## A Dimension-reduced Pressure Solver for Liquid Simulations

Ryoichi Ando, Nils Thuerey, Chris Wojtan This work presents a method for efficiently simplifying the pressure projection step in a liquid simulation. We first devise a straightforward dimension reduction technique that dramatically reduces the cost of solving the pressure projection. Next, we introduce a novel change of basis that satisfies free-surface boundary conditions {\em exactly}, […]
