user sees just dirs of libs, shared libs and headers of 3rdparty products
documentation updated
3rdparty search priority was fixed: 1. user paths; 2. system paths
3rdparty debug usage fixed
vtk search introduced
occt information, generated by wok, was divided onto two files: occt_toolkits.cmake and occt_inc_toolkits.cmake
additional behavior of cmake search for freetype 2.5.1 and above
CMake (version < 3.0) don't know about new place of config/ftheader.h in freetype 2.5.1. There are cases when cmake seeks config/ftheader.h in defined place (3RDPARTY_FREETYPE_DIR variable), doesn't find it and start new search in system places. If system has own freetype header- cmake will find it and 3RDPARTY_FREETYPE* variables will point to different places. This situation is avoided
tcl, freetype, vtk are checked before usage of it (CSF variables usage)
tbb search mechanism was refactored
freetype search is processed by default cmake mechanism
tcl search is processed by default cmake mechanism
3rdparty macro seeks debug libraries (and release if debug ones aren't found); 3rdparty dll is sought in win case only
ADD_SUBDIRECTORY preferred to SUBDIRS
gendoc.bat search for tclsh.exe in user's system
0025141: CMake / MinGW: link recipe fails due to long command

0023422: Selection problems when using SetLocation.
0024756: AIS_ConnectedInteractive does not support nested AIS_ConnectedInteractive
0025103: Visualization - Regression in interactive detection
Each PrsMgr_PresentableObject has list of PrsMgr _PresentableObject called myChildren.
Transformation PrsMgr_PresentableObject applied to its children every time when its own transformation affected. This hierarchy does not propagate to Graphic3d level and below.
PrsMgr_PresentableObject send its combined (according to hierarchy) transform down to Graphic3d_Structure.
AIS_ConnectedInteractive and AIS_MultiplyConnectedInteractive are reused but behavior has been changed.
AIS_ConnectedInteractive now is an instance of object. It reuses geometry of connected object but have own transformation, material, visibility flag etc. This connection propagated down to OpenGl level to OpenGl_Structure. For this task old “connected” mechanism has been reused.
AIS_MultiplyConnectedInteractive represents assembly which doesn’t have its own presentation. Assemblies are able to participate is scene hierarchy and intended to handle a grouped set of instanced objects. It behaves as single object in terms of selection. It applies high level transform to all sub-elements since it located above in the hierarchy.
All AIS_MultiplyConnectedInteractive are able to have child assemblies. Deep copy of object instances performed when one assembly attached to another.

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.

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.
