Facade is a system developed by Paul Debevec, C. J. Taylor, and Prof. Jitendra Malik for modeling and rendering 3-D architectural models from photographs. Until recently, the reconstruction capabilities of Facade were limited to polyhedral structures such as boxes, frustums, octagons, etc. The rendering algorithms were computationally expensive. Facade needed tools for recovery of some non-polyhedral structures appearing in architecture. The first part of this work describes a new set of tools for recovery of surfaces of revolution and arches which made a project such as the reconstruction of the majestic Taj Mahal from a single uncalibrated photograph possible. The second part, describes the significant advances made in image-based rendering. New robust ways of performing view-dependent texture mapping are introduced. The novel rendering algorithms allowed us to produce completely photorealistic renderings of flying around the Berkeley tower, the Campanile, and the surrounding campus at speeds close to real-time.
