DATA PROCESSING DEVICE AND METHOD FOR CONVERTING COORDINATES OF A CURVED SURFACE

摘要

A method for converting coordinates of a curved surface is provided. Parameters of the curved surface to be converted are received, and basic data is computed using a B-spline basis function according to the parameters to formulate a data structure. Basic points are determined according to the parameters and the data structure, and coordinates of the curved surface are converted from three-dimensional coordinates to two-dimensional coordinates using the basic points.
