✦ Synopsis

When a quadratic NURBS curve is used to describe the path of a computer-controlled cuttin9 machine, the NURBS curve is usually approximated by many straight-line segments. It is preferable to describe the cutting path as an arc spline, a tangent-continuous, piecewise curve made of circular arcs and straioht-line segments. The paper presents an algorithm for finding an arbitrarily close arc-spline approximation to a quadratic NURBS curve. arc splines, quadratic NURBS curves

In a recent paper by Hu it is proved that for any convex function f there is a C 1 convex quadratic spline s with n knots that approximates f at the rate of | 3 ( f, n &1 ). The knots of the spline are basically equally spaced. In this paper we give a simple construction of such a spline with equall
