Online Construction of Surface Light Fields

by Greg Coombe, Chad Hantak, Anselmo Lastra, Radek Grzeszczuk



Abstract

We present a system for interactively capturing, constructing, and rendering surface light fields by incrementally building a low rank approximation to the surface light field. Each image is incorporated into the lighting model as it is captured, providing the user with real-time feedback. This feedback enables the user to preview the lighting model and direct the image acquisition towards undersampled areas of the object. We also provide a novel data-driven quality heuristic to aid the user in identifying undersampled regions.

I presented this paper at the 2005 Eurographics Symposium on Rendering.
