Inigo Quilez live-codes the "Happy Jumping" animated scene in a Shadertoy GLSL shader over about six hours. He builds the raymarched character step by step, explaining the math and procedural techniques, with checkpoints linked for each stage.

Why Hacker News recommends it

HN commenters point to it as a patient, full-length walkthrough of how a raymarched shader is built from scratch.

“is fantastic, yes it's five hours but worth it.”

Indeed his videos are amazing . My recommendation though would be to start with the "beginner" video -- which is completely 2D but at least gets some ideas across. Then watch [link] which isn't his but introduces how you get 3D out of fragment shaders. Finally just drink from the firehose -- ▶ this video is fantastic, yes it's five hours but worth it. (Definitely come into that familiar with the idea of raymarching though... the first few minutes start off super basic but it goes to eleven real quick.)

If you have 6 hours to kill, check this shadertoy that uses ray marching: [link] And the video that goes through its creation step by step: ▶ this video
