Member Function Documentation

virtual int DielectricBSDF::BSDFTypes ( ) const

inlineoverridevirtual

Check if generalized BSDF is directionally degenerated. e.g. specular BSDFs or directional light

Return values

true	The BSDF is directionally degenerated.
false	The BSDF is not directionally degenerated.

Get generalized BSDF type. If the generalized BSDF has multiple types, e.g. SpecularReflection and SpecularReflection, a bitmask of these types are returned.

Returns: Types.

Implements GeneralizedBSDF.

Math::Vec3 DielectricBSDF::EvaluateDirection	(	const GeneralizedBSDFEvaluateQuery &	query,
		const SurfaceGeometry &	geom
	)		const

overridevirtual

Evaluate generalized BSDF.

Parameters

query	Query structure.
geom	Surface geometry.

Returns: Evaluated contribution.

Implements GeneralizedBSDF.

Math::PDFEval DielectricBSDF::EvaluateDirectionPDF	(	const GeneralizedBSDFEvaluateQuery &	query,
		const SurfaceGeometry &	geom
	)		const

overridevirtual

Evaluate directional PDF.

Parameters

query	Query structure.
geom	Surface geometry.

Returns: Evaluated PDF.

Implements GeneralizedBSDF.

bool DielectricBSDF::Load	(	const ConfigNode &	node,
		const Assets &	assets
	)

virtual

Load an asset. Configure and initialize the asset by the XML elements given by #node. Some assets have references to the other assets, so #assets is also required. Dependent asset must be loaded beforehand.

Parameters

node	XML node for the configuration.
assets	Asset manager.
true	Succeeded to load.
false	Failed to load.

Implements Asset.

Math::Vec3 DielectricBSDF::SampleAndEstimateDirection	(	const GeneralizedBSDFSampleQuery &	query,
		const SurfaceGeometry &	geom,
		GeneralizedBSDFSampleResult &	result
	)		const

overridevirtual

Sample and estimate direction. Computes f_s / p_{^}.

Parameters

query	Query structure.
geom	Surface geometry.
result	Sampled result.

Returns: Estimate.

Implements GeneralizedBSDF.

bool DielectricBSDF::SampleAndEstimateDirectionBidir	(	const GeneralizedBSDFSampleQuery &	query,
		const SurfaceGeometry &	geom,
		GeneralizedBSDFSampleBidirResult &	result
	)		const

overridevirtual

Sample and estimate direction bidirectionally. In addition to SampleAndEstimateDirection, this function calculates values in the opposite direction. This function is introduced in order to avoid nasty precision problem with specular BSDFs.

Parameters

query	Query structure.
geom	Surface geometry.
weights	Estimate.
results	Sampled results.

Return values

true	Succeeded to sample.
false	Failed to sample.

Implements GeneralizedBSDF.

bool DielectricBSDF::SampleDirection	(	const GeneralizedBSDFSampleQuery &	query,
		const SurfaceGeometry &	geom,
		GeneralizedBSDFSampleResult &	result
	)		const

overridevirtual

Sample outgoing vector. Given the input direction originated from the point on the surface #wi, the function samples outgoing vector #wo from the suited distribution in the solid angle measure.

Parameters

query	Query structure.
geom	Surface geometry.
result	Sampled result.

Return values

true	Succeeded to sample #wo.
false	Failed to sample #wo.

Implements GeneralizedBSDF.
