From now on, the panning behavior of V3d_View completely corresponds to equal operations with camera. There is no more confusing "Center" property and "ProjectionShift" which were used to introduce composite panning, while respecting view referential points: At, Eye unchanged. The V3d_View::FitAll approach has been rewritten to do "fit all" geometrically, operating with frustum, to make it working for both orthographic and perspective projections.
1) Getting rid of ProjectionShift and Center property:
- Removed ProjectionShift property of Graphic3d_Camera.
- Removed confusing Center property of V3d_View (related to projection shift).
- Removed redundant code related to the Center property of V3d_View.
- Removed WindowLimit method of Graphic3d_Camera - no more used.
2) Improvements of fit all and selector:
- Improved FitAll operation of V3d_View and reused it in NIS_View - the perspective projection is now handled correctly.
- Revised code of Select3D_Projector class - can be defined with any given projection and model-view matrices.
- Modified StdSelect_ViewerSelector3d and ensured that panning, zooming and going into the view do not lead to unwanted re-projection of sensitives. The handling of perspective selection is revised.
- Take into account graphical boundaries of infinite structure on ZFitAll.
3) Improvements of camera:
- Introduced new z range scale parameter for V3d_View::AutoZFit. See, V3d_View::AutoZFitMode.
- Allow negative ZNear, ZFar for orthographic camera to avoid clipping of viewed model.
- Moved camera ZNear, ZFar validity checks to V3d_View level.
- Use more meaningful Standard_ShortReal relative precision for ZNear, ZFar ranges computed by ZFitAll.
- Use Standard_Real type for camera projection and orientation matrices.
- Extended camera to generate both Standard_Real and Standard_ShortReal transformation matrices using the same matrix evaluation methods and converted input parameters.

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.
