Capillary waves are difficult to simulate due their fast traveling speed and high frequency. In this paper, we propose approximate capillary wave effects by surface compression under the SPH framework. To achieve goal, present a method convert tension energy changes measured from simulation into high-frequency density variations. Based on propagation model, an technique in particle field. address noise issues simulation, develop simple way apply zero pressure condition free surfaces projection-based incompressible SPH. Our experiment shows that developed algorithm can produce realistic both thin liquid features large bodies. Its computational overhead is also small.
