%X This paper presents a technique for modeling and animating ﬁberlike 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
