Member Function Documentation

double spica::Envmap::pdfLi ( const Interaction &  pObj, const Vector3d &  dir  ) const

overridevirtual

Compute PDF for the incident direction.

Parameters

[in]	isect	The intersecting point.
[in]	inDir	Incident direction.

Returns

PDF (probability density).

Implements spica::Light.

overridevirtual

Sample incident radiance (Li) at the intersecting point.

Parameters

[in]	pObj	The intersecting point.
[in]	rands	A pair of real random numbers.

Returns

Sampled incident randiance.

Implements spica::Light.
