Ray Tracing in Nim

This is pretty good. I was wondering about CUDA and it looks like Nim has support for writing CUDA kernels. Is there a repository of kernel implementations I can take a look at?

https://github.com/mratsim/Arraymancer probably has a lot of examples in it's implementation

Yup. That's what popped up when I searched. Thanks for the reference though.

The CUDA kernels are stored here:

- https://github.com/mratsim/Arraymancer/blob/master/src/tenso...

With the higher order function:

- https://github.com/mratsim/Arraymancer/blob/master/src/tenso...

And their code generation:

- https://github.com/mratsim/Arraymancer/blob/master/src/tenso...

It's possible to avoid inlining C++ like they do here:

- https://github.com/jcosborn/cudanim/blob/338be782/cuda.nim#L...

but I will explore that later.
