Animation of the biological pollutants propagation on large-scale water surface

摘要：

　　We present a method to animate the propagation of biological pollutants (e.g.,algae,water hyacinth etc.) on largescale water surface.In this paper,we focus on the clusters and large patches of aquatic plants rather than each single aquatic plant.The interface between water surface and the patches is represented by 2D dynamic curve.We present a 2D level set based model to animate the dynamic evolution and propagation of the interface.To handle boundaries in largescale virtual environment,we propose a 2D voxelization method which provides the boundary condition for the level set based propagation model.Finally,we simulate the algae propagation phenomenon in Taihu Lake.The application results show that our method is intuitively implemented and convenient to produce visually interesting results.
