Abstract

Recently, augmented reality has started to be used in interactively simulating clothes, furnitures, and so on in actual scenes. In such applications, the shading of synthesized CG objects should be matched to those scenes to achieve a sense of reality. Although many techniques have been proposed to match the shading of CG objects to actual scenes, typically they require the use of light probes such as mirrored spheres [Debevec 1998]. However, such light probes are not always available in interactive simulation situations.
