Local metamorphosis of functionally defined shapes

ABSTRACT

We propose a new operation to locally control the metamorphosis of two functionally defined shapes. To implement this operation, a set of non-overlapping space partitions is introduced, where the metamorphosis occurs locally. The sequence of local metamorphosis processes is controlled by a specific time schedule. The definitions of the partitions, of the time schedule, and finally of the local metamorphosis operation, are described in this paper. Experimental results and comparison with the traditional metamorphosis operations are also provided.
