Generates a rectangular section of this generator's noise.

Parameters:

noise - the output of the previous noise layer

x - the X offset

y - the Y offset

z - the Z offset

sizeX - the size on the X axis

sizeY - the size on the Y axis

sizeZ - the size on the Z axis

scaleX - the X scale parameter

scaleY - the Y scale parameter

scaleZ - the Z scale parameter

amplitude - the amplitude parameter

Returns:

noise with this layer of noise added
