PerlinNoise

A perlin noise generator. Can be created either via PerlinNoise(seed, octaves, persistence, scale) or minetest.get_perlin(seeddiff, octaves, persistence, scale). Note that PerlinNoiseMap works faster.

Methods

• get2d(pos) — 2d noise value at pos={x=,y=}
• get3d(pos) — 3d noise value at pos={x=,y=,z=}

Examples

See VoxelManip example
