Hi!
I started developing a real-time path tracer with SFML + raw OpenGL, and would like to share my results so far.
These renders are full of visual artifacts caused by bugs in the tracer, but as soon as I iron out those bugs I will upload an executable as well as the source code

All the ray tracing is done in a GLSL shader, and the scene is uploaded as a set of texture buffers containing the spatial partitioning tree and the geometry/material data.
It loads .obj models, and has multi-bounce global illumination.
