  2. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    model-based definition: Definition of the part via a 3D CAD model rather than via a 2D engineering drawing. Drawings may be printed (plotted) from the model for reference use, but the model remains the governing legal instrument. MBP: measurement between pins: threads, splines, gears (internal, female) (synonymous with MBW) (see also MOP, MOW) MBW

  3. 3D Face Morphable Model - Wikipedia

    en.wikipedia.org/wiki/3D_Face_Morphable_Model

    Their work is the first to introduce a statistical model for faces that enabled 3D reconstruction from 2D images and a parametric face space for controlled manipulation. [ 2 ] In the original definition of Blanz and Vetter, [ 1 ] the shape of a face is represented as the vector S = ( X 1 , Y 1 , Z 1 , . . .

  4. Wavefront .obj file - Wikipedia

    en.wikipedia.org/wiki/Wavefront_.obj_file

    The file format is open and has been adopted by other 3D graphics application vendors. The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex , the UV position of each texture coordinate vertex, vertex normals , and the faces that make each polygon defined as a list of vertices, and ...

  5. Sun (heraldry) - Wikipedia

    en.wikipedia.org/wiki/Sun_(heraldry)

    The most usual form, often called sun in splendour or in his glory, consists of a round disc with the features of a human face surrounded by twelve or sixteen rays alternating wavy and straight. [ 2 ] [ 3 ] The alternating straight and wavy rays are often said to represent the light and heat of the sun respectively.

  6. Façade - Wikipedia

    en.wikipedia.org/wiki/Façade

    A façade or facade (/ f ə ˈ s ɑː d / ⓘ; [1]) is generally the front part or exterior of a building. It is a loanword from the French façade (pronounced), which means "frontage" or "face". In architecture, the façade of a building is often the most important aspect from a design standpoint, as it sets the tone for the rest of the building.

  7. Face (geometry) - Wikipedia

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

    In elementary geometry, a face is a polygon [note 1] on the boundary of a polyhedron. [3] [4] Other names for a polygonal face include polyhedron side and Euclidean plane tile. For example, any of the six squares that bound a cube is a face of the cube. Sometimes "face" is also used to refer to the 2-dimensional features of a 4-polytope.

  8. Tower of the Sun - Wikipedia

    en.wikipedia.org/wiki/Tower_of_the_Sun

    A face between two arms represents the present, and a black face on the rear of the tower is the sun of the past. Originally another face, "Sun of the Underworld" was located on the basement floor, yet currently it has been moved to an unknown location. The jagged red paintings on the front of the tower represent thunder.

  9. Back-face culling - Wikipedia

    en.wikipedia.org/wiki/Back-face_culling

    On the left a model without BFC; on the right the same model with BFC: back-faces are removed. In computer graphics, back-face culling determines whether a polygon is drawn. It is a step in the graphical pipeline that tests whether the points in the polygon appear in clockwise or counter-clockwise order when projected onto the screen.
