TPNAME:Christopher Batty
TPTITLE:YAAPS: Yet Another Adaptive Poisson Solve
TPABSTRACT:I will discuss a recent SIGGRAPH submission of mine, in collaboration with some folks at UW-Madison, regarding (you guessed it!) fluid simulation. The central goal is to construct an efficient spatially adaptive discretization of the Poisson problem on octrees, which we use to enforce liquid's incompressibility, while preserving 2nd order accurate pressures; visually this corresponds to artifact-free, smooth flows. The "trick" is to conceptually convert the octree structure into a power diagram (a relative of the Voronoi diagram) which has some useful geometric properties in this setting.
