Wind direction from noise map?

  22 23 4.4 Java

  Noise & procedural generation code pieces that I didn't feel needed whole repos all to themselves.

Either way /u/pds314 I would look for a good simplex-type noise impl that supports derivatives. Here's one. Alternatively, here's a domain-rotated Perlin which addresses its square artifacts by rotating them out of the evaluation plane of focus through the extra dimension. In this, use X and Y of the 3D "ImproveXY" function" or X and Z of the 3D "ImproveXZ" function for derivatives. In the OpenSimplex2S, you can just use the 2D function with derivatives.

  This program procedurally generates gas giant cubemap textures for the game Space Nerds In Space. https://www.patreon.com/smcameron

It's the core idea underlying gaseous-giganticus -- here's some output. Here's a bunch of pics of various scales of noise field. Curly Vortex is a Processing program that does the same thing in 2D to an image... some sample output here.
