All Implemented Interfaces:

Function3D

public class VoroniFunction3D
extends Object
implements Function3D

Function that produces a Voronoi graph by placing a random point in every 1x1x1 unit cube in space and then finding the closest of these points at each eval location.

Constructor Details

VoroniFunction3D

public VoroniFunction3D()

Construct with default values.

VoroniFunction3D

public VoroniFunction3D(double frequency,
 double displacement,
 boolean useDistance,
 int seed)

Construct a new Voronoi graph function.

Parameters:

frequency - used to modulate input coordinates

displacement - use to modulate the contribution of the random points in each unit cube.

useDistance - if true, we will add the distance from the closest point to our output, giving us variation across the cell.

seed - the random seed value to give to our integer random function.

Method Details

eval

public double eval(double x,
 double y,
 double z)

Specified by:

eval in interface Function3D

Parameters:

x - the 1st value in our tuple

y - the 2nd value in our tuple

z - the 3rd value in our tuple

Returns:

some value, generally (but not necessarily) in [-1, 1]
