Hacker News with Generative AI: Ray Tracing

Ray Tracing in One Weekend (raytracing.github.io)
I’ve taught many graphics classes over the years. Often I do them in ray tracing, because you are forced to write all the code, but you can still get cool images with no API. I decided to adapt my course notes into a how-to, to get you to a cool program as quickly as possible. It will not be a full-featured ray tracer, but it does have the indirect lighting which has made ray tracing a staple in movies.
Show HN: I've made a Monte-Carlo raytracer for glTF scenes in WebGPU (github.com/lisyarus)
This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API. It expects a single glTF scene as input. It supports flat-colored and textured materials with albedo, normal, and material maps. It doesn't support refraction (yet).

rtx-on.js is an experimental JavaScript library that enhances web pages by simulating in real time realistic lights and shadows using ray tracing.
