We present a new approach for simplifying polygonal objects. Our method is general in that it works on models that contain both non-manifold geometry and surface attributes. It is...

We describe a method for animating incompressible liquids with detailed free surfaces. For each time step, semiLagrangian contouring computes a new fluid boundary (represented as ...
