<p num="1"><br/><br/> METHOD OF CURVE APPROXIMATION<br/><br/><br/><br/> ABSTRACT OF THE DISCLOSURE<br/><br/><br/> A method of curve approximation comprises a dividing<br/>step for dividing a curve into arcs classified into four<br/>quadrant directions according to a normal thereof, each<br/>having a single-value monotone increasing or decreasing<br/>function, and a calculating step for calculating an<br/>approximate curve represented by a curve approximation<br/>function by using an interval between end points of each<br/>arc as a curve approximation interval.<br/> |
