Rational Bézier curves with infinitely many integral points [PDF]

open access: yes, 2023
summary:In this paper we consider rational Bézier curves with control points having rational coordinates and rational weights, and we give necessary and sufficient conditions for such a curve to have infinitely many points with integer coefficients ...

Variational design of smooth rational Bézier curves [PDF]

open access: yes, 1991
International audienceNURBS' are eurrently seen as the most promising curve form in CAO /CAM applications. Rational Bézier curves are special non-uniform rational B-splines. In this paper we describe a calculus of variation approach to design the weights

Rational Bézier Curve and Its Application in Blending of Thickness Different Tubes

open access: yes, 2018
In this paper, the rational Bézier curve can be adjusted and controlled in the shape of a curve near a particular control point. Then, on the basis of the smooth blending circular tubes with the two different radiuses, the axes of the tubes are non ...

Rational tensor product Bézier volumes [PDF]

open access: yes, 1994
Free form volumes in rational Bézier representation are derived via homogeneous coordinates. Some properties and constructions are presented and two applications of free form volumes are discussed: definition of solid primitives and curve and surface ...

New shape control tools for rational Bézier curve design

open access: yes, 2022
Bézier curves are indispensable for geometric modelling and computer graphics. They have numerous favourable properties and provide the user with intuitive tools for editing the shape of a parametric polynomial curve. Even more control and flexibility

Toric degenerations of Bézier patches [PDF]

open access: yes, 2011
The control polygon of a rational Bézier curve is well-defined and has geometric significance; there is a sequence of weights under which the limiting position of the curve is the control polygon.
