A numerical method for rendering spherical reflections

Methods of rendering reflections in curved surfaces are examined. A numerical algorithm to derive spherical reflections is presented. This algorithm has many attractive qualities, such as low computation costs, object space coherence, device and resolution independence, and generation of maximum information about reflections in curved surfaces. The authors demonstrate that rendering reflections is a difficult problem, as it defies analytic solutions. The authors indicate several alternatives for generalizing this method to a broader domain
