Approximation of a Cubic Bezier Curve by Circular Arcs and vice Versa
نویسنده
چکیده
In this paper problem for converting a circular arc into cubic Bezier arc and approximation of cubic Bezier curve by a set of circular arcs are discussed. These questions occur in CAD/CAM systems during data exchange from data formats which support Bezier curves or during data exchange into data formats, which do not support Bezier curves. Some simple and practical solutions are proposed. An algorithm for approximation of a cubic Bezier curve and the results of its testing are presented.

An Improved Algorithm for the Approximation of a Cubic Bezier Curve and its Application for Approximating Quadratic Bezier Curve
In this paper an improved version of an earlier proposed algorithm for approximating cubic Bezier curve by a set of circular arcs is presented. It is investigated how the improved algorithm fits for approximation of quadratic Bezier curves. These issues occur in CAD/CAM systems during data exchange into data formats which do not support Bezier curves. Experimental results on examples, widely us...
متن کاملApproximation of Circular Arcs Using Quartic Bezier Curves with Barycentric Coordinates Satisfying G Data
This paper proposes four methods to approximate circular arcs using quartic Bezier curves. Barycentric coordinates of two/three combination of control points are used to obtain an optimal approximation. Interior control points of quartic Bezier curves are found by satisfying G data from given circular arcs. The maximum errors between circular arcs and approximated curves are calculated using Ha...
متن کاملCapturing Outlines of Planar Generic Images by Simultaneous Curve Fitting and Sub-division
In this paper, a new technique has been designed to capture the outline of 2D shapes using cubic B´ezier curves. The proposed technique avoids the traditional method of optimizing the global squared fitting error and emphasizes the local control of data points. A maximum error has been determined to preserve the absolute fitting error less than a criterion and it administers the process of curv...
متن کاملHigher order Bézier circles
Rational Bezier and B-spline representations of circles have been heavily publicized. However, all the literature assumes the rational Bezier segments in the homogeneous space are both planar and (equivalent to) quadratic. This creates the illusion that circles can only be achieved by planar and quadratic curves. In this paper we show circles that are formed by higher order rational Bezier curv...
متن کاملApproximating Maximum Speed on Road from Curvature Information of Bezier Curve
Abstract—Bezier curves have useful properties for path generation problem, for instance, it can generate the reference trajectory for vehicles to satisfy the path constraints. Both algorithms join cubic Bezier curve segment smoothly to generate the path. Some of the useful properties of Bezier are curvature. In mathematics, curvature is the amount by which a geometric object deviates from being...
