We define the center position of our circle and then ask each pixel how far from that
|

center position it is. This will give the pixel a value between 0 – 1.
|
||
We can then ask the pixel if its value is lower or higher than a predefined value.
|
||
If it is higher we will set the pixel to white
|
||
and if it is lower we will set it to black.
