Up: up A Fast and Accurate Light Reflection Model
Previous: previous Abstract
Next: next Geometrical Parameters


There have been many efforts in Computer Graphics to develop physically-based light reflection models [BLIN77, COOK82, HE91, KAJI85, PHON75].

Reflection models are generally presented in terms of a bidirectional reflectance distribution function (BRDF)

ρ_bd = dI_r/dE_i (1)

where dIr is the reflected radiance or intensity, measured in watts per meter-squared per steradian, and dEi is the incident energy flux, measured in watts per meter-squared. In general, the BRDF is a function of many parameters which can be divided into two groups, i.e., geometrical parameters and physical parameters.
