Scan Conversion | Circle | Mid Point Method | Computer Graphics

In this tutorial, we dive into the Mid-Point Circle Drawing Algorithm, a fundamental technique in computer graphics for generating circles on raster displays using only integer arithmetic.

We begin by discussing what the mid-point method is, where it’s applied, and why it was developed as an efficient alternative to floating-point heavy approaches. From there, we break down the algorithm step by step, introducing the decision parameter and how it guides the choice of pixels to best approximate the circle’s path.

To make the concept concrete, we work through a detailed example of drawing a circle with center at the origin and radius 6, showing each decision step, updates to the parameter, and how symmetry is used to reduce computation. We’ll also touch on its extension for arcs and ellipses.

Finally, we look at the advantages and drawbacks of the mid-point method, possible modifications like anti-aliased circles, and its connection to modern rendering pipelines and exam preparation topics in computer graphics.

By the end of this session, you’ll not only understand how the Mid-Point Circle Drawing Algorithm works, but also appreciate its importance as a foundation for raster graphics, CAD/CAM systems, and efficient rendering in computer graphics applications.
