public interface ILcdCircleBy3Points extends ILcdCircle, ILcdRing
A circle that is defined by 3 points (start, first intermediate and second intermediate). The start and end point of the curve coincide.

A circle-by-3-points where the start, end and intermediate point coincide represents a circle with these points as its center and a radius of 0. The start angle and arc angle are undefined in this case.

A circle-by-3-points where 2 out of 3 points coincide represents a circle with its center located in the middle between the 2 coinciding points and the other point. The radius of this circle is determined as in the case with 3 different points (the distance between the center and the 3 points). The start angle and arc angle are undefined in this case.
