Abstract
Curve drawing is a fundamental aspect of computer graphics. It occurs in a great variety of different applications. The scientist or engineer, having observed or calculated a sequence of data values, will frequently wish to display an estimate of the function underlying these values by drawing a curve through the data points. If the data points are known to be subject to error, the problem changes to one of drawing a smooth curve which best approximates the data. The cartographer may use curve drawing to depict the boundary of a region, given only a discrete set of boundary points. The designer of a ship or motor car, starting from some initial trial curve will wish to transform it interactively into some desired shape. The animator too will make use of curve drawing in the production of cartoons — not only for pictures on individual frames, but also to construct automatically ‘in-between’ frames, where corresponding points on successive ‘key’ frames are interpolated by a curve to give a smooth transition.
