Bresenham’s Circle Algorithm

Hey guys!
Today we will be learning another approach to drawing circles in Computer Graphics. Basically another approach to the same task we tackled in the previous post. Bresenham’s Circle Algorithm follows the footsteps of Midpoint Circle Algorithm, both working for the same purpose in slightly different ways. Let us see how.

Graphic Design | Midpoint Circle Algorithm

Hi guys! How're you doing?
If you've been following me, we have studied of two methods that help us in drawing a line; The DDA and Bresenham Line Algorithm. We would now want to hence extend our knowledge and draw different things, more complex than a line, isn't it? Here you have it, today we would learn about a method to draw circle. The Mid-Point Circle Algorithm!

Graphic Design | Bresenham's Line Algorithm

Hey guys! How are you doing?

In the last post here we learnt about the Digital Differential Analyzer Algorithm. It helps us to plot lines in a very easy way. However it is not the very best of the available approaches we have when it comes to plotting a line.
For example, we have another technique called the Bresenham's Line Algorithm which we are going to study today, which is a much better approach than the Digital Differential Analyzer Algorithm we studied earlier, here.

Graphic Design | Digital Differential Analyzer (DDA) Algorithm

Heyo everyone! How're you doing?

Today we are going to understand a very basic algorithm in Computer Graphics, The DDA or Digital Differential Analyzer Algorithm.

Now before we get started, we should get an understanding about what DDA is and also rather what an algorithm is.

Now DDA is a line drawing algorithm. From all I can say right now, DDA is a basic algorithm used to print lines on your standard output ie. the monitor using, well, the starting point and the ending point of the lines, the starting and ending coordinate of the line that you are going to plot.
