Detailed Description

Kelemen's primary sample. Represents an element of the primary sample space. The class shares the same interface as generic Sampler class, so we can use this class to sample light paths without modification of the implementation of path samplers. The function is also responsible for the lazy evaluation of the mutations which is required to support infinite dimension space. For details, see the original paper.

Member Function Documentation

virtual void PSSMLTPrimarySampler::Accept ( )

pure virtual

Accept mutation. Indicates to accept mutated samples.

Implemented in PSSMLTPrimarySamplerImpl.

virtual void PSSMLTPrimarySampler::BeginRestore ( RewindableSampler & rewindableSampler )

pure virtual

Begin to restore samples. Begins to set internal sample state using the restored sequence of samples with rewindable sampler. Path sampling process dispatched between BeginRestore and EndRestore is recorded in a form of primary samples.

Parameters

rewindableSampler Rewindable sampler.

See also: EndRestore

Implemented in PSSMLTPrimarySamplerImpl.

virtual void PSSMLTPrimarySampler::Configure	(	Random *	rng,
		const Math::Float &	s1,
		const Math::Float &	s2
	)

pure virtual

Configure the sampler. Configure and initializes the sampler. This function must be called before use.

Parameters

rng	Random number generator.
s1	Lower bound of the kernel.
s2	Upper bound of the kernel.

Implemented in PSSMLTPrimarySamplerImpl.

virtual void PSSMLTPrimarySampler::EnableLargeStepMutation ( bool enable )

pure virtual

Enable large step mutation. Enables to use large step mutation in the next mutation step.

Parameters

enable Enabled if true.

Implemented in PSSMLTPrimarySamplerImpl.

virtual void PSSMLTPrimarySampler::EndRestore ( )

pure virtual

End to restore samples. Corresponds to BeginRestore.

See also: BeginRestore

Implemented in PSSMLTPrimarySamplerImpl.

virtual bool PSSMLTPrimarySampler::LargeStepMutation ( ) const

pure virtual

Check if current mutation is large step mutation.

Return values

true	Current mutation is large step mutation.
false	Current mutation is small step mutation.

Implemented in PSSMLTPrimarySamplerImpl.

virtual void PSSMLTPrimarySampler::Reject ( )

pure virtual

Reject mutation. Indicates to reject mutated samples. The internal state is restored to previous state.

Implemented in PSSMLTPrimarySamplerImpl.
