ABSTRACT
Urban scenes are often an important background; they are usually not the main focus, but they provide an important ambiance, without which the scene will lack realism. This chapter introduces a user-assisted modeling approach that allows the user to exploit the repetition pattern of a building façade, thus creating a splitting grammar representation for image texture compressing. It proposes a new user-assistant inverse procedural modeling approach for texture compression, which indicates symmetries and repetitions of building facades through procedural rules. The main idea is to use a user-assisted approach for inverse procedural modeling of facade images and introduce a hybrid representation of lines, points, and procedural textured building model. Point-based modeling for urban scene rendering should follow several important characteristics in order to produce a high-quality visual lossless rendering result. Despite progress, representing and rendering large-scale urban data remains challenging.
