Interpolation with piecewise quadratic visually C2 Bézier polynomials

چکیده
For data satisfying certain generalized convexity conditions, the existence and uniqueness of a piecewise quadratic curvature continuous parametric spline interpolant in IR 2 is proved. Convexity is preserved by the interpolation, and the numerical construction of the interpolant can be carried out eeciently. The interpolation is 4{th order accurate, and a number of examples shows both the applicability and the limitations of this interpolation scheme.

A multivariate Powell-Sabin interpolant
We consider the problem of constructing a C1 piecewise quadratic interpolant, Q, to positional and gradient data defined at the vertices of a tessellation of n-simplices in IR. The key to the interpolation scheme is to appropriately subdivide each simplex to ensure that certain necessary geometric constraints are satisfied by the subdivision points. We establish these constraints using the Bern...
متن کاملBivariate C1 Quadratic Finite Elements and Vertex Splines
Following work of Heindl and of Powell and Sabin, each triangle of an arbitrary (regular) triangulation A of a polygonal region ii in R is subdivided into twelve triangles, using the three medians, yielding the refinement A of A , so that C quadratic finite elements can be constructed. In this paper, we derive the Bézier nets of these elements in terms of the parameters that describe function a...

Fuzzy Hermite interpolation of 5th degree generalizes Lagrange interpolation by fitting a polynomial to a function f that not only interpolates f at each knot but also interpolates two number of consecutive Generalized Hukuhara derivatives of f at each knot. The provided solution for the 5th degree fuzzy Hermite interpolation problem in this paper is based on cardinal basis functions linear com...
متن کاملDifferentiable piecewise-Bézier interpolation on Riemannian manifolds
We propose a generalization of classical Euclidean piecewiseBézier surfaces to manifolds, and we use this generalization to compute a C1-surface interpolating a given set of manifold-valued data points associated to a regular 2D grid. We then propose an efficient algorithm to compute the control points defining the surface based on the Euclidean concept of natural C2-splines and show examples o...
متن کاملQuasi-interpolation by quadratic piecewise polynomials in three variables
A quasi-interpolation method for quadratic piecewise polynomials in three variables is described which can be used for the efficient visualization of gridded volume data. We analyze the smoothness properties of the trivariate splines. We prove that the splines yield nearly optimal approximation order while simultaneously its piecewise derivatives provide optimal approximation of the derivatives...
