Photorealistic rendering strives to generate images from
computer modeled scenes with an image quality as close to
real life as possible. A major issue in rendering is
simulation of local and global light reflection in a scene.
Both ray tracing and radiosity algorithms capture only some
of the possible light reflection phenomena. Recently
developed two-pass algorithms combine the ray tracing and
radiosity approaches and are able to capture the whole range
of light reflection.
This book is a collection of papers discussing the latest
developments, including a new range of improvements, in
stochastic sampling strategies, radiosity form factor
calculation, and parallel processing for ray tracing and
radiosity. A number of papers on rendering applications in
interior design, lighting design, and remote sensing
conclude the volume.
The contributions are revised versions of papers originally
presented at the Second Eurographics Workshop on Rendering,
held in Barcelona, Spain, in May 1991. The book fully
reflects the state of the art in rendering and presentsa
wide variety of novel techniques. It will interest
researchers and students in computer graphics, as well as
designers who want to apply rendering techniques for
realistic simulation in lighting design, interior design,
