Member Function Documentation

color_t glossyMat_t::eval	(	const renderState_t &	state,
		const surfacePoint_t &	sp,
		const vector3d_t &	wo,
		const vector3d_t &	wl,
		BSDF_t	types
	)			const `[virtual]`

evaluate the BSDF for the given components.

Parameters:

types

the types of BSDFs to be evaluated (e.g. diffuse only, or diffuse and glossy)

Implements material_t.

void glossyMat_t::initBSDF	(	const renderState_t &	state,
		const surfacePoint_t &	sp,
		BSDF_t &	bsdfTypes
	)			const `[virtual]`

Initialize the BSDF of a material. You must call this with the current surface point first before any other methods (except isTransparent/getTransparency)! The renderstate holds a pointer to preallocated userdata to save data that only depends on the current sp, like texture lookups etc.

Parameters:

bsdfTypes

returns flags for all bsdf components the material has

Implements material_t.

float glossyMat_t::pdf	(	const renderState_t &	state,
		const surfacePoint_t &	sp,
		const vector3d_t &	wo,
		const vector3d_t &	wi,
		BSDF_t	bsdfs
	)			const `[virtual]`

return the pdf for sampling the BSDF with wi and wo

Reimplemented from material_t.

color_t glossyMat_t::sample	(	const renderState_t &	state,
		const surfacePoint_t &	sp,
		const vector3d_t &	wo,
		vector3d_t &	wi,
		sample_t &	s
	)			const `[virtual]`

take a sample from the BSDF, given a 2-dimensional sample value and the BSDF types to be sampled from

Parameters:

s

s1, s2 and flags members give necessary information for creating the sample, pdf and sampledFlags need to be returned

Implements material_t.

bool glossyMat_t::scatterPhoton	(	const renderState_t &	state,
		const surfacePoint_t &	sp,
		const vector3d_t &	wi,
		vector3d_t &	wo,
		pSample_t &	s
	)			const `[virtual]`

specialized function for photon mapping. Default function uses the sample function, which will do fine for most materials unless there's a less expensive way or smarter scattering approach

Reimplemented from material_t.
