Abstract
A method and apparatus implementing a technique for entering a representation of a desired curve into a computer. In one aspect, the technique includes receiving an ordered sequence of points representing the desired curve as input. The points of the sequence of points are grouped into one or more contiguous segments of points. The points of each segment are smoothed to generate a segment of smoothed points for each segment. One or more mathematical curves are fitted to each segment of smoothed points. Together, the one or more mathematical curves from each segment of smoothed points form the representation of the desired curve.
