To echo this sort of experience, I recently bought the pragprog book The Raytracer Challenge, and it was similarly satisfying. I wasn’t really out to follow OP’s advice to “get into” graphics, but I saw the book release and wanted to give it a shot. To be able to see a 3D-rendered sphere appear on screen using code that I wrote from the very bottom up is deeply, deeply satisfying (and a great way to level up with the programming language of your choice).
