Abstract :
We present a modified blending subdivision scheme achieving C1 continuity with extensive applications. The main idea is to find the relationship between interpolating subdivision schemes and approximating subdivision schemes. We introduce a parameter to control transition from approximation to interpolation. Our method can produce a limit curve intervening between approximating and interpolating. Experiments have shown that this new scheme can solve the noticeable ¿shrinking effects¿ occurring in interpolating subdivision schemes and ¿popping effects¿ occurring in approximating schemes.
