Claim One:
1. A method for producing a visual representation of a curve image from a set of control points which define the curve and which are input for each dimension and a number of intervals of the curve to be computed, said method comprising the steps of: (a) computing a set of scaled vector coefficient integers for each dimension from the set of input control points for that dimension and from a scaling parameter; (b) computing forward difference interval coefficient integers for each dimension for each interval from the scaled vector coefficient integers for that dimension and the interval integer number; (c) computing the curve coordinate values for each interval for each dimension from the forward difference interval coefficient integers for that dimension for each interval and the scaling parameter; and (d) displaying the curve by displaving curve coordinate points in accordance with the computed curve coordinate values for each dimension and a plurality of straight lines which successively connect said computed curve coordinate points.
