Image-Based 3D Modeling: Modeling from Reality

Increasingly, realistic object, scene, and event modeling is based on image data rather than manual synthesis. The paper describes a system for visits to a virtual, 3D archeological site. One can navigate through this environment, with a virtual guide as companion. One can ask questions using natural, fluent speech. The guide will respond and will bring the visitor to the desired place. Simple answers are given as changes in the orientations of his head, by him raising his eyebrows or by head nodding. In the near future the head will speak.
