【Abstract】 A novel method for nonrigid body motion and metamorphosis is proposed based on morpho translation. Nonrigid body motion can be divided to nonrigid body metamorphosis and rigid body rotation. By decomposing two concave objects into sets of individual convex sub objects respectively and then constructing the mapping between two subsets, the metamorphosis of two concave objects can be described by the coalition of all Minkowski additions of convex subsets. The principle of morph translation is proved theoretically. This method can solve the metamorphosis problems of two non homotopy objects (including concave object and holey object) and get the natural, high quality metamorphosis sequence with simple computation, it also can be used to describe nonrigid body motion, font composition, 3D arbitrary object metamorphosis, interpolation between keyframes in 2D computer animation, model oriented image coding, virtual man machine communication (conversation) , etc.更多还原
