Rock 3

Rock 3 is a procedural world generator to build believable and interesting earth-like worlds. By modeling tectonics and climate it drastically simplifies the process of building detailed and realistic biomes across continents and islands, while providing the controls you need to fine-tune and customize near-infinite possible planets. Save your worlds as equirectangular projections of biomes, elevation, heightmap, heat, water, and landmasses.

Rock 3 generates planets entirely on your GPU. It’s not recommended to run this on a laptop or other device with integrated graphics. Your experience may also be compromised on an old or low-end graphics card. In some cases scaling the resolution of the planet down can improve performance to usable levels. Maps are always saved at the highest resolution.
