Projective Reconstruction of Surfaces of Revolution [PDF]

open access: yes, 2003
This paper addresses the problem of recovering the generating curve of a surface of revolution from a single uncalibrated perspective view, based solely on the object’s outline and two (partly) visible cross-sections. Without calibration of the camera’s internal parameters such recovery is only possible up to a particular transformation of the true ...

Geodesics on surfaces of revolution [PDF]

open access: yesTransactions of the American Mathematical Society, 1946
Introduction. We are concerned in this paper with the behavior in the large of the geodesic lines on a class of surfaces of revolution. The central theme is the number and the distribution of the double points of these geodesics, and one of the main theorems establishes a "zoning" of the surfaces in a manner dictated by this distribution.

DEVELOPMENT OF SOME REVOLUTION SURFACES

open access: yesJournal of Industrial Design and Engineering Graphics, 2015
The paper work proposes practical graphic methods provided by Descriptive Geometry to plot the development of two revolution surfaces: the revolution surface having an oval as median section and the revolution surface having an ordinary curve as median ...

Surfaces of Revolution and Canal Surfaces with Generalized Cheng–Yau 1-Type Gauss Maps

open access: yesMathematics, 2020
In the present work, the notion of generalized Cheng–Yau 1-type Gauss map is proposed, which is similar to the idea of generalized 1-type Gauss maps. Based on this concept, the surfaces of revolution and the canal surfaces in the Euclidean three-space ...

Space–time slices and surfaces of revolution [PDF]

open access: yesJournal of Mathematical Physics, 2004
Under certain conditions, a (1+1)-dimensional slice ĝ of a spherically symmetric black hole space–time can be equivariantly embedded in (2+1)-dimensional Minkowski space. The embedding depends on a real parameter that corresponds physically to the surface gravity κ of the black hole horizon.

On the Gauss Map of Surfaces of Revolution with Nonlightlike Axis in Minkowski 3-Space

open access: yesAbstract and Applied Analysis, 2014
We study surfaces of revolution with a nonlightlike axis in 3-dimensional Minkowski space and classify such surfaces in terms of the Gauss map G that satisfies the condition ΔhG=ΛG, with Λ being a 3×3 real matrix.
