Member Function Documentation

__init__

(

)

Randomizes the tables to make a unique noise function.

Uses a default scale (noise frequency), table size, and seed.

__init__

(

PerlinNoise2 const

copy

)

Makes an exact copy of the existing PerlinNoise object, including its random seed.

__init__	(	double	sx,
		double	sy,
		int	table_size,
		unsigned long int	seed
	)

Randomizes the tables to make a unique noise function.

If seed is nonzero, it is used to define the tables; if it is zero a random seed is generated.

__init__	(	double	sx,
		double	sy,
		int	table_size
	)

Randomizes the tables to make a unique noise function.

If seed is nonzero, it is used to define the tables; if it is zero a random seed is generated.

__init__	(	double	sx,
		double	sy
	)

Randomizes the tables to make a unique noise function.

If seed is nonzero, it is used to define the tables; if it is zero a random seed is generated.
