API reference / @jsprismarine/worldgen / SmearedPerlinNoise

Class: SmearedPerlinNoise

Defined in: noise/SmearedPerlinNoise.ts:15

Perlin noise whose y fraction is snapped down to a multiple of fudgeYScale before the lattice lookup while the interpolation weight stays on the unsnapped fraction.

This is the "smearing" that gives Java Edition's old blended noise its vertically stretched cave shapes. Only the blended noise builder builds these.
