CPU support #5

It should be possible to port the rasterizer to CPU (maybe via HIP), or simply rewriting it.

It might be slow, but it would give people the freedom to run this stuff without the NVIDIA tax.

yes please!

pierotofy commented 8 months ago

Work in progress!

Forward and backward rasterization passes working.

Workss! (200 iters on low resolution).

About 100x slower than GPU, but it's a start.

Wow

500 iters and still going strong! I will open a PR.
