Description:
The first part of this video describes UC Berkeley’s Facade photogrammetric modeling system, emphasizing developments made since it was presented in the SIGGRAPH 96 paper “Modeling and Rendering Architecture from Photographs”. Facade allows a user to build photorealistic models of architectural scenes from a small number of still photographs. Recent developments allow for the recovery of arches and surfaces of revolution and can render the recovered models in real time on standard graphics hardware.
The second part of the video is a creative piece entitled “The Campanile Model” which plays on the visual relationship between Berkeley’s bell tower, a model miniature of the tower, and a computer model of the tower and surrounding environment. The computer model was created with the Facade system from twenty photographs, including a few photographs taken above the tower from a kite. This model represents the first time a fully immersive and photorealistic model of a real place has been captured. Significantly, this technique allows the director to experiment with and control the path of the camera during post-production, to match virtual camera motion to real camera motion, and to produce camera motion that would be impossible to produce with conventional photographic techniques.
In its principal shot, the film makes four transitions between reality and the virtual environment by matching the virtual camera motion to the real, handheld, camera motion recovered using the Facade system. A custom keyframe animation technique was developed to smoothly bridge the segments of recovered camera motion with arbitrary virtual flight paths.
