Real-time Path Tracer

[lolz123]

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.



A version with more samples:

sweet. i once upon a time wrote a raytracer in lisp, fun stuff!

Here is a picture from a newer version, which refines the image over time. I will release the source code as soon as I figure out why it won't run in release mode!

Here it is rendering the Sponza at a whopping 1 frame / second

And this is how a simple test level looks when everything is a mirror (4 bounces, 3 fps)

This looks great!
Need to make one of my own once I have some free time.
