Penumbra is a
Ray Tracer Challenge
implementation built for the web. It’s a work in progress.

Finally! Ray casting! Plus an interactive demo of a sphere’s shadow.
An overdue and long update covering 3 chapters! The site has moved to its permanent home and the demo for these chapters is a neat little animated clock.
An interactive web component already!
Just one more yak to shave before I can get started on the first test.
I just want to start this challenge, but there’s a bunch of things I need to figure out first.
