ABSTRACT:
A high speed and memory efficient method and system for determining with a computer when a curve defined by a set of Bezier, control points is sufficiently approximated by a line segment so that the reduction of the Bezier curve into smaller curves can stop. The method is readily implemented on a computer using vectors formed using vector addition and subtraction and is applicable to Bezier curves of any order.
