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.
Project file extension corrected for VS 2010/2012 solutions
Sources and resource files from Common and Interface sub-foldrs added to qmake project files from their original location.
RES_DIR environment variable redirected to the binary directory, all resource files copied there to keep the source tree intact.
RES_DIR environment variable corrected under Linux/MacOS similalry to Windows.
Makefile generation corrected under MacOS:
- filenames used as the output for the extra compilers instead of the absolute paths.
- mkdir and cp command options corrected
