A real-time raytracer written in C, using OpenCL and SDL2. Tested to run only on MacOS. Untested on other platforms.
This is a collaboration of 4 people. Henrik Caspar, Florian Declerck, Théophile Trosseau, and me.
I was responsible for the rendering pipeline and GPU operations. You will find my work in the GPU Kernel, and in the OpenCL and GPU data transfer operations functions.
You can read "RT - Pipeline presentation" to get a condensed overview of the thinking behind the rendering pipeline design.
