I’m going to have to read this comment many times, but this part is totally confusing to me:

> You can then cast rays through 3D space mapped onto 1D space, with one ray per GPU thread.

I can’t figure out what this actually means, to map a 3D space onto a 1D space?

The Wikipedia page has a concise explanation for this particular sort of locality-preserving mapping: https://en.wikipedia.org/wiki/Z-order_curve

It also gives a potentially better alternative.
