* some initial cuda code as I learn. using git to save progress. * first cuda kernel for ray sampling that mostly works * cleaning up code. working on lr. structs for scene bounds aabb * added scene bounds collider code * updated setup * setup * setup * black * including some files * exporting env variable * new file * git workflows * github actions * github actions * github actions * removing env var
