Abstract

Desk lamps, automobile headlights, streets lamps,..., usually illuminate by light cones. This article describes two methods adapted to simulate those typical light sources, using a CSG model, in a Ray Tracing environment. These methods allow to visualize illuminated objects but also the light beams. The first one is completely empirical; the second one is an improvement of the previous one, physically-based, with spherical particles inside the light beam.
