Abstract
An animation system employs scattered data interpolation to provide fluent animation of still images. Discontinuities, such as cuts and holes, can be established within an image, to limit the range over which interpolation is carried out for a given deformation of a feature in the image, and thereby refine the control exerted by animated features. The amount of computational time and effort required to interpolate the change from one frame of an animation to the next is reduced by concentrating computation of the deformed image on areas of change. Computational requirements are further reduced by taking advantage of frame-to-frame coherence.
