  2. 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.

  3. GIMP - Wikipedia

    en.wikipedia.org/wiki/GIMP

    GIMP's native format XCF is designed to store all information GIMP can contain about an image; XCF is named after the eXperimental Computing Facility where GIMP was authored. Import and export capability can be extended to additional file formats by means of plug-ins. XCF file size is extended to more than 4 GB since 2.9.6 and new stable tree 2 ...

  4. Circular motion - Wikipedia

    en.wikipedia.org/wiki/Circular_motion

    In non-uniform circular motion, an object moves in a circular path with varying speed. Since the speed is changing, there is tangential acceleration in addition to normal acceleration. The net acceleration is directed towards the interior of the circle (but does not pass through its center).

  5. XCF (file format) - Wikipedia

    en.wikipedia.org/wiki/XCF_(file_format)

    XCF, short for eXperimental Computing Facility, [1] is the native image format of the GIMP image-editing program. It saves all of the data the program handles related to the image, including, among others, each layer, the current selection, channels, transparency, paths and guides.

  6. Centripetal force - Wikipedia

    en.wikipedia.org/wiki/Centripetal_force

    One common example involving centripetal force is the case in which a body moves with uniform speed along a circular path. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. [3] [4] The mathematical description was derived in 1659 by the Dutch physicist Christiaan ...

    Select everything (Ctrl-A) and choose the Path>Stroke to Path command. In the File>Save As.. dialog look for the drop-down menu just above the Save button and save as a Plain SVG . If that doesn't work, call your local friendly WikiGraphist at Wikipedia:Graphic Lab/Images to improve or Wikipedia talk:WikiProject Maps .

  8. Inversive geometry - Wikipedia

    en.wikipedia.org/wiki/Inversive_geometry

    P ' is the inverse of P with respect to the circle. To invert a number in arithmetic usually means to take its reciprocal. A closely related idea in geometry is that of "inverting" a point. In the plane, the inverse of a point P with respect to a reference circle (Ø) with center O and radius r is a point P ', lying on the ray from O through P ...

  9. Path (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Path_(graph_theory)

    A three-dimensional hypercube graph showing a Hamiltonian path in red, and a longest induced path in bold black. In graph theory, a path in a graph is a finite or infinite sequence of edges which joins a sequence of vertices which, by most definitions, are all distinct (and since the vertices are distinct, so are the edges).
