How do you make textures for games WITHOUT drawing them?
you may want to start with (4d cellular) ashima-simplex-noise functions of https://github.com/ashima/webgl-noise as basis function, as this is not convergent+iterative like other procgen functions (that are more like a convergent game-of-life). demos of them are in https://www.shadertoy.com/results?query=ashima&sort=newest&filter=

Best noise algo for height-mapping continents on a sphere?
Oh nice. I think the GLM noise is actually based off the Ashima Arts + Stefan Gustavson GLSL noise https://github.com/ashima/webgl-noise
- Simplex noise(or any fast smooth noise functions) in godot shaders?

Added 3D Noise and Blend Modes to my GLSL Noise library (gl-Noise)! Used it to make a Planet Generator. Demo and GitHub in comments!
Oh I see what you mean now. Not saying https://github.com/KdotJPG/OpenSimplex2 isn't safe, just that https://github.com/ashima/webgl-noise/blob/master/src/noise3D.glsl isn't. Ty for clarifying, makes perfect sense now!

Biome generation using 7 noise maps. Some generation patterns don't quite make proper sense, but I'm happy with it!
Several years ago when I was experimenting with all of this I found that OpenSimplex was significantly slower than regular Simplex (not sure what library I was using). Maybe it's improved since then? Anyway, I've since moved my noise computation to the GPU and speed is less of an issue for that particular project. I'm currently using the simplex noise function from GLM, which comes from https://github.com/ashima/webgl-noise. Do you have any idea how that compares with the various noise functions you've listed?

I finally nailed the smooth rotation of a noise field. No unsteady or flickering edges anymore. No quality loss no matter what the actual rotation angle is.
Wow you have been playing with noise for a while :) . It amazes me all the different noises that exist now.. Perlin, Simplex, OpenSimplex, OpenSimplex2S, OpenSimplex2F, Worley... If you are curious about OpenSimplex https://github.com/KdotJPG/OpenSimplex2

Some of the results of my work-in-progress tool to generate random tile-based worlds. (More info in comments)
Probably true, although a neat repo for open simplex is https://github.com/KdotJPG/OpenSimplex2

Value Noise Resources
This may not answer what you're actually looking for - but a few years ago I found a library for coherent noise in Java, which at least meets my needs. I use bits and pieces of the Open Simplex Noise implementation from that library. It's unlicense/CC0, so easily copy-paste-able straight in to one's own project. https://github.com/KdotJPG/OpenSimplex2/

Question about OpenSimplex2S
So I was looking for a noise function, and I found this repo from the author of the OpenSimplex algorithm. And in the GLSL implementation, which is the one I'm gonna use, since I want to generate terrain with compute shaders, the function%20%7B) looks like this:

How would you loop a 3D noise?
If you want to feel safer from that, you might opt to use one of these instead. Use the ImproveXY endpoint to get a Z that repeats after 500.5626833874055. Go up one directory and into the glsl directory if you need GLSL versions instead .

Map + River generation using the "Lanczos Value-Noise" I wrote [Details in the comments]
Fair. I definitely agree Simplex has some characteristics that don't work great in some places. Especially when you threshold near zero of a single octave. Have you tried OpenSimplex2S? It's made to be less "bubbly" than standard simplex. In own repo, In FastNoiseLite, [Shader preview (3D noise)[https://www.shadertoy.com/view/ttdGR8]. Both the 2D function and 2D slices of the 3D function might be worth looking into if you haven't yet.

Need some help making the GLSL implementation of OpenSimplex2 tileable
Here's a link to the original implementation: github.com/KdotJPG/OpenSimplex2/blob/master/glsl/OpenSimplex2.glsl
- Oh cool, i just found this sub reddit and had a few questions on my current project.
What are some alternatives?
When comparing webgl-noise and OpenSimplex2 you can also consider the following projects:
FastNoise - Fast Portable Noise Library - C# C++ C Java HLSL GLSL JavaScript Rust Go
3DWorld - 3D Procedural Game Engine Using OpenGL
FastNoise2 - Modular node graph based noise generation library using SIMD, C++17 and templates
glNoise - A collection of GLSL noise functions for use with WebGL with an easy to use API.
Noise-Extras - Noise & procedural generation code pieces that I didn't feel needed whole repos all to themselves.
simplex - Simplex noise implementation offering 1D, 2D, and 3D forms.
