Selector noise is a third important noise generator used for terrain generation. This is effectively identical to low noise, but is only used when selector noise is above a given threshold value. This noise generator, which uses Perlin noise, is one which is actually used as a heightmap. Low noise is one of the two main noise generators used for defining terrain shape. Note that not all of these are used in vanilla, but are instead used by mods such as CubicWorldGen.įundamental terrain noise generators (Overworld) These are used for defining the shape of generated terrain itself.Ī table of default/hardcoded settings, as well as values resulting from these, is as follows. Stratum elevations vary with respect to the X-axis only, neglecting the Z-axis. The strata repeat every 64 blocks on the Y-axis, and the elevation of a particular stratum can vary through a biome by as much as 4 blocks. Stratum colors are determined using only the first 48 bits of the 64-bit world seed in Java Edition. Vanilla simply applies a "scale" value (frequency*(2^octaves)), defined as how much the noise generator increments per sampling (every four blocks). These values are displayed and calculated differently in the code. To shift the resulting set of values by this value. Offset: A value added to the noise after processing.To make the set of values more or less extreme. Factor: A value the noise is multiplied with after processing (lacunarity).More octaves added with lacunarity result in a rougher fractal appearance reminiscent of proper terrain. Fewer octaves result in an unnatural appearance. Octaves: The amount of different copies of this noise generator, each scaled down from the last by a factor of 2.Noise generators can be defined by the following parameters: 2.3.1 Major noise generation prior to Infdev 20100327.
