DESCRIPTION

~RiLightObject() ;

Destructor Do nothing

    virtual ~RiLightObject()   
;

Function is currently defined inline.

RiReal GetFormFactorSample(RiLightRegion &sample, const RiMaterialRegion &interestedSample, const RiVector2 &uv);

 Fills in the data in sample, and returns the Form Factor weight for the sample to the interestedSample. interestedSample is used to direct the object so that it will hopefully pick a point visible to the intersted point, reducing variance. Form Factor weight is FFdi,dx / p(x) where p(x) is often the return value from GetSample The actual light arriving at interestedSample is the FFweight * the GetIrradiance() of the sample.
