0024130: Implementing ray tracing visualization core
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.

The Build (Assembly) Part of BO consists of several sub-parts:
1. Building Vertices
2. Building Edges
3. Building Faces
4. Building Solids
5. Building Container Shapes (Wires, Shells, Compsolids, Compounds)
Among the parts above
3.Building Faces
and
4.Building Solids
are the most time-consuming and thus should be parallelized first.
The parallelization process can be divided on three phases:
1. Parallelization Building Faces
2. Parallelization Building Solids
3. Parallelization the rest parts
The phase 1 : Parallelization Building Faces consists of three parts:
1.1. Building Split Faces
1.2. Building Same Domain Faces

1. To avoid creation of micro edges in the class BOPAlgo_PaveFiller added two new functions ForceInterfVE and

2. In the class BOPInt_Tools added new function IsInRange which checks whether two ranges cross each other.
3. In the class BOPTools_AlgoTools added new function IntersectCurves2d which intersects pcurves of the face
to check it on the self-interference.
4. In the function IntTools_BeanFaceIntersector::FastComputeExactIntersection() the check on the coincidence of the whole
edge with the face (BOPTools_AlgoTools::IsBlockInOnFace) replaced with the check on the coincidence of one intermediate point with that face.
5. Test cases bugs modalg_1 bug1255, bug1255_1 has been updated with more correct value of the result.
6. TODO statement has been removed from the test cases boolean bcut_complex B1,B3,B5,C2,C4,C6,C8 as they are correct.

Modification 2
1. In class BOPAlgo_PaveFiller added new function CheckPlanes(nF1, nF2) that checks whether two planar faces have common or intersecting sub shapes.
If these two faces do not have such sub shapes there is no need to intersect them.
2. In the function BOPAlgo_PaveFiller::MakeBlocks() added block for reducing the tolerance values to the previous state for the vertices
