I've ran into a really interesting article today that I thought I'd share with you. It guides you through all the steps to implement a basic, but functioning ray tracer. I think it could be very useful/interesting for everyone to read.
Here's the article/guide: https://github.com/ssloy/tinyraytracer/wiki
It has the right amount of practical and theoretical content. It's pretty easy to follow, although it is still challenging and interesting to implement it in another language.
For reference, I have followed all the steps and implemented the ray tracer in LÖVE: https://github.com/Ulydev/loveray
Here's what you will end up with!
Have fun!
