Optimal parametric interpolants of circular arcs

Vavpetič, Aleš (author)

The aim of this paper is a construction of quartic parametric polynomial interpolants of a circular arc, where two boundary points of a circular arc are interpolated. For every unit circular arc of an inner angle not greater than $2\pi$ we find the best interpolant, where the optimality is measured by the simplified radial error.

Abstract

V članku obravnavamo konstrukcijo kvartičnih parametričnih polinomov, ki interpolirajo krožni lok tako, da se v krajiščih krivulji ujemata. Za enotski krožni lok z notranjim kotom ne večjim od $2\pi$, konstruiramo najboljši interpolant, kjer optimalnost merimo glede na poenostavljeno radialno napako.
