Inigo Quilez codes a complete ray-marched mountain landscape in real time using mathematical equations and shaders on Shadertoy.

On “OP drew these corals with mathematical equations”
Indeed, Inigo Quilez is "the guy" for this kind of stuff. He co-created ShaderToy and has worked on effects and modeling for multiple Pixar films. My favorite video of his is Painting a Landscape with Maths. link to this video He deserves to have at least as many subscribers as other math YouTube channels like Verisatium and 3Blue1Brown.

Inigo Quilez, the author of this slide, also has made in-depth videos 1 2 which might be more accessible to who aren't familiar with shader languages. 1 link 2 link to this video

On “Source code for 4kb demoscene production “Elevated” released (2016)”
Thankfully for the graphics the very person who did the graphics in this Elevated demo is very generous with their time. Inigo Quilez has many instructional videos on his channel in how to code procedural graphics from the very beginner to the advanced. I link a couple of examples. You can watch the more advanced video even as a beginner but trying yourself is easier at the beginner level. Beginner. link Advanced. link to this video Website. link

On “Interactive Intro to Shaders”
Welcome to the Internet, superMayo! If you want to see what the Masters can do with shaders, let me introduce you to Inigo Quilez and his shader art: link to this video EDIT: I did not notice you are the author of this article. It's very well done, and I've been looking for more approachable and interactive tutorials on the arts of shader coding.

On “Programming terrain from scratch using C++ and OpenGL by Shamus Young (2006)”
I just finished watching a live-coding session (from 2 years ago) by Inigo Quilez (ex Pixar), where he constructs an entire ray-marched landscape using only maths (mostly SDFs) in pure GPU shader code. The stream: link to this video The demo: link

On “Genuary 2024: Generative Art / Creative Coding Month”
Edit: Hey my bad the prompts for Genuary are all for making visuals, but I suppose they could be interpreted for audio too. My bad, but I'll leave my music-nerd rant below in tact in case anyone finds it useful ---------------- This is awesome, I didn't know about this but I've been subconsciously preparing for it over Christmas break. Here's what I've found useful: Music: - Eli Fieldsteel's intro to SuperCollider course is fantastic. SuperCollider language is kind of nice. Function literals are simply curly braces, `{}`, and the last expression is returned. It has pipe's for function arguments, so if you squint it kind of feels like Ruby or Rust. // a silly function. Note that paren "blocks…
