OpenCL GPGPU Complex Raytracing - BRL-CAD

    https://brlcad.org/wiki/OpenCL_GPGPU_Complex_Raytracing
    With implicit geometry and constructive solid geometry (CSG) Boolean operations, we also have a very different approach to ray tracing that has its own set of academic challenges. Your project is to help us introduce a GPGPU pipeline into BRL-CAD using OpenCL. You're welcome to use a library that encapsulates OpenCL.

gpgpu - Raytracing in OpenGL via compute shader - Stack …

    https://stackoverflow.com/questions/15344282/raytracing-in-opengl-via-compute-shader
    As you can see in the GPU rendered image there is a red pixel in the middle which is caused by the last lines in the compute shader. This can be reproduced for every other pixel. I use a resolution of 1024x768 at the moment and this is how I dispatch my compute shader: #define WORK_GROUP_SIZE 16 void OpenGLRaytracer::renderScene (int width, int ...

Ray traced rendering using GPGPU devices

    A ray tracer on current graphics hardware reaches the speed of a good CPU implementation already. Combined with classic triangle based real time rendering, the GPU based ray tracing algorithm could already be used today for certain special effects in computer games. 2 Contents 1.
