sampleBeta

public final double[] sampleBeta(double x,
                                 double y,
                                 double z,

                                 double scaleZ)

Beta 3D noise sampler. This creates a flattened 3D array and samples all values at once.

Parameters:

x - Initial x-coordinate

y - Initial y-coordinate

z - Initial z-coordinate

sizeX - Length along x-axis

sizeY - Length along y-axis

sizeZ - Length along z-axis

scaleX - x-coordinate scale

scaleY - y-coordinate scale

scaleZ - z-cooridnate scale

Returns:

An array of noise values from the starting coordinates to end coordinates specified by the dimensions.

sampleAlpha

public final double[] sampleAlpha(double x,
                                  double y,
                                  double z,
                                  int sizeX,
                                  int sizeY,
                                  int sizeZ,
                                  double scaleX,
                                  double scaleY,
                                  double scaleZ)
