Constructor Details

SpiralSampling

public SpiralSampling(long seed)

Create a new instance of SpiralSampling and initialize the random number generator with the given seed.

Parameters:

seed - the seed to initialize the random number generator with

Method Details

createEquiAngle

public void createEquiAngle(float radius,
 int numRotations,
 int numSamples,
 Callback2d callback)

Create numSamples number of samples on a spiral with maximum radius radius around the center using numRotations number of rotations along the spiral, and call the given callback 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 spiral

numRotations - the number of rotations of the spiral

numSamples - the number of samples to generate

callback - will be called for each sample generated

createEquiAngle

public void createEquiAngle(float radius,
 int numRotations,
 int numSamples,
 float jitter,
 Callback2d callback)

Create numSamples number of samples on a spiral with maximum radius radius around the center using numRotations number of rotations along the spiral, and call the given callback 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 spiral

numRotations - the number of rotations of the spiral

numSamples - the number of samples to generate

jitter - 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
