Large-scale interactive water simulation with directional waves

Simulating large bodies of water in real time has been a research goal for a few decades. Existing procedural approaches like FFT-based simulations typically lack dynamic response like boundary-wave reflections or general body-fluid interactions like splashes or boat wakes. On the other side of the spectrum, existing dynamic Eulerian wave simulations suffer from high memory consumption required for adequate grid sizes in large scenes. Dynamic Lagrangian simulations like wave particles suffer from a potentially prohibitive particle count.
