Detailed Description

Modeling Fresnel effects that occur on interfaces.

The two sides of a interface are called inner and outer sides, where outer side has \( \cos(\theta_{indicent})>0 \) and inner side has \( \cos(\theta_{indicent})<0 \).

Constructor & Destructor Documentation

◆ ~FresnelEffect()

virtual ph::FresnelEffect::~FresnelEffect ( )

virtualdefault

Member Function Documentation

◆ calcReflectance()

virtual math::Spectrum ph::FresnelEffect::calcReflectance ( real cosThetaIncident ) const

pure virtual

Parameters

cosThetaIncident Cosine of the incident angle.

Returns: The reflectance of the interface on the specified angle.

Note: cosThetaIncident is signed, so inner and outer sides can be determined.

Implemented in ph::ConductorFresnel, ph::DielectricFresnel, ph::ExactConductorFresnel, ph::ExactDielectricFresnel, ph::SchlickApproxConductorFresnel, and ph::SchlickApproxDielectricFresnel.

◆ calcTransmittance()

math::Spectrum ph::FresnelEffect::calcTransmittance ( real cosThetaIncident ) const
