An analysis of cubic approximation schemes for conic sections
نویسنده
چکیده
In this paper a piece of a conic section is approximated by a cubic or piecewise cubic polynomial. The main tool is to define the two inner control points of the cubic as an affine combination, defined by λ ∈ [0, 1], of two control points of the conic. If λ is taken to depend on the weight w of the latter, a function λ(w) results which is used to distinguish between different algorithms and to analyze their properties. One of the approximations is a piecewise cubic having G continuity at the break points. §

متن کاملA Highly Accurate Approximation of Conic Sections by Quartic Bézier Curves
A new approximation method for conic section by quartic Bézier curves is proposed. This method is based on the quartic Bézier approximation of circular arcs. We give the upper bound of Hausdorff distance between the conic section and the quartic Bézier curve, and also show that the approximation order is eight. And we prove that our approximation method has a smaller upper bound than previous q...
متن کاملAn O(h2n) Hermite approximation for conic sections
Given a segment of a conic section in the form of a rational quadratic Bézier curve and any positive odd integer n, a geometric Hermite interpolant, with 2n contacts, counting multiplicity, is presented. This leads to a G spline approximation having an approximation order of O(h). A bound on the Hausdorff error of the Hermite interpolant is provided. Both the interpolation and error bound are e...

متن کاملAnalyzing the Optical Properties and Peak Behavior Due to Plasmon Resonance of Silver Cubic-Shape Nanostructures by Means of Discrete Dipole Approximation
In this article, the optical properties of silver cubic-shape nanostructures (SCNs) were analyzed by employing the discrete dipole approximation (DDA) in aqueous media. The absorption, dispersion and extinction cross-sections of these nanostructures were calculated based on the wavelength change of the incident light in the visible and near infrared region. Moreover, the height change, waveleng...
