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.
Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry. A rendering algorithm only draws pixels in the intersection between the
Direct2D [1] is a 2D vector graphics application programming interface (API) designed by Microsoft and implemented in Windows 10, [2] Windows 8, Windows 7 and Windows Server 2008 R2, and also Windows Vista and Windows Server 2008 (with Platform Update installed).
DXR was released with the Windows 10 October update (version 1809) on October 10, 2018. It requires an AMD Radeon RX 6000 series , AMD Radeon RX 7000 series , Intel Arc A or B series, or Nvidia GeForce 20 , 30 , or 40 series video card , which is designed to handle the high computing load used for ray tracing.
In geometry, the Steiner inellipse, [1] midpoint inellipse, or midpoint ellipse of a triangle is the unique ellipse inscribed in the triangle and tangent to the sides at their midpoints. It is an example of an inellipse .
Caustic Graphics [20] produced a plug in card, the "CausticOne" (2009), [21] that accelerated global illumination and other ray based rendering processes when coupled to a PC CPU and GPU. The hardware is designed to organize scattered rays (typically produced by global illumination problems) into more coherent sets (lower spatial or angular ...
