>>> Recently I began adapting an unofficial Ray-Tracing extension for Dawn, which is the WebGPU implementation for Chromium

Wow, very impressive! I believe this is only available for MacOS Chrome Canary, with enable-unsafe-webgpu flags toggled on. But we are starting to see more example code.

This is the first specific RTX target engine I've seen so far though. Starting to feel like the future with full time real-time hardware rendering capabilities in the browser ;)

Do you mind my asking what you plan to build with it?
