Practical C1 Reparametrization of Piecewise Rational Bézier Curves
نویسندگان
چکیده
Piecewise rational Bézier curves with G-continuity in the projective space provide a useful tool for shape blending applications with complex boundary conditions where visual continuity is required. This paper presents an efficient method to construct such curves given an initial sequence of rational segments Gcontinuous in the affine space. Combination of degree elevation and linear rational reparametrization is used to transform the curve in the projective space.

An Optimal G^2-Hermite Interpolation by Rational Cubic Bézier Curves
In this paper, we study a geometric G^2 Hermite interpolation by planar rational cubic Bézier curves. Two data points, two tangent vectors and two signed curvatures interpolated per each rational segment. We give the necessary and the sufficient intrinsic geometric conditions for two C^2 parametric curves to be connected with G2 continuity. Locally, the free parameters w...
متن کاملArc Length of Rational Bézier Curves and Use for CAD Reparametrization
The length Λ of a given rational Bézier curve is efficiently estimated. Since a rational Bézier function is nonlinear, it is usually impossible to evaluate its length exactly. The length is approximated by using subdivision and the accuracy of the approximation Λn is investigated. In order to improve the efficiency, adaptivity is used with some length estimator. A rigorous theoretical analysis ...
متن کاملModélisation géométrique de surfaces lisses: Design et Fairing. (Geometric modeling of smooth surfaces: Design and Fairing)
A piecewise quintic G1 spline surface interpolating the vertices of a triangular surface mesh of arbitrary topological type is presented. The surface has an explicit triangular Bézier representation, is affine invariant and has local support. The twist compatibility problem which arises when joining an even number of polynomial patches G1 continuously around a common vertex is solved by constru...
متن کاملOn the Geometry and the Deformation of Shapes Represented by Piecewise Continuous Bézier Curves with Application to Shape Optimization
In this work, we develop a framework based on piecewise Bézier curves to plane shapes deformation and we apply it to shape optimization problems. We describe a general setting and some general result to reduce the study of a shape optimization problem to a finite dimensional problem of integration of a special type of vector field. We show a practical problem where this approach leads to effici...
متن کاملNumerical proper reparametrization of parametric plane curves
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 i...
