  2. Layer Pyramid - Wikipedia

    en.wikipedia.org/wiki/Layer_Pyramid

    The layer pyramid exhibits at one site both complex developments concerning its substructures and simplifications concerning the building methods employed for the superstructure. According to these egyptologists, the layer pyramid is a clearly advanced version of the buried pyramid of Sekhemkhet. [4] [5] [10]

  3. Pyramid (image processing) - Wikipedia

    en.wikipedia.org/wiki/Pyramid_(image_processing)

    Pyramid, or pyramid representation, is a type of multi-scale signal representation developed by the computer vision, image processing and signal processing communities, in which a signal or an image is subject to repeated smoothing and subsampling. Pyramid representation is a predecessor to scale-space representation and multiresolution analysis.

  4. C4 model - Wikipedia

    en.wikipedia.org/wiki/C4_model

    The C4 model was created by the software architect Simon Brown between 2006 and 2011 on the roots of Unified Modelling Language (UML) and the 4+1 architectural view model. The launch of an official website under a Creative Commons license [3] and an article [4] published in 2018 popularised the emerging technique. [1]

  5. Types of mesh - Wikipedia

    en.wikipedia.org/wiki/Types_of_mesh

    The possible element choices are quadrilateral in 2D and hexahedra in 3D. This model is highly space efficient, since the neighbourhood relationships are defined by storage arrangement. Some other advantages of structured grid over unstructured are better convergence and higher resolution. [3] [4] [5]

  6. Tesseract - Wikipedia

    en.wikipedia.org/wiki/Tesseract

    In geometry, a tesseract or 4-cube is a four-dimensional hypercube, analogous to a two-dimensional square and a three-dimensional cube. [1] Just as the perimeter of the square consists of four edges and the surface of the cube consists of six square faces, the hypersurface of the tesseract consists of eight cubical cells, meeting at right angles.

  7. Zawyet El Aryan - Wikipedia

    The Layer Pyramid was built in the Third Dynasty, probably during the reign of Khaba. The pyramid was meant to be a step pyramid of possibly five to seven steps. No casing stones have been found, suggesting that the pyramid was never finished. The layout of the underground chambers resembles that of the Buried Pyramid. A corridor leading into ...

  8. 5-cell - Wikipedia

    en.wikipedia.org/wiki/5-cell

    In geometry, the 5-cell is the convex 4-polytope with Schläfli symbol {3,3,3}. It is a 5-vertex four-dimensional object bounded by five tetrahedral cells. It is also known as a C 5, hypertetrahedron, pentachoron, [1] pentatope, pentahedroid, [2] tetrahedral pyramid, or 4-simplex (Coxeter's polytope), [3] the simplest possible convex 4-polytope, and is analogous to the tetrahedron in three ...

  9. Duopyramid - Wikipedia

    en.wikipedia.org/wiki/Duopyramid

    The lowest dimensional forms are 4 dimensional and connect two polygons. A p-q duopyramid or p-q fusil, represented by a composite Schläfli symbol {p} + {q}, and Coxeter-Dynkin diagram. The regular 16-cell can be seen as a 4-4 duopyramid or 4-4 fusil, , symmetry [[4,2,4]], order 128. A p-q duopyramid or p-q fusil has Coxeter group symmetry [p ...
