Abstract :
The authors present a new subdivision method for modeling 3D objects with significant discontinuities. We employ a differential operator to detect significant feature curves, and then use a combined interpolatory subdivision algorithm to refine the initial control mesh. The limit surface of the combined subdivision scheme is C1 smooth, except near the detected feature curves where it is C0 continuous
