Realtime Pathtracer Research

"Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality."
from wikipedia

For a long time I've wanted to learn more about pathtracers. I finally got around to it a few months ago and the result of my investigation was a fork of Evan Wallace's Pathtracer with a few new features and shapes - some of which I learned from Erich Loftis’s Three.js PathTracing Renderer

Another Demo...

Been wanting to get back to this and do optimizations and boolean shapes - but so far I haven't gotten around to it.

Here are a few more screenshots from various permutations and experiments...

Working on this stuff brought back memories of waiting 15 hours for KPT Bryce to render 3D landscapes...

still have a copy running on my 2018 macbook pro ;)

This is awesome. I think Ray tracing is quiet useful in 3D world to achieve more levels of realism. Having this on the web is a great step forward.

Fun timing. I wouldn’t have had any idea otherwise.
