Actually, a Bezier curve is between two points (its end points). It does
of course depend on two other points that influence the shape of the
curve, but these points are not *on* the curve; the end-points are the
only points you specify that actually lie *on* the curve.

I believe you probably are interested in a field of math referred to as
"cubic polynomials".
