Member Function Documentation

__init__ ( )

Creates a StackedPerlinNoise3 object with no levels.

You should call add_level() to add each level by hand.

__init__ ( StackedPerlinNoise3 const copy )

Creates an exact duplicate of the existing StackedPerlinNoise3 object, including the random seed.

__init__	(	double	sx,
		double	sy,
		double	sz,
		int	num_levels,
		double	scale_factor,
		double	amp_scale,
		int	table_size,
		unsigned long int	seed
	)

Creates num_levels nested PerlinNoise3 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).

__init__	(	double	sx,
		double	sy,
		double	sz,
		int	num_levels,
		double	scale_factor,
		double	amp_scale,
		int	table_size
	)

Creates num_levels nested PerlinNoise3 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).

__init__	(	double	sx,
		double	sy,
		double	sz,
		int	num_levels,
		double	scale_factor,
		double	amp_scale
	)

Creates num_levels nested PerlinNoise3 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).

__init__	(	double	sx,
		double	sy,
		double	sz,
		int	num_levels,
		double	scale_factor
	)

Creates num_levels nested PerlinNoise3 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).

__init__	(	double	sx,
		double	sy,
		double	sz,
		int	num_levels
	)

Creates num_levels nested PerlinNoise3 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).

__init__	(	double	sx,
		double	sy,
		double	sz
	)

Creates num_levels nested PerlinNoise3 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).

addLevel	(	PerlinNoise3 const	level,
		double	amp
	)

Adds an arbitrary PerlinNoise3 object, and an associated amplitude, to the stack.

addLevel ( PerlinNoise3 const level )

Adds an arbitrary PerlinNoise3 object, and an associated amplitude, to the stack.

clear ( )

Removes all levels from the stack.

You must call add_level() again to restore them.
