Power diagrams are a generalization of Voronoi diagrams (and their dual Delaunay mesh), which partitions space with convex polygons. This discretization has a number of advantages when it comes to simulating fluids: the flow across cells can be modelled accurately such that the simulator has low numerical viscosity, and it has excellent volume conservation properties.

In this seminar we will discuss how to build such a simulator, and how it compares to other state-of-the-art methods used for fluid simulation in computer graphics.
