Abstract: This invention is directed to a method of efficiently improving a relative density of a shaped object using an evaluation criterion having a higher correlation with a density of an object to be shaped. The method according to this invention includes acquiring three-dimensional point group data of a surface of a shaping object, calculating at least one of three-dimensional surface texture parameters extended to a plane region using the three-dimensional point group data, and evaluating a quality of the object to be shaped using the at least one of the three-dimensional surface texture parameters.
