Interactive walkthrough applications require detailed 3D models
to give users a sense of immersion in an environment.
Traditionally these models are built using computer-aided design
tools to define geometry and material properties. But creating
detailed models is time-consuming and it is also difficult to
reproduce all geometric and photometric subtleties of real-world
scenes. Computer vision attempts to alleviate this problem by
extracting geometry and photogrammetry from images of the real-
world scenes. However, these models are still limited in the
amount of detail they recover.
Image-based rendering generates novel views by resampling a set
of images of the environment without relying upon an explicit
geometric model. Current such techniques limit the size and shape
of the environment, and they do not lend themselves to
