Member Function Documentation

eval()

virtual Color3f Mirror::eval ( const BSDFQueryRecord &  bRec ) const

inlineoverridevirtual

Evaluate the BSDF for a pair of directions and measure specified in code bRec.

Parameters

bRec	A record with detailed information on the BSDF query

Returns

The BSDF value, evaluated for each color channel

Implements BSDF.

Definition at line 29 of file mirror.cpp.

pdf()

virtual float Mirror::pdf ( const BSDFQueryRecord &  bRec ) const

inlineoverridevirtual

Compute the probability of sampling bRec.wo (conditioned on bRec.wi).

This method provides access to the probability density that is realized by the sample() method.

Parameters

bRec	A record with detailed information on the BSDF query

Returns

A probability/density value expressed with respect to the specified measure

Implements BSDF.

Definition at line 34 of file mirror.cpp.

sample()

virtual Color3f Mirror::sample ( BSDFQueryRecord &  bRec, const Point2f &  sample  ) const

inlineoverridevirtual

Sample the BSDF and return the importance weight (i.e. the value of the BSDF * cos(theta_o) divided by the probability density of the sample with respect to solid angles).

Parameters

bRec	A BSDF query record
sample	A uniformly distributed sample on

Returns

The BSDF value divided by the probability density of the sample sample. The returned value also includes the cosine foreshortening factor associated with the outgoing direction, when this is appropriate. A zero value means that sampling failed.

Implements BSDF.
