  2. Engineering drawing abbreviations and symbols - Wikipedia

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

    The issuance of a drawing from the engineering/design activity to the production activity. In other words, the event when a draft becomes a completed, official document. A stamp on the drawing saying "ISSUED" documents that RTP has occurred. RTV: room-temperature vulcanizing; return to vendor: 1. RTV sealants, a way to seal joints. 2.

  3. Total indicator reading - Wikipedia

    en.wikipedia.org/wiki/Total_indicator_reading

    Whereas dial test indicators will give a foreshortened reading if their tips are on an angle to the surface being measured (cosine error), a drawing callout of FIM is defined as referring to the distance traveled by the extremity of the tip—not by the lesser amount that its lever-like action moves the needle.

  4. Geometric dimensioning and tolerancing - Wikipedia

    en.wikipedia.org/wiki/Geometric_dimensioning_and...

    Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.

  5. Line drawing algorithm - Wikipedia

    en.wikipedia.org/wiki/Line_drawing_algorithm

    A simple way to parallelize single-color line rasterization is to let multiple line-drawing algorithms draw offset pixels of a certain distance from each other. [2] Another method involves dividing the line into multiple sections of approximately equal length, which are then assigned to different processors for rasterization. The main problem ...

  6. Equipollence (geometry) - Wikipedia

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

    [2] On a great circle of a sphere, two directed circular arcs are equipollent when they agree in direction and arc length. An equivalence class of such arcs is associated with a quaternion versor ⁡ = ⁡ + ⁡, where a is arc length and r determines the plane of the great circle by perpendicularity.

    A teenage hunter allegedly shot dead his parents and younger brother before taking his own life in a horrifying murder-suicide. Clifford Hunt Jr., 19, is believed to have shot parents Michelle, 48 ...

  8. Force-directed graph drawing - Wikipedia

    en.wikipedia.org/wiki/Force-directed_graph_drawing

    Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...
