2D Smooth Particle Hydrodynamics Fluid Simulation

Produced for my fourth year Animation module, this coursework was based on this paper by Müller et al

Unlike other grid-based fluid simulations methods, here fluids are discretised into particles with a certain mass. SPH updates field quantities at discrete locations (the particle’s location) by interpolating the contributions of surrounding particles, scaled by a smoothing kernel. For fluids, the paper describes a formula based on the Navier-Stokes equation using three force density fields modelling pressure, viscosity and external forces.
This was a very interesting piece of coursework and is one I would like to revisit, there are some aspects of the simulation I would like to improve:

• The paper describes adding surface tension to the simulation
• Experimenting with different integration methods and better neighbouring particle searching methods
• Implementing methods for parallelising the simulation (threading, gpu computation)
• Making the simulation 3D
• Implementing geometry generating methods (such as marching cubes) for impressive video renders
