Though there is much research on physically-based animation of soft bodies, simulating soft body objects in real-time remains challenging problem. This paper presents an algorithm for simulating leaking effects in real-time soft body simulations where fast calculation is priority. To simulate leaking effects in a soft body, geometrical cases of broken springs are defined and an algorithm rearranges the topology of neighbors in which the broken springs are connected. Then, internal forces are applied to surface points to model the leaking effect and deform the soft body. Experiments show that the soft body objects with leaking effects can be realistically simulated at interactive speeds on common hardware.
