WebDec 12, 2014 · A circle is always determined by three points. If you have six points, find two circles determined by disjoint subsets of three points and determine if the two circles are equal. If there are, then all six points lie on the same circle – m_goldberg Dec 12, 2012 at 21:22 2 Orthogonalize can be your friend here. WebFor an optimization fit, you need a good starting point. You could: pick 3 reasonably separated points and fit a circle to them, or find the plane that best fits the N points, project all points onto the plane and then find the circle best fitting these using the algebraic or approximate Euclidean distance planar circle fit. newport oregon courthouse
