Abstract: The morphing or metamorphosis of images is often used to generate special effects in films and animation. In many cases only a part of an image will be affected by the morph, and often that part has an irregular shape. This work presents a new interactive technique for performing morphs based on locally interpolating subdivision surface schemes. The technique allows the definition of morph problems between irregular objects with equal genus containing holes and protruding limbs, and their execution in a relatively short time, without losing local control in the interior of objects or their borders. Furthermore, applying subdivision surface methods allows large variations in control point density.
