Stereographic projection — In geometry, the stereographic projection is a particular mapping (function) that projects a sphere onto a plane. The projection is defined on the entire sphere, except at one point mdash; the projection point. Where it is defined, the mapping is … Wikipedia
Pole figure — A pole figure is a graphical representation of the orientation of objects in space. For example, pole figures in the form of stereographic projections are used to represent the orientation distribution of crystallographic lattice planes in… … Wikipedia
stereographic projection — Perspective projections in which a graticule of reduced earth is projected onto a plane tangential to reduced earth at a point from a point diametrically opposite to the point of tangency. In such a projection, the meridians and parallels are… … Aviation dictionary
stereographic projection — Math. a one to one correspondence between the points on a sphere and the extended complex plane where the north pole on the sphere corresponds to the point at infinity of the plane. Cf. extended complex plane. [1695 1705] * * * … Universalium
Universal Polar Stereographic coordinate system — The Universal Polar Stereographic (UPS) coordinate system is used in conjunction with the Universal Transverse Mercator (UTM) coordinate system to locate positions on the surface of the earth. Like the UTM coordinate system, the UPS coordinate… … Wikipedia
polar stereographic projection — A projection formed by positioning a flat sheet of paper tangential over one pole on the reduced earth and projecting the latitude and longitude graticule onto the paper from a light source positioned at the other pole. In this projection, the… … Aviation dictionary
universal polar stereographic grid — A military grid system for use in limited areas in operations requiring precise position reporting. It covers areas between the 80° latitude and the poles. The northern pole area is divided into two parts by the 180° meridian. The western half is … Aviation dictionary
3-sphere — Stereographic projection of the hypersphere s parallels (red), meridians (blue) and hypermeridians (green). Because this projection is conformal, the curves intersect each other orthogonally (in the yellow points) as in 4D. All curves are circles … Wikipedia
Möbius transformation — Not to be confused with Möbius transform or Möbius function. In geometry, a Möbius transformation of the plane is a rational function of the form of one complex variable z; here the coefficients a, b, c, d are complex numbers satisfying ad − … Wikipedia
Complex plane — Geometric representation of z and its conjugate in the complex plane. The distance along the light blue line from the origin to the point z is the modulus or absolute value of z. The angle φ is the argument of z. In mathematics … Wikipedia
