Abstract: Generation of water animation with the style of paper-cuts by hand is a laborious task.In this paper a method is proposed for generating water animation with some patterns that emulate the style of hand-made paper-cuts.By the method,first we classify the hand-made paper-cut water patterns into different types,and then construct their models as well as dynamic control mechanisms corresponding to various patterns.During the phase of animation,we arrange various water patterns in space and time,including spray patterns appearing on water wave patterns and those surrounding moving objects on the water surface.With our system,users only need to specify positions of some wave patterns to generate smooth water animations with the style of paper-cuts.Examples are also given in the paper to show the validity of the method.
