Abstract

This paper presents a method to approximate Beziercurves by a sequence of arc splines with inscribed regular polygon. The proposed algorithm uses the arc length approximation method in subdividing a Bezier curve into subcurves which have equal arc length. Each subcurve is interpolated with a line segment which is a side of the inscribed polygon of a curve. Curve segments are then clustered into a circular arc by evaluating interior angles of inscribed polygon. This method represents a Bezier curve with the minimum number of circular arcs and acceptable errors. The experimental results are provided the similarity of original curve and approximated arc spline. The approximated arc spline which is the result of proposed algorithm is compatible for vector and raster graphic format.
