Abstract
A new BRDF model is presented which can be viewed as an kind of
intermediary model between empirism and theory. Main results of
physics are observed (energy conservation, reciprocity rule,
microfacet theory) and numerous phenomena involved in light reflection
are accounted for, in a physically plausible way (incoherent and
coherent reflection, spectrum modifications, anisotropy,
self-shadowing, multiple surface and subsurface reflection,
differences between homogeneous and heterogeneous materials). The
model has been especially intended for computer graphics applications
and therefore includes two main features : simplicity (a small
number of intuitively understandable parameters controls the model)
and efficiency (the formulation provides adequation to
Monte-Carlo rendering techniques and/or hardware implementations).
