![]() We apply the general method to the problem of rendering synthetic objects into real scenes. A differential rendering technique allows for good results to be obtained when only an estimate of the local scene reflectance properties is known. Renderings are created with a standard global illumination method by simulating the interaction of light amongst the three components. The local scene is endowed with estimated reflectance model information so that it can catch shadows and receive reflected light from the new objects. The distant scene is assumed to be pho-tometrically unaffected by the objects, obviating the need for re-flectance model information. To compute the illumination, the scene is considered as three components: the distant scene, the local scene, and the synthetic objects. ![]() The method uses a high dynamic range image-based model of the scene, rather than synthetic light sources, to illuminate the new objects. We present a method that uses measured scene radiance and global illumination in order to add new objects to light-based models with correct lighting.
