1. A method for reducing three-dimensional shape data, comprising the steps of:

  • calculating estimation values for surfaces to be deformed by shrinking edges or surfaces of a polygon model by converging two or more vertices of the polygon model based on distances between the respective surfaces and all the original vertices involved in the surface deformation;

    comparing calculated estimation values with a predetermined permissible value; and

    reducing the number of data for the polygon model by shrinking edges or surfaces of the polygon model when the estimation values are equal to or below the predetermined permissible value.
