Apollonian de Casteljau-type algorithms for complex rational Bézier curves

. A rational curve of the complex degree n admits generically n! distinct de Casteljau-typeWe describe a new de Casteljau-type algorithm for complex rational Bezier curves. After proving that thes...

Surfaces with Pythagorean normals along rational curves

A rational curve on a rational surface such that the unit normal vector field of the surface along this curve is rational will be called a curve providing Pythagorean surface normals (or shortly a...

Medial axis transforms yielding rational envelopes

Minkowski Pythagorean hodograph (MPH) curves provide a means for representing domains with rational boundaries via the medial axis transform. Based on the observation that MPH curves are not the only curves that yi...

Symbolic Algorithm For Computing Approximate Parameterizations Over Rationals

It is well known that an irreducible algebraic curve is rational if and only to parameterize approximately affine rational plane curves by means of linear systems of adjoint curves and one chosen ratio...

Rational Pythagorean-hodograph space curves

A method for constructing rational Pythagorean-hoclograph (PH) curves in R(3 is a developable ruled surface. The rational PH space curve is identified as the edge of regression (or cuspidal edge) of this developabl...

Translation surfaces and isotropic nets on rational minimal surfaces

of rational isotropic curves with a prescribed tangent field which leads by translating one curve along another one. We focus on the geometry of translation surfaces generated by two algebraic curves in space and ...

Mapping rational rotation-minimizing frames from polynomial curves on to rational curves

Given a polynomial space curve that has a rational rotation-minimizing frame (an RRMF curve), a methodology is developed to construct families of rational space. The construction employs the dual form of a rati...

On rational Minkowski Pythagorean hodograph curves

. In the present paper we generalize this polynomial class to a rational class of curves in Minkowski 3-space. We show that any rational Minkowski Pythagorean hodograph curve can be obtained in terms of its associa...
