Abstract

In this paper we argue for the concept of fake dynamics to allow animators to interactively create visually pleasing animations of cloth models while keeping him/her in full control of the animation process. Existing animation and simulation techniques depend on real dynamics simulation and are often prohibitive in terms of computational cost and user control. Our approach allows the user to interactively model and animate cloth models over time using intuitive deformation tools and keyframe animation techniques. During modelling, the cloth’s surface is first approximated by means of 3D catenaries between constraint points. An iterative relaxation process is then performed to arrive at the natural rest shape. Concerning the animation phase, the animator has disposal of many interactive fake dynamics control tools to perform gross modifications or wave-shaped deformations. Multiple instances of deformations can be layered allowing to create realistic as well as exaggerated types of animations. We believe our system is effective in terms of ease-of-use, visual appeal and dynamic behaviour, and offers a new fresh perspective on cloth animation for animated films.
