  abstract =     "The radiosity method is a finite element global
                 illumination technique that usually involves the
                 discretization of the environment being modeled and
                 estimating the light transported between the resulting
                 elements. The computed result, a collection of patches
                 and their estimated radiances, does not produce a very
                 realistic image and often the reconstruction of the
                 illuminance functions over each visible surface is
                 necessary. The more sophisticated of these
                 reconstruction techniques perform a local gathering
                 step at closely spaced sample points, typically one per
                 pixel. This paper describes an algorithmic framework
                 for implementing this final gathering pass that allows
                 one to adaptively control the spacing of sample points
                 in order to minimize the number of computationally
                 expensive local gather operations while still achieving
                 a rendered image of acceptable quality.\par The basic
                 algorithm is independent of the method by which the
                 global illumination solution is obtained but can easily
                 be tuned for specific models and surfaces. The method
                 is also easily extended to allow the shading of curved
                 surfaces within a radiosity environment.",
