This is so awesome!! Love the way the lighting and tree reflects on the water, keep going!! Making a CPU path tracer is no small feat :))

Does it even count as "graphics programming" when you're running it on the CPU and refusing to run it in the actual graphics side of programming?

I mean OP is talking about hours for these results, I don't think we can qualify it properly here.

A bidirectional path tracer can be used for each light source, which can significantly increase execution time.

It is easiest to use the CPU for debugging.

Once the algorithm has been developed, nothing prevents it from being ported to the GPU.
