  abstract =     "The computational effort to render images with light
                 sources and camera at infinity is less than with light
                 sources at finite distance from the illuminated
                 surface. On the other hand, in the case of an
                 infinitely remote light source and camera, planar
                 polygons don't receive highlights. In this paper, a
                 method is suggested to use the (relatively cheap)
                 infinite-distance model instead of the expensive
                 finite-distance model for the computation of
                 highlights. It works by replacing a light source at
                 finite distance by a light source at infinite distance,
                 and at the same time adjusting the normal vectors in
                 such a way that the resulting illumination pattern
                 stays the same. With these modifications, a simple
                 table look-up comes in the place of an expensive
                 computation to obtain the specular term in the standard
                 illumination model.",
