Matt Godbolt analyzes the source code and engineering tricks behind the 2D raycasting map renderer of Wolfenstein 3D.
Wolfenstein 3D was a triumph of early 90s engineering. It was an action packed 3d first person shooter - arguably the first - and it ran well on a 12 MHz 286 PC. How on earth was such a feat pulled off? Find out by watching this in-depth analysis of how the map renderer worked. Apologies for the small size of the graphics: this was an early video of mine and my later presentations look better! The Wolfenstein 3D source is available at: github.com/id-Software/wolf3d Source for this presentation: : github.com/mattgodbolt/wolf-doom-quakeWhy it's here

I found that the traditional route of OpenGL/ShaderToy/learnopengl/etc... was overwhelming as a newcomer to gfx.
I was finally able to break into graphics stuff after trying to implement a '2D' raycaster similar to the one in Wolfenstein3D. There are some Excellent videos on this raycaster.
If you don't want to get nitty gritty, interacting with Unity's shader system appears to be relatively painless (Especially in comparison to Unreal). There are also many Excellent videos exemplifying what you can do
