Abstract | In this project a new approximation of the Shallow Water equations is used to simulate large-scale uids in real-time. The simulation has been tested against a Smoothed Particle Hydrodynamics model with reasonable results. However, artifacts occur when it is tested with bumps on the ground thus improvements are needed before the approximation can be used as a general purpose solver of large-scale uids.
The visualization of the uid has signi cant in uence on the way a user experience the uid. By extending the visualization with ying foam the average user believes that it is large scale uid in contrast to a visualization without foam. The foam has been modelled by transparent billboards and lines thus it requires a lot of blending to get a smooth transition between the opaque uid surface and the transparent foam. Therefore an e ective blending system has been implemented at the boundary of the uid to save the pixelshader from a lot of work. |
