Method Details

sampleNoiseColumn

public void sampleNoiseColumn(double[] buffer,
 int x,
 int z,
 GenerationShapeConfig config,
 int seaLevel,
 int minY,
 int noiseSizeY)

Samples the noise for the given column and stores it in the buffer parameter.

getOffset

private double getOffset(int y,
 double depth,
 double scale,
 double randomDensityOffset)

Calculates an offset for the noise.

For example in the overworld, this makes lower y values solid while making higher y values air.

Interpolates the noise at the top and bottom of the world.

getDensityNoise

private double getDensityNoise(int x,
 int z)

Applies a random change to the density to subtly vary the height of the terrain.
