Invariant-geometry conditions for the rational bi-quadratic Bézier surfaces
journal contribution
posted on 2014-05-28, 09:22 authored by Helmut BezA generalization of Patterson’s work (Patterson, 1985), on the invariants of the
rational Bézier curves, to the case of surfaces is presented. An equation for the
determination of the invariants for surfaces of degree (n, n) is derived and solved for
the bi-quadratics – for which it is shown that seven independent, invariant functions
exist. Explicit forms of the invariants are derived and a number of applications are
presented.
