Numerical proper reparametrization of parametric plane curves
نویسندگان
چکیده
Proper reparametrization is a basic simplifying process for rational parameterized curves. There are complete results proposed for the curves with exact coefficients but few papers discuss the situations with numerical coefficients which have many practical applications. In this paper, we deal with mathematical objects that are assumed to be given approximately. The approximate improper index is firstly defined. Then, we provide some important properties concerning the approximate improper index and the numerical reparametrization. Finally, we propose the numerical reparametrization algorithm for rational parametric plane curves, and the error bound is carefully discussed.

Reparametrization of NURBS Curves
In geometric design, it is often useful to be able to give an arc length reparametrization for NURBS curves, that keeps the curve a NURBS too. Since parametric rational curves, except for straight lines, cannot be parametrized by arc length, we developed a numerical method of approximating the arc length parametrization function. In this way it was possible to obtain a good parametrization of a...
متن کاملHigh order interpolation of curves in the plane
We consider high order representations of curves in the plane. Through a series of complementary numerical examples, we show that classical interpolation is sometimes far from optimal in the sense of minimizing the interpolation error using a fixed number of degrees-of-freedom (the Kolmogorov n-width problem). We propose a new way of constructing a high order interpolant of a curve in the plane...
متن کاملKnot Insertion and Reparametrization of Interval B-spline Curves
Knot insertion is the operation of obtaining a new representation of a B-spline curve by introducing additional knot values to the defining knot vector. The new curve has control points consisting of the original control points and additional new control points corresponding to the number of new knot values. So knot insertions give additional control points which provide extra shape control wit...
متن کاملReparametrization and Subdivision of Interval Bezier Curves
Interval Bezier curve are new representation forms of parametric curves. Using this new representation, the problem of lack of robustness in all state-of-the art CAD systems can be largely overcome. In this paper this concept has been discussed to form a new curve over rectangular domain such that its parameter varies in an arbitrary range , instead of standard parameter , -. Where and are real...
متن کاملThe Proper Parametrization of a Special Class of Rational Parametric Equations
We give a proper reparametrization theorem for a set of rational parametric equations which is proper for all but one of its parameters. We also give an algorithm to determine whether a set of rational parametric equations belongs to this class, and if it does, we reparametrize it such that the new parametric equations are proper.
