1. A method of placing an image of a synthetic object into a scene, said method comprising the steps of:

  • securing an omnidirectional image of a said scene to produce a high dynamic range illuminated scene;

    specifying a desired position and orientation of a synthetic object within said high dynamic range illuminated scene;

    partitioning said high dynamic range illuminated scene into a distant scene, a local scene, and said synthetic object;

    computing a global illumination solution of said distant scene while assuming that it is photometrically unaffected by said local scene and said synthetic object; and

    computing a global illumination solution of said local scene that includes shadows and reflected light from said synthetic object.
