Class PoissonDistribution

micycle.pgs.commons.PoissonDistribution

@Deprecated
public final class PoissonDistribution
extends Object

Deprecated.

in favour of PoissonDistributionJRUS

Generates sets of random points via Poisson Disk Sampling. Poisson-disc sampling produces points that are tightly-packed, but no closer to each other than a specified minimum distance, resulting in a more natural and desirable pattern for many applications. This distribution is also described as blue noise.

Implements Martin Roberts’s tweak of "Fast Poisson Disk Sampling in Arbitrary Dimensions" by Robert Bridson.

generate

public List<processing.core.PVector> generate(double xmin,
 double ymin,
 double xmax,
 double ymax,
 double minDist,
 int rejectionLimit)

Deprecated.

Generates a random point set, having a poisson/blue noise distribution.

Parameters:

xmin - x-coordinate of boundary minimum

ymin - y-coordinate of boundary minimum

xmax - x-coordinate of boundary maximum

ymax - y-coordinate of boundary maximum

minDist - minimum euclidean distance between any two points

rejectionLimit - the limit on the number of attempts to generate a random valid point around the previous point. Generally 6 is sufficient.

Returns:

a set of random points
