An extension algorithm for B-splines by curve unclamping
نویسندگان
چکیده
This paper presents an algorithm for extending B-spline curves and surfaces. Based on the unclamping algorithm for B-spline curves, we propose a new algorithm for extending B-spline curves that extrapolates using the recurrence property of the de Boor algorithm. This algorithm provides a nice extension, with maximum continuity, to the original curve segment. Moreover, it can be applied to the extension of B-spline surfaces. Extension to both single and multiple target points/curves are considered in this paper. q 2002 Elsevier Science Ltd. All rights reserved.

Euler arc splines for curve completion
This paper introduces a special arc spline called an Euler arc spline as the basic form for visually pleasing completion curves. It is considered as an extension of an Euler curve in the sense that the points in the Euler curve are replaced by arcs. A simple way for specifying it, which is suitable for shape completion, is presented. It is shown that Euler arc splines have several properties de...
متن کاملMoments of Dirichlet Splines and Their Applications to Hypergeometric Functions
Dirichlet averages of multivariate functions are employed for a derivation of basic recurrence formulas for the moments of multivariate Dirichlet splines. An algorithm for computing the moments of multivariate simplex splines is presented. Applications to hypergeometric functions of several variables are discussed. Introduction. In [9], H.B. Curry and I.J. Schoenberg have pointed out that univa...
متن کاملCurve fitting with arc splines for NC toolpath generation
Arc splines are important in automatically controlled complex curve cutting process. However, the problem of how to determine the parameter of arcs according to desired curve fitting accuracy has not been completely solved. This paper presents a new algorithm for finding arbitrarily close bi-arc splines. It is based on research on the characteristics of spiral curves. The algorithm has several ...
متن کاملB ( asic ) - Spline Basics
This essay reviews those basic facts about (univariate) B-splines that are of interest in CAGD. The intent is to give a self-contained and complete development of the material in as simple and direct a way as possible. For this reason, the B-splines are defined via the recurrence relations, thus avoiding the discussion of divided differences which the traditional definition of a B-spline as a d...
متن کاملA FILTERED B-SPLINE MODEL OF SCANNED DIGITAL IMAGES
We present an approach for modeling and filtering digitally scanned images. The digital contour of an image is segmented to identify the linear segments, the nonlinear segments and critical corners. The nonlinear segments are modeled by B-splines. To remove the contour noise, we propose a weighted least q m s model to account for both the fitness of the splines as well as their approximate cur...
