Detailed Description

This class provides an implementation of Perlin noise for 3 variables.

This code is loosely based on the reference implementation at http://mrl.nyu.edu/~perlin/noise/ .

Constructor & Destructor Documentation

◆ PerlinNoise3() [1/3]

PerlinNoise3::PerlinNoise3 ( )

inline

Randomizes the tables to make a unique noise function.

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

Definition at line 19 of file perlinNoise3.I.

◆ PerlinNoise3() [2/3]

PerlinNoise3::PerlinNoise3	(	double	sx,
		double	sy,
		double	sz,
		int	table_size = `256`,
		unsigned long	seed = `0`
	)

inlineexplicit

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.

Definition at line 33 of file perlinNoise3.I.

References set_scale().

◆ PerlinNoise3() [3/3]

PerlinNoise3::PerlinNoise3 ( const PerlinNoise3 & copy )

inline

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