StackedPerlinNoise2¶

class StackedPerlinNoise2¶

Implements a multi-layer PerlinNoise, with one or more high-frequency noise functions added to a lower-frequency base noise function.

StackedPerlinNoise2.__call__()¶

StackedPerlinNoise2.__init__()¶

Creates a StackedPerlinNoise2 object with no levels. You should call add_level() to add each level by hand.

Creates num_levels nested PerlinNoise2 objects. Each stacked Perlin object will have a scale of 1 scale_factor times the previous object (so that it is higher-frequency, if scale_factor > 1), and an amplitude of amp_scale times the previous object (so that it is less important, if amp_scale < 1).

Creates an exact duplicate of the existing StackedPerlinNoise2 object, including the random seed.

StackedPerlinNoise2.add_level()¶: Adds an arbitrary PerlinNoise2 object, and an associated amplitude, to the stack.

StackedPerlinNoise2.assign()¶

StackedPerlinNoise2.clear()¶: Removes all levels from the stack. You must call add_level() again to restore them.

StackedPerlinNoise2.noise()¶

Returns the noise function of the three inputs.
