  2. Midpoint circle algorithm - Wikipedia

    en.wikipedia.org/wiki/Midpoint_circle_algorithm

    A circle of radius 23 drawn by the Bresenham algorithm. In computer graphics, the midpoint circle algorithm is an algorithm used to determine the points needed for rasterizing a circle. It is a generalization of Bresenham's line algorithm. The algorithm can be further generalized to conic sections. [1] [2] [3]

  3. Dividing a circle into areas - Wikipedia

    en.wikipedia.org/wiki/Dividing_a_circle_into_areas

    The number of points (n), chords (c) and regions (r G) for first 6 terms of Moser's circle problem. In geometry, the problem of dividing a circle into areas by means of an inscribed polygon with n sides in such a way as to maximise the number of areas created by the edges and diagonals, sometimes called Moser's circle problem (named after Leo Moser), has a solution by an inductive method.

  4. Bricx Command Center - Wikipedia

    en.wikipedia.org/wiki/Bricx_Command_Center

    Bricx Command Center (BricxCC) is the integrated development environment (IDE) of Next Byte Codes (NBC), Not Quite C (NQC) and Not eXactly C (NXC). These programming languages are used to program the Robots in the Lego Mindstorms series. Not Quite C and Not eXactly C have a syntax like C.

  5. Concentric objects - Wikipedia

    en.wikipedia.org/wiki/Concentric_objects

    Geometric objects with a well-defined axis include circles (any line through the center), spheres, cylinders, [2] conic sections, and surfaces of revolution. Concentric objects are often part of the broad category of whorled patterns , which also includes spirals (a curve which emanates from a point, moving farther away as it revolves around ...

  6. Circle packing in a circle - Wikipedia

    en.wikipedia.org/wiki/Circle_packing_in_a_circle

    Circle packing in a circle is a two-dimensional packing problem with the objective of packing unit circles into the smallest possible ... solutions for n = 2, 3, 4, 7

  7. Director circle - Wikipedia

    en.wikipedia.org/wiki/Director_circle

    More generally, for any collection of points P i, weights w i, and constant C, one can define a circle as the locus of points X such that (,) =.. The director circle of an ellipse is a special case of this more general construction with two points P 1 and P 2 at the foci of the ellipse, weights w 1 = w 2 = 1, and C equal to the square of the major axis of the ellipse.

  8. Apollonian circles - Wikipedia

    en.wikipedia.org/wiki/Apollonian_circles

    Every blue circle intersects every red circle at a right angle. Every red circle passes through the two points C, D, and every blue circle separates the two points. In geometry, Apollonian circles are two families of circles such that every circle in the first family intersects every circle in the second family orthogonally, and vice versa.

  9. Centre (geometry) - Wikipedia

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

    In geometry, a centre (British English) or center (American English) (from Ancient Greek κέντρον (kéntron) 'pointy object') of an object is a point in some sense in the middle of the object. According to the specific definition of centre taken into consideration, an object might have no centre.
