ABSTRACT:
A method for expressing an approximate curve of an original curve by approximately expressing the original curve such as Bezier curve using matrix dots, comprises finding first and second coordinates of three consecutive dots of the approximate curve; and then finding a third coordinate of the three consecutive dots of the approximate curve on the basis of a difference between value of parameter "t" used for determining the coordinates of the first dot and that used for determining the coordinates of the second dot.
