In their classic treatment (5) Veblen and Young build n-dimensional projective geometry from points and lines. Naturally, each line becomes identified with the set of points with which it is incident, and many treatments build from points alone, postulating the existence of certain distinguished subsets of the set of points.

Geometry based exhaustive line correspondence determination
2016 IEEE International Conference on Robotics and Automation (ICRA), 2016In this paper we propose a purely geometric approach to establish correspondence between 3D line segments in a given model and 2D line segments detected in an image. Contrary to the existing methods which use strong assumptions on camera pose, we perform exhaustive search in order to compute maximum number of geometrically permitted correspondences ...

The geometry of lines occurs naturally in such different areas as sculptured surface machining, computation of offsets and medial axes, surface reconstruction for reverse engineering, geometrical optics, kinematics and motion design, and modeling of developable surfaces.

Spinor Space and Line Geometry
Canadian Journal of Mathematics, 1951Synopsis. This is the first of two papers dealing with the projective theory of spinors. It contains the algebraic introduction to the projective spinor analysis which will be dealt with in the second paper.

Kinematic Registration Using Line Geometry
Volume 2: 28th Biennial Mechanisms and Robotics Conference, Parts A and B, 2004This paper uses line geometry to find an elegant solution to the kinematic registration problem involving reconstruction of a spatial displacement from data on three homologous points at two finitely separated positions of a rigid body. The bisecting linear line complex of two position theory in kinematics is used in combination with recent results ...

Point-line geometries are just rank two geometries, and so inherit the concepts of morphism and cover from the last chapter. The symmetry between the two types is broken by the concept of a subspace, which treats points differently from lines. A new graph, the point-collinearity graph, is useful in describing geometric properties.

Fuzzy plane geometry I: Points and lines
Fuzzy Sets and Systems, 1997This paper initiates the study of fuzzy geometry by first studying two basic ideas, fuzzy points and fuzzy lines, in fuzzy plane geometry. The authors consider the fuzzy distance between fuzzy points and show that it is a weak fuzzy metric. They study various definitions of a fuzzy line, develop their basic properties, and investigate parallel fuzzy ...

The Geometry of Decoupled Line Driven Winds
Astrophysics and Space Science, 1995Bjorkman & Cassinelli (1993) have proposed a mechanism that is expected to produce strong equatorial focusing of the radiation-driven winds from rapidly-rotating B stars. Here the possibility of the decoupling of the stellar radiation field and the outflow is considered.
