I am curious if its possible to represent relaxed uniform cubic b-spline curves in knot vector form.
With relaxed uniform cubic b-spline curves, a curve with four control points represents 3 bezier curves that are joined together.
However, a clamped cubic b-spline with four control points must be represented with a knot vector [0,0,0,0,1,1,1,1]. This defines a single bezier curve, not 3 bezier curves that are join together.
Is there a different configuration of b-splines that can achieve the former?
