Detailed Description

template<typename BSDF, typename REFERENCE, bsdf_flag COMPONENT = bsdf_flag::All, unit_t UNIT = unit_t::Radiance>
requires concepts::matching_config<BSDF, REFERENCE> && concepts::bsdfmodel<BSDF> && concepts::bsdfmodel<REFERENCE>

standardLog loss function

Template Parameters

BSDF	= bsdf to optimize
REFERENCE	= bsdf to match
COMPONENT	= which bsdf component to optimize
UNIT	= unit over which to optimize

standardLog is a sampled loss function that computes the loss over two BSDFs using the standardLog_error and a spherical sampling of in and out directions (spherical_linearizer).

Implements: concepts::sampledlossfunction
