I am curious as well. Unfortunately there's not a lot of info out there. It's a bit weird to me that the repo says it's a CPU renderer, but most of the code seems to use the GPU (with rust-wgpu).

With so little documentation it's hard to know exactly how it works, but I am curious if its architecture is similar to: https://raphlinus.github.io/rust/graphics/gpu/2020/06/13/fas...
