Member Function Documentation

◆ calcBsdf()

void ph::SurfaceOptics::calcBsdf ( BsdfEvalQuery & eval ) const

Executes a BSDF evaluation query. Respects sidedness policy.

◆ calcBsdfPdf()

void ph::SurfaceOptics::calcBsdfPdf ( BsdfPdfQuery & pdfQuery ) const

Executes a BSDF sample PDF query. Respects sidedness policy.

◆ genBsdfSample()

void ph::SurfaceOptics::genBsdfSample	(	BsdfSampleQuery &	sample,
		SampleFlow &	sampleFlow ) const

Executes a BSDF sample query. Respects sidedness policy.

◆ getAllPhenomena()

SurfacePhenomena ph::SurfaceOptics::getAllPhenomena ( ) const

inline

Get all phenomena that exist in this surface.

Note: If a surface has any delta phenomenon along with any non-delta phenomenon, it should be treated the same way as a surface with only pure delta phenomenon.

◆ getPhenomenonOf()

virtual ESurfacePhenomenon ph::SurfaceOptics::getPhenomenonOf ( SurfaceElemental elemental ) const

pure virtual

Get the phenomenon of a surface component. One can also setup query for a specific elemental. See BsdfQueryContext.

Implemented in ph::IdealAbsorber, ph::IdealDielectric, ph::IdealDielectricTransmitter, ph::IdealReflector, ph::LambertianReflector, ph::LbLayeredSurface, ph::LerpedSurfaceOptics, ph::OpaqueMicrofacet, ph::OrenNayar, ph::ThinDielectricFilm, ph::ThinDielectricShell, and ph::TranslucentMicrofacet.

◆ numElementals()

SurfaceElemental ph::SurfaceOptics::numElementals ( ) const

inline

Get number of components this surface contains.

See also: getPhenomenonOf().

◆ toString()

std::string ph::SurfaceOptics::toString ( ) const

inlinevirtual

Reimplemented in ph::LambertianReflector, ph::LbLayeredSurface, ph::LerpedSurfaceOptics, ph::OpaqueMicrofacet, ph::OrenNayar, and ph::TranslucentMicrofacet.
