In this paper we present a physical validation of global illumination algorithms based on measurements from a simple experimental setup. The validation methodology emphasises tractability and error minimisation. To this end, we discuss issues such as the acquisition and accurate simulation of material BRDFs and the light source distribution , as well as(More)
Physically based image synthesis remains one of the most demanding tasks in the computer graphics field, whose applications have evolved along with the techniques in recent years, particularly with the decline in cost of powerful computing hardware. Physically based rendering is essentially a niche since it goes beyond the photore-alistic look required by(More)
