Drawing a circle on the screen is a little complex than drawing a line. There are two popular algorithms for generating a circle − Bresenhams Algorithm and Midpoint Circle Algorithm. These algorithms are based on the idea of determining the subsequent points required to draw the circle. Let...
COMPUTER graphicsALGORITHMSDRAWINGTECHNOLOGYCIRCLERendering circles on digital platforms is essential in computer graphics. The widely adopted midpoint circle algorithm is a premier tool for this task. This article dives deep into the foundational aspects of this algorithm, highlighti...

It is an eight-way symmetric figure which can be divided into four quadrants and each quadrant has two octants. This symmetry helps in drawing a circle on a computer by knowing only one point of any octant. How to define a circle in computer graphics? There are twomethods to define a c...
In this article, we are going to learn about circle generating algorithms in computer graphics i.e. Midpoint circle algorithm. Derivation of generating midpoint circle algorithm is also prescribed in this article. Submitted by Abhishek Kataria, on August 04, 2018 ...
EDCircles is a real-time, parameter-free circle detection algorithm that works by post-processing the edge segments detected by our parameter-free edge segment detector, edge drawing parameter free (EDPF). EDCircles first converts each edge segment, which is a contiguous chain of pixels, into ...

An algorithm to generate the locus of a circle using the intersection points of straight lines is proposed. The pixels on the circle are plotted independent of one another and the operations involved in finding the locus of the circle from the intersection of straight lines are parallelizable. ...
