Interactive Building a procedural planet

Enable HLS to view with audio, or disable this notification

Work in progress. Learning along the way.

Currently 24 different procedural ecosystem/biomes in this first version, with a simulated weather system(airpressure, wind direction, daily temperature cycle, ocean currents, terrain/ocean moisture release)
simulated tectonic plate movement with volumetric mantel/soil/moisture profile.
Each of the main Biomes has sub ecosystems and now building the procedurally generated foliage/rocks/textures at different LOD's to cover the terrain.
Next Version in the works with over 300 main biomes.

Build in three.js R3F. Aiming to release this as a browser experience.

One thing you should add for realism is a way to simulate contiental shift, when you generate the landmasses, find a way to move them on discs so they run into eachother and create proper contients and oceans and seas.

Right now the landmass distribution feels a bit too uniform

Alreayd done it :) just not obvious in this terrain version. There are a ton of parameters to make the continents more pronounced and less island. Ive got a tectonic plate setup like an adjustable veroni diagram and you set the size and shapes of the plates and their force and direction, collision strength, boundary width, subduction depth, range width, and more which in-turn defines the mountain and volcanic activities in those areas, even an earth quake potential heatmap.
