WebThe point Z is the zero point, P is the point such that the fraction of the circle from Z to P (in blue) is equal to p.The value of p is precisely the number of blue arcs divided by the total number of arcs. If we let the first clockwise point of an arc define it, then every point on the circle defines one arc with Z defining a blue arc and P defining a non-blue arc.
