I am creating a raytracer but it runs very slowly even though the code is very simple. I would like to know how to separate my code so that it will run more efficiently.
Hi, welcome to Snap!.
Do you know about the 
block? It does a lot of the hard part for you.
I forgot to mention that it is a 3d raytracer, however, if I make a 2d one that will be useful.
