Abstract:

This paper presents an overview of techniques for generating photoreal computer graphics models of real-world places and objects. Our groups early efforts in modeling scenes involved the development of Facade, an interactive photogrammetric modeling system that uses geometric primitives to model the scene, and projective texture mapping to produce the scene appearance properties. Subsequent work has produced techniques to model the incident illumination within scenes, which we have shown to be useful for realistically adding computer-generated objects to image-based models. More recently, our work has focussed on recovering lighting-independent models of scenes and objects, capturing how each point on an object reflects light. Our latest work combines three-dimensional range scans, digital photographs, and incident illumination measurements to produce lighting-independent models of complex objects and environments.
