public interface ILcdCircularArcByBulge extends ILcdCircularArc
More specifically, consider the chord between start and end point (dashed line between S and E in the picture), with a point C in the middle of it. The midpoint M of the arc is located on a line that starts from C and is oriented along the normal. The bulge factor is the ratio of the distance of MC and SC. The sign of the bulge indicates whether the midpoint is on the left side (positive, as in the picture) or right side (negative) of the vector from start to end point.
The following image clarifies the properties of a circular arcbybulge. The arc is represented in black, the start, end and mid points in red and the chord and line from the mid point to the chord in grey.
A circular arcbybulge where the start and end point coincide represents an arc on a circle with these points as its center and a radius of 0. The start angle and arc angle are undefined in this case.
