Abstract: This paper presents an automatic animation system for jellyfish that accounts for interaction between the organism and its surroundings. We endeavor to model the jellyfish’s morphology, as well as its achieved thrust. We physically simulate the elastic body of the jellyfish and its surrounding sea water. We use a modified immersed boundary method to combine spring-mass systems and a grid-based semi-Lagrangian fluid solver. The resulting simulations are efficient with an acceptable compromise in physical accuracy. We reduce our model for axially symmetric species to 2D, and extrapolate the results to 3D. We add detail to the 3D shape with noise that is inspired by empirical observations of real jellyfish. We also suggest suitable contraction functions so that our virtual jellyfish propells itself within the water in a manner similar to the real organism. The resulting system is capable of animating jellyfish in real-time on modest desktop hardware.
