Water simulation for cell based sandbox games

University essay from Linköpings universitet/Linköpings universitet/Institutionen för systemteknikTekniska högskolan

Abstract:

This thesis work presents a new algorithm for simulating fluid based on the Navier-Stokes equations. The algorithm is designed for cell based sandbox games where interactivity and performance are the main priorities. The algorithm enforces mass conservation conservatively instead of enforcing a divergence free velocity field. A global scale pressure model that simulates hydrostatic pressure is used where the pressure propagates between neighboring cells. A prefix sum algorithm is used to only compute work areas that contain fluid.
