  2. Point-finite collection - Wikipedia

    en.wikipedia.org/wiki/Point-finite_collection

    In mathematics, a collection or family of subsets of a topological space is said to be point-finite if every point of lies in only finitely many members of . [1] [2]. A metacompact space is a topological space in which every open cover admits a point-finite open refinement.

  3. Well-known text representation of geometry - Wikipedia

    en.wikipedia.org/wiki/Well-known_text...

    Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable.

  4. Point (geometry) - Wikipedia

    en.wikipedia.org/wiki/Point_(geometry)

    In geometry, a point is an abstract idealization of an exact position, without size, in physical space, [1] or its generalization to other kinds of mathematical spaces.As zero-dimensional objects, points are usually taken to be the fundamental indivisible elements comprising the space, of which one-dimensional curves, two-dimensional surfaces, and higher-dimensional objects consist; conversely ...

  5. Locally finite collection - Wikipedia

    en.wikipedia.org/wiki/Locally_finite_collection

    A collection of subsets of a topological space is said to be locally finite if each point in the space has a neighbourhood that intersects only finitely many of the sets in the collection. [1] In the mathematical field of topology, local finiteness is a property of collections of subsets of a topological space.

    A point cloud is a discrete set of data points in space. The points may represent a 3D shape or object. Each point position has its set of Cartesian coordinates (X, Y ...

    Point Blank, known as Gun Bullet (ガンバレット, Gan Baretto), or Gunvari (ガンバリ, Ganbari) in Japan, is a series of light gun shooter games developed by Namco for the arcade, PlayStation and Nintendo DS; the trilogy was first released in arcade in 1994 and was later ported onto the PlayStation.

  9. Generic point - Wikipedia

    en.wikipedia.org/wiki/Generic_point

    A generic point of the topological space X is a point P whose closure is all of X, that is, a point that is dense in X. [1]The terminology arises from the case of the Zariski topology on the set of subvarieties of an algebraic set: the algebraic set is irreducible (that is, it is not the union of two proper algebraic subsets) if and only if the topological space of the subvarieties has a ...
