Title
Body
(Follow-up of this question .) Given a sequence of cubic Bézier curves, how can I modify them minimally to make them join in a C2-continuous way? Input: curve P with control points P0 , P1 , P2 , P3 curve Q with control points Q0 , Q1 , Q2 , Q3 if it helps, you can assume that they are already C1 continuous. Constraints: C0 continuity: P3 = Q0 C1 continuity: P2 - P3 = Q0 - Q1 C2 continuity: P1 - 2*P2 + P3 = Q0 - 2*Q1 + Q2 modified curves as close as possible to original curves P and Q
