Recognizing implicitly given rational canal surfaces
It is still a challenging task of today to recognize the type of a given algebraic surface which is described only by its implicit representation. In this paper we will investigate in more detail the case of canal surfaces that are often used in geometric modelling, Computer-Aided Design and technical practice (e.g. as blending surfaces smoothly joining two parts with circular ends). It is know...
متن کاملApproximate Rational Parameterization of Implicitly Defined Surfaces
We present a method for approximate rational parameterization of algebraic surfaces of arbitrary degree and genus (or more general implicitly defined surfaces), based on numerical optimization techniques. The method computes patches of maximal size on these surfaces subject to certain quality constraints. It can be used to generate local low degree approximations and rational approximations of ...
متن کاملComputing Rational Parametrizations of Canal Surfaces
Current CAD systems can represent curves and surfaces only in rational B-spline (NURBS) form ( .Farin, 1994; .Hoschek and Lasser, 1993). On the other hand, certain curves and surfaces that arise in practical applications such as offsets of rational curves or surfaces are in general not rational and therefore need to be approximated. This motivated .Farouki and Sakkalis (1990) to introduce the s...
متن کاملOn the Parameterization of Rational Ringed Surfaces and Rational Canal Surfaces
Ringed surfaces and canal surfaces are surfaces that contain a one-parameter family of circles. Ringed surfaces can be described by a radius function, a directrix curve and vector field along the directrix curve, which specifies the normals of the planes that contain the circles. In particular, the class of ringed surfaces includes canal surfaces, which can be obtained as the envelopes of a one...
متن کاملAlmost rotation-minimizing rational parametrization of canal surfaces
Almost rotation minimizing parametrization of the canal surface is given. The basic building block of our approach is the curve approximation scheme that enables us to construct a curve, called the parameter curve, on the canal surface that produces, when projected and rescaled, an almost parallel normal vector field on the spine curve. Its construction relies on our earlier methods and results...
