  abstract =     "Many scattering models have been presented in the
                 graphics literature. Few of them, however, have been
                 evaluated through comparisons with real measured data.
                 As the demand for plausible and predictable scattering
                 models increases, more attention is given to performing
                 such comparisons. In this paper we examine the
                 implementation of virtual goniphotometers used to
                 obtain BRDF (bidirectional reflectance distribution
                 function) and BTDF (bidirectional transmittance
                 distribution function) records from algorithmic
                 scattering models. These records can be compared to
                 data from actual experiments in order to validate the
                 models. Our discussion focuses on practical issues,
                 namely the subdivision of the devices' collector sphere
                 and the ray density required to obtain reliable BRDF
                 and BTDF estimates. The subdivision techniques examined
                 in this paper have been used before in publications,
                 but the details of their computation are not readily
                 available in the literature. Although the mathematical
                 bound presented to determine appropriate ray densities
                 for virtual goniphotometers is a direct generalization
                 of a bound used for virtual spectrophotometers, it has
                 not been published before. Our discussion of these
                 issues is supported by practical experiments whose
                 results are also provided in this paper.",
