The uploaded example uses Zingl's interpretation that you can read about here (page 19).

While comparing to a myriad of Midpoint circle algorithms you can find here, Zingl does not:
- execute pixeldrawing before and after iteration, he does it once.
- use 8 conditions for drawing, but merly 4 (one for each quadrant).
- use any "else" statements, which suits fusion better.
