Abstract
A method of placing an image of a synthetic object into a scene includes the step of establishing a recorded field of illumination that characterizes variable incident illumination in a scene. A desired position and orientation of a synthetic object is specified within the scene with respect to the recorded field of illumination. A varying field of illumination caused by the synthetic object is identified within the scene. Synthetic object reflectance caused by the synthetic object is simulated in the scene. The synthetic object is then constructed within the scene using the varying field of illumination and the synthetic object reflectance.
