  2. Build the Earth - Wikipedia

    en.wikipedia.org/wiki/Build_the_Earth

    Minecraft developer Mojang Studios featured the project on their website on Earth Day 2020. [7] In July 2020, YouTuber MrBeast released a video where he and 50 other people built his hometown of Raleigh, North Carolina within the project. [8] In 2020, a full sized recreation of the Taj Mahal was completed on the server by Daniel Tan. [9]

  3. Earth-centered, Earth-fixed coordinate system - Wikipedia

    en.wikipedia.org/wiki/Earth-centered,_Earth...

    The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.

  4. Plücker coordinates - Wikipedia

    en.wikipedia.org/wiki/Plücker_coordinates

    Each Plücker coordinate appears in two of the four equations, each time multiplying a different variable; and as at least one of the coordinates is nonzero, we are guaranteed non-vacuous equations for two distinct planes intersecting in L. Thus the Plücker coordinates of a line determine that line uniquely, and the map α is an injection.

  5. Geohash - Wikipedia

    en.wikipedia.org/wiki/Geohash

    Since a geohash (in this implementation) is based on coordinates of longitude and latitude the distance between two geohashes reflects the distance in latitude/longitude coordinates between two points, which does not translate to actual distance, see Haversine formula. Example of non-linearity for latitude-longitude system:

  6. Quaternions and spatial rotation - Wikipedia

    3D visualization of a sphere and a rotation about an Euler axis (^) by an angle of In 3-dimensional space, according to Euler's rotation theorem, any rotation or sequence of rotations of a rigid body or coordinate system about a fixed point is equivalent to a single rotation by a given angle about a fixed axis (called the Euler axis) that runs through the fixed point. [6]

  7. Geographical distance - Wikipedia

    en.wikipedia.org/wiki/Geographical_distance

    View from the Swabian Jura to the Alps. Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length.. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.

  8. Curvilinear coordinates - Wikipedia

    en.wikipedia.org/wiki/Curvilinear_coordinates

    A Cartesian coordinate surface in this space is a coordinate plane; for example z = 0 defines the x-y plane. In the same space, the coordinate surface r = 1 in spherical coordinates is the surface of a unit sphere, which is curved. The formalism of curvilinear coordinates provides a unified and general description of the standard coordinate ...

  9. Mipmap - Wikipedia

    en.wikipedia.org/wiki/Mipmap

    In computer graphics, mipmaps (also MIP maps) or pyramids [1] [2] [3] are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the previous.
