table, with shadows and reflections (if OpenCL is available). Sample bottle.tcl retains only modeling part.

- Fixed initialization of angle and length.
Corrections to support old results in geometry samples: added ISession_Direction::SetLineAspect(); ISession_Direction class in Modeling sample was corrected.
Some warnings were removed from MFC samples
All warnings of sample projects with warning level 4 were fixed on VC9
Warnings level increased to -W4 in projects of MFC samples; sample ReadMe files added to documentation
Changes in Viewer2dDoc.cpp and OcafDoc.cpp were restored.
Minor corrections in documentation
CMake meta-projects for samples were added
launch script for samples was added
unrelated changes: CSF_GraphicShr variable were removed
occt building with cmake article was updated
Some corrections; test cases were added; coding standards in MFC samples & presentations
Request stencil buffer for Linux.
correct test cases; correct compilation errors
compilation warnings (gcc/Linux)
The purpose of this functionality is to bring a basic ray-tracing solution to existing OCCT visualization toolkit (TKOpenGL).
Currently ray-tracing visualization core supports sharp shadows, specular reflections, transparency and adaptive anti-aliasing.
However, the basis for all ray-tracing algorithms is versatile, allowing you to add new ray-tracing features easily (such as ambient occlusion).
All ray-tracing computations are performed on the GPU using OpenCL framework, allowing real-time rendering performance.
It is important to note, that real-time ray-tracing is possible using high-performance GPUs with support of OpenCL 1.1 and higher (such as NVIDIA GeForce 660 or ATI/AMD Radeon 7850).
When using low-end GPUs (such as NVIDIA GeForce 640) the ray-tracing performance may slow down significantly.
Therefore, even with NVIDIA GeForce 640 you can render scenes with the millions of triangles. The support of OpenCL-enabled CPUs and integrated graphics cards is not guaranteed.
Overall revision of of CSharp sample code:
- Pure C++ project "OCC" deleted as unnecessary
- C++/CLI project "shell" renamed to OCCTProxy and refactored to implement all required interface to OCCT functionality.
- In About dialog, date corrected in Copyright statement
- CSharp files re-layouted with 2 spaces indentation
- ReadMe converted to MarkDown format and revised
- Generation of names of views refactored to avoid calling C++ level
- Project files corrected to run on 64-bit systems
- Batch scripts refactored to use OCCT default configuration
WPF front-end added to demonstrate usage of OCCT in WPF applications.
WPF sample was modified, operation Export has been fixed
Exception "Cannot create this file", which appeared by export to image format, has been corrected.
Option "Export image to .xwd" removed.
