Basic concepts of physically-based rendering
Article No.: 3, Pages 1 - 11
Abstract
This tutorial will cover the basics of physically-based rendering such as reflection models (BRDF), volume scattering (phase functions), optical phenomena (dispersion and polarization). It will also cover image formation via basic camera models. A brief summary of popular algorithms will be covered including radiosity, path tracing, photon tracing, and Metropolis Light Transport. The course will end with a more detailed description of adjoint photon tracing so that attendees can later implement their own physically-based renderer.
