Uses open simplex noise layered seven times on a 2D numpy heightmap, applies a circular gradient for an island, then carves mountain ranges by masking, offsetting, warping and multiplying with image noise; converts the heightmap to voxels and runs a hydraulic erosion simulation of 25,000 droplets (about 15 minutes per island on one CPU core) and extracts a mesh with marching cubes (psychic image implementation).
