Heightmap terrain from fractal noise
In your harnessMesh algorithmMIT
Generate a square terrain mesh from seeded fractal gradient noise, with central-difference normals, UVs and colours banded by height and slope. Use it for game ground, backdrops and test terrain.
What it takes and gives
- Entry points
- height_at, terrain_color, heightmap_terrain, main
- Parameters
- size, resolution, height, feature_size, octaves, seed
- Complexity
- O(resolution^2 * octaves)
- Axes
- +Y up, metres
Limits. A single height per (x, z): no overhangs, caves or arches. The noise is not periodic, so tiles do not wrap. Heights stay within about plus or minus the height parameter (at most twice it). The colour bands are a fixed stylized palette, not a physical material model.
