Abstract
A method of performing anti-aliasing on polynomial curves using only integer arithmetic. The anti-aliasing method includes the steps of: defining an polynomial equation of a curve, dividing grid units into an finite number of sub-intervals, associating a mix ratio to each of the sub-intervals, determining which sub-interval the curve bisects, assigning a mix ratio to each picture element bordering the grid unit according to the mix ratio associated with the sub-interval determined to be bisected by the curve.
