		const Vec3D &	wInc,
		Intersection &	is
	)			[virtual]

Parameters:

	wOut	The outgoing direction.

		const Vec3D &	wInc,
		Intersection &	is
	)			[virtual]

Parameters:

	wOut	The outgoing direction. Should be the reflected direction of wInc (and vice versa)
	wInc	The incoming direction.
	is	The Intersection data.

ScatterEvent rcrt::BSDFMaterial::scatterPhoton	(	Intersection &	is,
		Photon *	photon
	)			[virtual]

Scatters a Photon.

Parameters:

	is	The Intersection data. Currently this also includes a previous IOR. //TODO refactor the ior stuff
	photon	A photon, this should be set to the intersection point, a new outgoing direction and should be scaled in power according to the sampling process.
