Procedural Generation

Noise Functions

Classic Perlin noise with gradient interpolation. Explore FBM octaves, persistence, and multiple color modes.

Improved noise algorithm with less directional artifacts. Side-by-side comparison with Perlin noise.

Cellular/Voronoi noise with animated feature points. Multiple distance functions: F1, F2, F2-F1.

Fractal Brownian Motion for realistic clouds. Presets for cumulus, stratus, cirrus, storm, and sunset.

Four generation methods: BSP trees, random rooms, cellular automata, and drunkard's walk.

Cellular automata caves with configurable rules. Flood fill for regions and automatic connection.

Noise-based heightmap rendered as 3D mesh. Biome coloring: water, sand, grass, rock, and snow.

Spherical planets with 3D noise terrain. Planet types: Earth-like, desert, ocean, ice, volcanic.

Isometric procedural cities with varied building heights. Day/night mode with lit windows.

Space colonization algorithm for natural trees. Types: oak, pine, willow, and cherry blossom.

Hydraulic erosion simulation. Water flows downhill, carving valleys and depositing sediment.

Chunked streaming terrain for endless worlds. Fly through procedurally generated landscapes.
