The dynamic simulation of mechanical effects has a long history in computer graphics. The
classical methods in this field discretize Newton's second law in a variety of Lagrangian or …

Many of the actions that we take with our hands involve self-contact and occlusion: shaking
hands, making a fist, or interlacing our fingers while thinking. This use of of our hands …

We present a new discrete velocity-level formulation of frictional contact dynamics that
reduces to a pair of coupled projections and introduce a simple fixed-point property of this …

The physically-based simulation of mechanical effects has been an important research topic
in computer graphics for more than two decades. Classical methods in this field discretize …

We present algorithms for simulating and visualizing the insertion and steering of needles
through deformable tissues for surgical training and planning. Needle insertion is an …

We introduce a new method for efficiently simulating liquid with extreme amounts of spatial
adaptivity. Our method combines several key components to drastically speed up the …

This article describes a Lagrangian finite element method that simulates the behavior of
liquids and solids in a unified framework. Local mesh improvement operations maintain a …

We present a method for accurately tracking the moving surface of deformable materials in a
manner that gracefully handles topological changes. We employ a Lagrangian surface …
