Method Detail

NOISE

public double NOISE(double x,
                    double y)

2D combined (multi-frequency) Perlin noise function.

Parameters:

x - Interpolation position x.

y - Interpolation position y.

Returns:

The value of the combined Perlin noise function for the two-dimensional position (x,y).

noise

public double noise(double x,
                    double y)

2D elementary (single-frequency) Perlin noise function.

Parameters:

x - Interpolation position x.

y - Interpolation position y.

Returns:

The value of the elementary Perlin noise function for the two-dimensional position (x,y).
