Reconstruction of Surfaces of Revolution

First International Multi-Symposiums on Computer and Computational Sciences (IMSCCS'06), 2006
In the process of reconstruction of 3D textured models of revolution from images, the precise 3D shape of the revolution must be obtained in advance. This paper addresses the problem of recovering the 3D shape of revolution by symmetry property of revolution.

Determine When a Parametric Surface is a Surface of Revolution

International Electronic Journal of Geometry, 2022
A surface of revolution is a surface that can be generated by rotating a planar curve (the directrix) around a straight line (the axis) in the same plane. Using the mathematics of quaternions, we provide a parametric equation of a surface of revolution generated by rotating a directrix about an axis by quaternion multiplication of the parametric ...

The Steiner Problem on Surfaces of Revolution

Graphs and Combinatorics, 2012
The Steiner problem consists on finding the shortest path network connecting a finite set of given points on a surface. It is well understood in the Euclidean plane and on surfaces of constant curvature. The aim of the paper is to develop an algorithm for the \(n\)-point Steiner problem on a surface of revolution with a non-decreasing generating ...

Finding the Axis of Revolution of an Algebraic Surface of Revolution

IEEE Transactions on Visualization and Computer Graphics, 2016
We present an algorithm for extracting the axis of revolution from the implicit equation of an algebraic surface of revolution based on three distinct computational methods: factoring the highest order form into quadrics, contracting the tensor of the highest order form, and using univariate resultants and gcds.

Offsetting Revolution Surfaces

2011
In this paper, first, we provide a resultant-based implicitization method for revolution surfaces, generated by non necessarily rational curves. Secondly, we analyze the offsetting problem for revolution surfaces, proving that the offsetting and the revolution constructions are commutative.

A subdivision scheme for surfaces of revolution

Computer Aided Geometric Design, 2001
This paper describes a simple and efficient non-stationary subdivision scheme of order \(4.\) This curve scheme unifies known subdivision rules for cubic B-splines, splines-in-tension and a certain class of trigonometric splines capable of reproducing circles.
