Neat. I’ve been looking for something like this for gamedev — being able to model pseudo-realistic simulation of planetary evolution (for my interest, just starting at plate tectonics and going up until wind patterns) to provide a “basis” for further simulation.

It’s surprisingly hard to google though; almost all content is simple perlin noise generation that looks kind of correct but ultimately produces total nonsense (so any further derived rules have to also be total nonsense) — generally constrained with further nonsense rules to produce higher level concepts like “animals” and “biomes” that can’t be touched meaningfully.

Other material I can find is far too involved, and far too slow — targeting actual simulation of the earth. The few that do it with the goal of “just realistic enough” still end up being 10+ minutes generation time for small worlds. Modeling erosion processes being the main culprit, afaict.

Definitely stealing this one, for all my nefarious deeds.
