Abstract:
1. A computer program product for use in connection with a computer to provide a fine-to-coarse level mesh generating arrangement for generating a coarse level mesh representation representing a surface, from a finer level mesh representation, the computer program product comprising a computer-readable medium having encoded thereon: A. computer-readable program instructions executable to provide an indicator value generator module configured to enable the computer to, for respective ones of the points in the finer level surface representation, evaluate an indicator function to generate an indicator value; B. computer-readable program instructions executable to provide a coarse level mesh generator module configured to enable the computer to determine, for each of the points; and C. computer-readable program instructions executable to provide a Laplacian generator module configured to enable the computer to generate a Laplacian value for said respective ones of the points in the finer level mesh representation; in which the Laplacian generator module is configured to generate the Laplacian value L(k,j+1), for at least one of said points, said at least one of said points comprising a point on a boundary, crease line or the like in a triangular mesh representation, in accordance with where c j+1 (k) represents the position of the point for which the Laplacian is being generated in the finer level mesh representation, and c j+1 (k−1) and c j+1 (k+1) represent the positions of neighboring points in the finer level mesh representation.
