Geometric constraint.

<p>Values of geometric constraint <i>C</i> produced by an external force as time passes. The magnitude of the constraint is represented with color spectrum, from low (blue) to high (red).</p

Stretched cloth.

<p>A stretched cloth is struck by a ball of water, modeled by different methods (left column: our method, middle column: Lenaerts et al.
