Abstract
A method and system for implementing capturing and rendering geometric details for mesostructure surfaces is described herein. A mesostructure distance function is defined as a function of a given reference point and a given viewing direction. A distance from a reference point to a mesostructure surface point along a viewing direction is measured using the mesostructure distance function. This distance is used to determine the visibility of mesostructure surface for rendering silhouettes. The lighting visibility of the mesostructure surface point may also be determined and used for determining whether the mesostructure surface point is in shadow. This determination may then be used for rendering shadow silhouettes.
