Abstract
A glossy part of a radiation coming from a surface illuminated by area light source(s) (21) having source surface(s) (A) bounded by edge curves (210) is estimated, by determining integrand function(s) representative of that glossy part - the latter corresponding to an integration of the integrand function along the edge curves. In this respect, the integrand function(s) is/are approximated by means of peak-shape function(s) having a known antiderivative over the edge curves, and the glossy part is computed from analytical expressions associated with integrations of the peak-shape function(s) along the edge curves. That can offer efficient and accurate computation for specular part of reflection as well as glossy transmission, and is notably relevant to real-time rendering.
