EPI-HYPOCYCLOIDS AND EPI-HYPOCYCLOIDAL CANAL SURFACES
Structural Mechanics of Engineering Constructions and Buildings, 2018 In the article are regarded the curves - epiand hypocycloids, which are formed by the moving of the generating points, linked with the circles of the same radius and which are at the same time outside and inside of the unmoving circle. There is shown the relation of those curves.

Blends of canal surfaces from polyhedral medial transform representations
Computer-Aided Design, 2011 We present a new method for constructing [Formula: see text] blending surfaces between an arbitrary number of canal surfaces. The topological relation of the canal surfaces is specified via a convex polyhedron and the design technique is based on a generalization of the medial surface transform. The resulting blend surface consists of trimmed envelopes

Willmore canal surfaces in Euclidean space
, 1999 The authors give a classification of Willmore canal surfaces, that is, of surfaces that envelope a \(1\)-parameter family of spheres while extremizing the Willmore functional \(\int(H^2-K) dA\). As a key step in their classification the authors show that a Willmore canal surface is isothermic: as a consequence any Willmore canal surface has to be ...

A CANAL SURFACE CONTAINING FOUR STRAIGHT LINES
Journal of Industrial Design and Engineering GraphicsA canal surface is the envelope of spheres with centers traversing a spatial curve called spine curve. The spheres contact the envelope along so-called characteristics, which are circles in general.

Geometric characterizations of canal surfaces with Frenet center curves
AIMS Mathematics, 2021 In this work, we study the canal surfaces foliated by pseudo hyperbolic spheres $ \mathbb{H}_{0}^{2} $ along a Frenet curve in terms of their Gauss maps in Minkowski 3-space.

Classifications of Canal Surfaces with the Gauss Maps in Minkowski 3-Space
Mathematics, 2020 In this work, we study the canal surfaces foliated by pseudo spheres S12 along a Frenet curve in terms of their Gauss maps in Minkowski 3-space. Such kind of surfaces with pointwise 1-type Gauss maps are classified completely.
