from the control points of a cubic two-dimensional
B{\'e}zier curve, the geometric form of the curve
(arch, single inflection, two inflections, cusp, loop,
or the degenerate forms straight line or point). The
algorithm is based on a case analysis of the signs for
the determinants of the control-point triples. Source
