We may approximate a circle of radius from an arbitrary number of cubic Bézier curves. Let the arc start at point A {\displaystyle \mathbf {A} } and end at point B {\displaystyle \mathbf {B} } , placed at equal distances above and below the x-axis, spanning an arc of angle θ = 2 ϕ {\displaystyle \theta =2\phi } :
Subdivide now each line segment of this polygon with the ratio : and connect the points you get. This way you arrive at the new polygon having one fewer segment. Repeat the process until you arrive at the single point – this is the point of the curve corresponding to the parameter .
The mathematical basis for Bézier curves—the Bernstein polynomials—was established in 1912, but the polynomials were not applied to graphics until some 50 years later when mathematician Paul de Casteljau in 1959 developed de Casteljau's algorithm, a numerically stable method for evaluating the curves, and became the first to apply them to computer-aided design at French automaker Citroën ...

Bézier surfaces are a species of mathematical spline used in computer graphics, computer-aided design, and finite element modeling. As with Bézier curves, a Bézier surface is defined by a set of control points.
Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points.

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]
