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]
An extension to the original algorithm called the midpoint circle algorithm may be used for drawing circles. While algorithms such as Wu's algorithm are also frequently used in modern computer graphics because they can support antialiasing , Bresenham's line algorithm is still important because of its speed and simplicity.
Bresenham's line algorithm, developed in 1962, is his most well-known innovation. It determines which points on a 2-dimensional raster should be plotted in order to form a straight line between two given points, and is commonly used to draw lines on a computer screen.
Much more compact way of drawing grid: 16:56, 13 September 2009: 282 × 282 (21 KB) ... Midpoint circle algorithm (also known as Bresenham's circle algorithm).
Wu's algorithm is comparatively fast, but is still slower than Bresenham's algorithm. The algorithm consists of drawing pairs of pixels straddling the line, each coloured according to its distance from the line. Pixels at the line ends are handled separately. Lines less than one pixel long are handled as a special case. An extension to the ...

2. In my opinion the animated image that is a screen capture of someone's unique implementation of Bresenham's line algorithm is unhelpful. 3. The method to generalize the algorithm to all 8 octants can be simplified and presented more clearly. 72.229.111.192 20:30, 24 May 2017 (UTC) Regarding point 1: It's still wrong.
