function
MinSG::AGVS::SampleDistributions::generateSample

public

const

Sample < float > generateSample(	) const

Generate a sample from a random sample distribution.

function
MinSG::AGVS::SampleDistributions::updateWithSample

public

void updateWithSample(	const Sample < float > &	sample,
	const contribution_t &	contribution,
	ValuatedRegionNode *	viewCell
)

Use the contribution of a sample to update the contribution of the sample distributions.

Parameters

sample

New sample used to update the view cells

contribution

Pair of forward and backward contribution of the sample

viewCell

View cell containing the origin of the sample

_{Defined in MinSG/Ext/AdaptiveGlobalVisibilitySampling/SampleDistributions.h:56}

function
MinSG::AGVS::SampleDistributions::calculateDistributionProbabilities

public

void calculateDistributionProbabilities(	)

Update the probabilities used to select the sample distribution.

function
MinSG::AGVS::SampleDistributions::terminate

public

const

bool terminate(	) const

Estimate the pixel error. Check if the estimated pixel error is below a treshold and the probability that it is similar to the real error is high.

Returns

trueif the sampling is finished,falseotherwise
