Detailed Description

a class that implements the Bridson fast sampling algorithm, in a periodic domain

Robert Bridson, "Fast Poisson Disk Sampling in Arbitrary Dimensions" SIGGRAPH sketches (2007)

Constructor & Destructor Documentation

poissonDiskSampling()

poissonDiskSampling::poissonDiskSampling	(	int	pts,
		scalar	radius,
		vector< dVec > &	sample,
		noiseSource &	noise,
		shared_ptr< periodicBoundaryConditions > &	Box,
		int	max_sample_attempts = 30
	)

the consructor also does all of the work
