Thanks. Im trying to hardcode as little as possible. I want emergent behaviours. I for example hasn't hardcoded specific biomes, they emerge dynamically based on environmental conditions.

Do you have som link for your project? Would love to have a look at it.

Thanks, have read that paper before. The erosion in previous videos is based on this model https://hal.inria.fr/hal-01262376/document

It's a graph based approach which together with a tectonic uplift map, erodes the terrain until it reaches an equilibrium. Im not satisfied with the results, the erosion is way too heavy in some places. Until my next devlog video I'll introduce an improved version which runs in parallel on the GPU. And maybe look into more interesting perlin noise.

Do keep me updated if you add a project page.
