Stochastic shape-perturbation, called shape- or hyper-texturing, represents an attractive way for rendering many complex surface structures including fur, fire, cotton or rocks. While current methods often limit applications to static, isolated and rather simple objects, this paper attempts to provide a more general approach, based on projection schemes. The presented technique not only permits to deal with various shapes, but furthermore combines perturbation with animation using 3D deformation models based on a principle of smoothed particles. The parameters of the deformation are controlled by the user through projection primitives". Examples of animated surface behaviors (applied to usual polyhedrons such as the Utah teapot) including morphing, fluttering, burning and waving illustrate the possibilities of the approach."
