Bresenham Circle VS others

[Liamtoh Resu]

I find these graphics programs fascinating.

I had to grok m's code to figure out how to get an output from c's code.
(eg. 160,120,100,255) gave me a blue circle.

Explanations of bresenham's algorithm tend be very detailed.

Meanwhile I found this link for the bitmap/midpoint circle algorithm:

Thanks again.
