Method Detail

noise

public static float noise(float x,
                          float y)

Compute 2D simplex noise for the given input vector (x, y).

The result is in the range [-1..+1].

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

the noise value (within [-1..+1])

noise

public static float noise(float x,
                          float y,
                          float z)

Compute 3D simplex noise for the given input vector (x, y, z).

The result is in the range [-1..+1].

Parameters:

x - the x coordinate

y - the y coordinate

z - the z coordinate

Returns:

the noise value (within [-1..+1])

noise
