http://13thmonkey.org/documentation/Graphics/nishita-bezier-clipping.pdf Web1.2 Intersection of a Bezier curve with a line We start with a simple case to illustrate some general paradigms in the intersection algorithms. We assume that the Bezier curve is cubic throughout this section, though the method can be generalized to any degree. Since the curve is cubic, the number of intersection points can be from 0 to 3.
