Abstract
A surface light field is a function that assigns a color to each
ray originating on a surface. Surface light fields are well suited
to constructing virtual images of shiny objects under complex
lighting conditions. This paper presents a framework for construction,
compression, interactive rendering, and rudimentary editing
of surface light fields of real objects. Generalizations of vector
quantization and principal component analysis are used to construct
a compressed representation of an object’s surface light field from
photographs and range scans. A new rendering algorithm achieves
interactive rendering of images from the compressed representation,
incorporating view-dependent geometric level-of-detail control.
The surface light field representation can also be directly edited
to yield plausible surface light fields for small changes in surface
geometry and reflectance properties.
