TV and Movies have a ton of Computer Generated Images [CGI] to create fantasy worlds with dragons and castles, futuristic intergalactic civilizations, or historically accurate cities of 1700s Japan, such as in the recent TV show Shogun. But have you ever wondered how these CGI / Computer Generated Images are made? And how are these scenes so accurate that they fool the eye into thinking they are real. In this video, we're diving into Path Tracing, a type of Ray Tracing algorithm. We'll explore exactly how Ray Tracing is used to create accurate lighting and realistic scenes and how it uses quadrillions of calculations.
We're working on more ambitious subjects like computer architecture and graphics cards. Any contribution would greatly help make these videos.

First of all, credit goes to u/CorySama and u/Better_Pirate_7823 for most of this, I am mostly just copy-pasting from them.
If all goes well, we can Sticky this for everyone to see.

The main thing you need to know is https://fgiesen.wordpress.com/2016/02/05/smart/
OpenGL is a good API to start with. There's a lot to learn regardless of which API you use. Once you can do an animated character in a scene with lighting, shadows, particles and basic full-screen post processing, you'll know how to proceed forward on your own from there.
