Detailed Description

template<typename BSDFMODEL, size_t samplesTheta = 90, size_t samplesPhi = 1, string_literal NAME = BSDFMODEL::name>
struct bbm::ndf_sampler< BSDFMODEL, samplesTheta, samplesPhi, NAME >::backscatter

Helper Class: Backscatter NDF passthrough.

Wraps the BSDF model's eval function in an NDF eval; other NDF methods are unevaluable. This is used to construct an ndf::sampler
