This paper presents a technique for modeling and animating fiber-like objects
such as sea anemones tentacles in real-time. Each fiber is described by a
generalized cylinder defined around an articulated skeleton. The dynamics of
each individual fiber is controlled by a physically based simulation that
updates the position of the skeleton's frames over time. We take into account
the forces generated by the surrounding fluid as well as a stiffness function
describing the bending behavior of the fiber. High level control of the
animation is achieved through the use of four types of singularities to describe
the three-dimensional continuous velocity field representing the fluid. We thus
animate hundreds of fibers by key-framing only a small number of singularities.
We apply this algorithm on a seascape composed of many sea anemones. We also show that our
algorithm is more general and can be applied to other types of objects composed
of fibers such as seagrasses.
