【Abstract】 The paper presents a local greedy algorithm that minimizes the energy defined by a variational mesh approximation.The algorithm simplifies the mesh by controlling the number of target polygons,while attempting to gain ideal effect from adaptively selected seed triangles.The algorithm has an intuitive geometric meaning.The algorithm is efficient enough to be efficiently adopted in the geometric modeling system.更多还原
