However, when it comes to heavily deforming geometry, such as the surface of a splashing liquid, implicit representations are typically preferred because they sidestep traditional challenges relating to remeshing and handling of topology changes. In this talk, I will describe how to effectively and robustly overcome these challenges, and argue that triangle meshes possess key advantages for a range of liquid animation scenarios. Specifically, I will address the simulation of: (1) thin and detailed liquid splashes, using a highly adaptive underlying Voronoi-based simulator; (2) slender sheets of high viscosity liquid, by exploiting a novel reduced dimensional representation; and (3) multimaterial flows, based on a non-manifold triangle mesh with dynamic topology.
