Real-Time Sand Simulation

The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather than on a physically-based accurate simulation of a granular system.

Those models lack generality when interacting with the environment; in most cases, no reaction forces are computed, considering only soil deformation. This limitation reduces their usability in applications such as driving simulators.

We propose the use of theoretical models for 3D real-time simulation of granular systems. Our goal is to obtain interactive terrain simulation considering a wider range of interactions.
