Decomposition and reconstruction of freeform curve based on reverse subdivision scheme
基于逆细分的自由曲线分解与重建*

In order to achieve multi-resolution representation of freedom curve, this paper gave the generalized reverse Chaikin subdivision based on the reverse geometry, then established decomposition rules based on two parameters, and proposed the optimal decomposition and reconstruction rules of freeform curves by analyzing the optimal parameters and establishing the error vectors. The algorithm is simpler in construction, more obvious in geometrical meaning and easier to spread to other subdivision scheme than previous related techniques.
