Procedural art is fascinating and worthy of a deep dive too since it combines art, modelling, rendering, programming and maths (constraint solvers, discrete optimization, more).
Anastasia Opara (“procedural art nerd”) has a Gumroad with procedural art tutorials that show how to create environments procedurally with Houdini: https://anopara.gumroad.com/ (the first one is free)
Tomasz Stachowiak (“technical debt generator”) gave a talk at GPC 2024 earlier this month called “rendering tiny glades with entirely too much ray marching” (no recording I can find yet but worth keeping an eye on): https://www.graphicsprogrammingconference.nl/#tiny-glade
Outside of the Tiny Glade team, Oskar Stålberg (Townscaper) is worth following for his frequent insights into proc-gen: https://x.com/OskSta
