Amazing #4

This is the best performance / quality ratio I've ever seen for a path tracer! Keep up the good work!

Hi @procedural , Thanks so much for the kind words! I can't really take credit for the various ray/path tracing techniques used in this project - some of them have been around since the 1980's. But I guess what I have a knack for is finding the right pieces/algorithms out in the wild and being able to fit them together and fine tune them to get what I want. :-)

My inspiration for this project is the incredible Brigade 1/2/3 path tracing engine now developed by OTOY. You can see videos of it in action all over YouTube. They are using multiple high-end GPUs and the latest NVIDIA ray tracing kernels (similar to my WebGL path tracing fragment shader, but much more optimized for CUDA tech), as well as BVH acceleration data structures. My hope is to one day be able to load large triangular meshes in my engine and have it run at 30 to 60 fps.

Thanks again for the encouragement. I'm currently looking into different BVHs to get towards what Brigade 1 and 2 could do (trying to find another piece of the puzzle to fit together - ha ha). Keep checking back! -Erich
