Hi folks,

Back to path tracers. In this one, I took a simple MonteCarlo brute force approach path tracer based on one example from shadertoy, and improve it in order to make it more efficient.

I added MIS (multiple importance sampling), ACESfilm tonemapping and gamma correction post frame accumluation.

If you’re interested, the original code is here:
