MEASURING IN IMAGES WITH PROJECTIVE GEOMETRY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
There is a fundamental relationship between projective geometry and the perspective imaging geometry of a pinhole camera. Projective scales have been used to measure within images from the beginnings of photogrammetry, mostly the cross-ratio on a ...

Plane section of cone and cylinder in computer geometry [PDF]

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering, 2005
In this paper a mathematical apparatus for determination of plane section of cone and cylinder was formed. By using the descriptive geometric approach the contour lines of these quadrics were determined.

Hyperbolic plane geometry revisited [PDF]

open access: yes, 2014
Using the method of C. V\"or\"os, we establish results in hyperbolic plane geometry, related to triangles and circles. We present a model independent construction for Malfatti's problem and several trigonometric formulas for triangles.Comment: 21 pages 6

The Noncommutative Geometry of the Quantum Projective Plane [PDF]

open access: yes, 2007
We study the spectral geometry of the quantum projective plane CP^2_q, a deformation of the complex projective plane CP^2, the simplest example of a spin^c manifold which is not spin.

Geometry of Curves with Fractional Derivatives in Lorentz Plane

open access: yesJournal of New Theory, 2022
In this paper, the geometry of curves is discussed based on the Caputo fractional derivative in the Lorentz plane. Firstly, the tangent vector of a spacelike plane curve is defined in terms of the fractional derivative.

Reaction plane alignment with linearly polarized photon in heavy-ion collisions

open access: yesPhysical Review Research, 2022
The collective observables play critical roles in probing the properties of quark-gluon-plasma created in relativistic heavy-ion collisions, in which the information on initial collision geometry is crucial. However, the initial collision geometry, e.g.,
