摘要
A computer-based method for determining a property of a location on a computer surface model where the location is described by a set of parameters and the surface model is described by a set of control vertices having a corresponding set of subdivision rules, and the control vertices admit a parameterization of regular sets of control vertices, includes receiving input specifying coordinates of control vertices that describe the surface model, projecting the specified coordinates of the control vertices into an eigenspace derived from a matrix representation of the subdivision rules to produce a set of projected control vertices, determining which of a hierarchically nested set of regular tiles of the surface model contains the location, and evaluating the location as a function of a valence of one of the control vertices, the determined nested tile, and the set of projected control vertices. The evaluated location is stored in a computer memory.
