    From photographs to procedural facade models



    The network-based visualization of large photo-realistic 3D landscape and city models has received significant attention over the last five years in the computer graphics and network community. To make such 3D geoweb services appealing to a large audience, 3D city models must reach a sufficient level of realism and faithfulness. The first problematic was the transmission and visualization of such complex models that required the use of view-dependent, compact and progressive representations. The combination of a multiresolution footprint based representation called PBTree [Royan et al. 2006] associated with a procedural based modeling of facades [Mueller et al. 2006] has proved its great efficiency for 3D geoweb applications. Secondly, the procedural modeling of buildings from real world acquisition is not so obvious. Therefore we will present next a solution to determine the structure of facades, in order to model real buildings using a procedural approach. Only the image based acquisition will be considering next, due to its low production cost and storage requirements.
