Alright, I hope this makes some sense.
I am using a software that can create arcs. This arc is defined by: Begin point End point Center of "circle"
The center is supposed to be the center of the imaginary circle that these two points bind to.
Here is a bad picture:
I know p1 and p2. I know the circle is a perfect circle. I have no idea what the proper way to get the circle midpoint is!
