Abstract: We introduce the notion of spatially encoded video and use it for efficiently representing image-based impostors for interactive walkthroughs. As part of a pre-process, we automatically decompose the model and compute the far-fields. The resulting texture images are organized along multiple dimensions and can be accessed in a user-steered order at interactive rates. Our encoding algorithm can compress the impostors size by two orders of magnitude. Furthermore, the storage cost for additional impostors or samples grows sublinearly. The resulting system has been applied to a complex CAD environment composed of million triangles. We are able to render it at interactive rates on a PC with little loss in image quality. Keywords: image databases, image-based rendering, MPEG, rendering systems, spatial data structures 1
