Constructor Details

SpiralSampling
public SpiralSampling(long seed) Create a new instance ofSpiralSampling
and initialize the random number generator with the givenseed
. Parameters:
seed
 the seed to initialize the random number generator with


Method Details

createEquiAngle
CreatenumSamples
number of samples on a spiral with maximum radiusradius
around the center usingnumRotations
number of rotations along the spiral, and call the givencallback
for each sample generated.The generated sample points are distributed with equal angle differences around the spiral, so they concentrate towards the center.
 Parameters:
radius
 the maximum radius of the spiralnumRotations
 the number of rotations of the spiralnumSamples
 the number of samples to generatecallback
 will be called for each sample generated

createEquiAngle
public void createEquiAngle(float radius, int numRotations, int numSamples, float jitter, Callback2d callback) CreatenumSamples
number of samples on a spiral with maximum radiusradius
around the center usingnumRotations
number of rotations along the spiral, and call the givencallback
for each sample generated.The generated sample points are distributed with equal angle differences around the spiral, so they concentrate towards the center.
Additionally, the radius of each sample point is jittered by the given
jitter
factor. Parameters:
radius
 the maximum radius of the spiralnumRotations
 the number of rotations of the spiralnumSamples
 the number of samples to generatejitter
 the factor by which the radius of each sample point is jittered. Possible values are[0..1]
callback
 will be called for each sample generated
