For some context, I think this is by mr.doob of three.js fame.

I have fond memories of visiting a university in the early 90s on a demo day and there was a (physical) sphere in a Cornell box:

And next to it was a super beefy computer doing a 3D rendering of a similar scene.

35 years+ later I've got "many spheres in a Cornell box" rendering in my browser, love it : )

Fun simulation. The novelty of stuff like this still hasn't worn off for me in this era where we've got ray tracing in-browser.

Beware: this might totally freeze your computer like it did for me.

This runs pretty smoothly on my middling laptop CPU while looking like a typical raytracing demo. I assume there's some smoke and mirrors involved?

I was able to get all the balls stuck on the 'ceiling'. Bug or feature?

Beautiful, this must have been an excellent learning experience to make.

I've done some very basic rendering code in C from a rendering internals course, and at the same time I'm learning about perspective from the drawing/art side. I wonder how much learning one would help the other, in a practical way.

I'm a C++ programmer and only passingly familiar with web/JS stuff. What libraries/technologies is this using, apart from Javascript and three.js?

path tracer?

Is this marketing for the Shape Store? It's cool but I still don't know when my area is getting a Shape Store.
