Some of the best current research on realistic rendering is
included in this volume. It emphasizes the current "hot topics in
this field: image based rendering, and efficient local and
global-illumination calculations. In the first of these areas,
there are several contributions on real-world model acquisition and
display, on using image-based techniques for illumination and on
efficient ways to parameterize and compress images or light fields,
as well as on clever uses of texture and compositing hardware to
achieve image warping and 3D surface textures. In global and local
illumination, there are contributions on extending the techniques
beyond diffuse reflections, to include specular and more general
angle dependent reflection functions, on efficiently representing
and approximating these reflection functions, on representing light
sources and on approximating visibility and shadows. Finally, there
are two contributions on how to use knowledge about human
perception to concentrate the work of accurate rendering only where
it will be noticed, and a survey of computer graphics techniques
used in the production of a feature length computer-animated film
with full 3D characters.
