METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR 3D OBJECTS GRAPHICAL REPRESENTATION

摘要

A method and system for generating a three-dimensional (3D) multi-resolution meshing structure is provided. The 3D multi-resolution meshing structure is obtained in a two-steps simplification and refinement process that does not require a 3D-to-2D parameterization phase and wherein the geometry of the surface of the 3D object is used during the refinement step.

1. A computer implemented method of generating a three-dimensional (3D) multi-resolution meshing structure having ‘n’ levels of details, the method comprising the steps of:
creating a base mesh from a 3D input mesh; and iteratively refining the base mesh to match the surface of the 3D input mesh by:
applying a regular subdivision on a ith level of detail of the base mesh to obtain a (i+1)th level of detail; andoptimizing the (i+1)th level of detail by applying a constrained vertex clustering method on the surface of the 3D input mesh.
