scat - Scattering function (either Phong or HG)

hg - use Henyey-Greenstein phase function scattering

Method Detail

getBSDF

public IBSDF getBSDF()

Specified by:

getBSDF in interface IMaterial

Returns:

null since a dielectric material has no diffuse reflection

getSPF

public ISPF getSPF()

Specified by:

getSPF in interface IMaterial

Returns:

the scattering function

getEmitter

public IEmitter getEmitter()

Specified by:

getEmitter in interface IMaterial

Returns:

the emission properties for this material
null if there is not an emitter

getCopy

public IMaterial getCopy()

Specified by:

getCopy in interface IMaterial

Returns:

a copy of the material
