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