The physically-based animation of real-world environments comprises numerous
challenging problems in areas such as rigid-body dynamics, deformable
modeling, fluid dynamics, collision detection, and contact handling. In this
presentation, challenges in the animation of deformable objects and fluids
with a special emphasis on efficiency and versatility are discussed. In the
context of deformable objects, flexible representations, versatile
deformation models, and efficient approaches to geometric constraints are
presented. In the context of fluid animation, efficient spatial data
structures and numerical aspects are discussed. Applications to
computational medicine, robotics, and entertainment technologies are
outlined.
