virtual PSSMLTPathSampler* PSSMLTPathSampler::Clone ( ) const

pure virtual

Clone the sampler.

Returns: Duplicated instance.

Implemented in PSSMLTBPTPathSampler, and PSSMLTPTPathSampler.

virtual bool PSSMLTPathSampler::Configure	(	const ConfigNode &	node,
		const Assets &	assets
	)

pure virtual

Configure the sampler from XML element.

Parameters

node	A XML element which consists of path_sampler element.
assets	Assets manager.

Return values

true	Succeeded to configure.
false	Failed to configure.

Implemented in PSSMLTBPTPathSampler, and PSSMLTPTPathSampler.

virtual void PSSMLTPathSampler::SampleAndEvaluate	(	const Scene &	scene,
		Sampler &	sampler,
		PSSMLTSplats &	splats,
		int	rrDepth,
		int	maxPathVertices
	)

pure virtual

Sample and evaluate light paths. Light path sampling strategy such as BPT might generate multiple light paths which contribute different raster position. We represent these different contributions by PSSMLTSplats structure.

Parameters

scene	Scene.
sampler	Abstract sampler.
splats	Evaluated pixel contributions and their raster positions.
rrDepth	Depth to begin RR, -1 skips RR.
maxPathVertices	Maximum number of vertex, -1 specifies no limits.

Implemented in PSSMLTBPTPathSampler, and PSSMLTPTPathSampler.

virtual void PSSMLTPathSampler::SampleAndEvaluateBidir	(	const Scene &	scene,
		Sampler &	subpathSamplerL,
		Sampler &	subpathSamplerE,
		PSSMLTSplats &	splats,
		int	rrDepth,
		int	maxPathVertices
	)

pure virtual

Sample and evaluate light paths (separated PSS version for BPT). Primary sample spaces is separated into two parts: for sampling light subpath and eye subpath, which increase coherency between mutations.

Parameters

scene	Scene.
subpathSamplerL	Abstract sampler for light subpath.
subpathSamplerE	Abstract sampler for eye subpath.
splats	Evaluated pixel contributions and their raster positions.
rrDepth	Depth to begin RR, -1 skips RR.
maxPathVertices	Maximum number of vertex of each subpath, -1 specifies no limits.

Implemented in PSSMLTBPTPathSampler, and PSSMLTPTPathSampler.

virtual void PSSMLTPathSampler::SampleAndEvaluateBidirSpecified	(	const Scene &	scene,
		Sampler &	subpathSamplerL,
		Sampler &	subpathSamplerE,
		PSSMLTSplat &	splat,
		int	rrDepth,
		int	maxPathVertices,
		int	s,
		int	t
	)

pure virtual

Sample and evaluate light paths (separated PSS version for BPT) for specified technique. A variant of SampleAndEvaluateBidir with specified technique with #s and #t.

Parameters

scene	Scene.
subpathSamplerL	Abstract sampler for light subpath.
subpathSamplerE	Abstract sampler for eye subpath.
splat	Evaluated pixel contribution and its raster position.
rrDepth	Depth to begin RR, -1 skips RR.
maxPathVertices	Maximum number of vertex of each subpath, -1 specifies no limits.
s	Number of light subpath vertices.
t	Number of eye subpath vertices.

Implemented in PSSMLTBPTPathSampler, and PSSMLTPTPathSampler.
