comment how to find center of an arc given start point, end point, radius, and arc direction?
I am interested in this answer for a cnc machine emulation I am programming. The answer I desire is solved generically for x or y (the other would be trivial given one of them) for both possible points. I have tried to solve this myself, but am getting pretty lost. I tried to solve by (x-a)^2 + (y-b)^2 = (x-c)^2 + (y-d)^2 than plug back in to first equation.
