Layered lumigraph with LOD control

The rendering performance of an image-based rendering (IBR) system depends on the number of images and the amount of geometry information used. In this paper, we propose the layered lumigraph representation that is configured for optimized rendering performance given the rendering platform (e.g., processor speed, memory, etc.) and the output image resolution. The layered lumigraph is produced by classifying all pixels into a number of depth layers. Based on the prior plenoptic sampling analysis work, the layered lumigraph is constructed to achieve the same rendering quality along the minimum sampling curve by trading off the number of images and depth ∗3F Beijing Sigma Center, No. 49 Zhichun Road, Haidian District, Beijing 100080, P.
