Detailed Description

Light-scattering phase functions.

Function Documentation

cornette_shanks()

template<class T >

T physics::light::phase::cornette_shanks	(	T	mu,
		T	g
	)

Cornette-Shanks phase function.

Parameters

mu	Cosine of the angle between the light and view directions.
g	Asymmetry factor, on [-1, 1]. Positive values cause forward scattering, negative values cause back scattering.

Definition at line 70 of file phase.hpp.

henyey_greenstein()

template<class T >

T physics::light::phase::henyey_greenstein	(	T	mu,
		T	g
	)

Henyey–Greenstein phase function.

Parameters

mu	Cosine of the angle between the light and view directions.
g	Asymmetry factor, on [-1, 1]. Positive values cause forward scattering, negative values cause back scattering.
