Hair, Cloth and Soft Tissues: The Influence of Mechanical Properties on the Real-Time Dynamics of Deformable Objects

www.eg.org diglib.eg.org Abstract In spite of the impressive advancements achieved during the last years in the domain of interactive physically based simulation, the real-time animation of complex deformable objects still represents a challenge. In order to cope with the resulting computational complexity, researchers continue seeking adequate trade-offs between simulation accuracy and computing performance. One compromise allowing to gain processing power without loosing physical plausibility is selective physically based optimization, i.e. reducing the computations to a predictable amount based on the influence of physical material properties on the mechanical behavior of soft bodies. In this paper, we analyze simulation approaches for structurally different objects and discuss both their specificities and commonalities. We focus on the contribution of physical parameters in the real-time simulation of 1D rods, 2D surfaces and 3D volumes, taking as examples hair, cloth and soft tissues.
