- Suppose an open uniform cubic B-spline curve Q(t),0<= t<= 1 which is defined
- by control points V1, V2, V3 and V4.
-
- Is it possible to find a uniform cubic B-spline curve C(u)=Q(t), whose control
- points are W1,..,Wn and first and last control points are
- triple points:
- Q(0) = W1 = W2 = W3 and Q(1) = Wn-2 = Wn-1 = Wn ?
-
- Any help or reference appreciated.
