This is a very basic raytrace renderer written in Crystal for my talk "Computer Graphics for Ruby developers".
Please take into account that this project is not optimised in any way and only uses single process.
How to use
You can use already compiled binary
Or you can compile your own version:
shards install; crystal build src/crystal_tracer.cr --release;
Render output will be saved in
output.png within projects root direcrtory.
