Definition: Special points attached to a node on a Bézier curve that are used to alter the shape and angle of the adjacent curve segment. Stretching the control point manipulates the shape of a curve, rotating the control point manipulates the angle of a curve. The behavior of the control handles is dependent on the type of node it is attached to.
