“…In addition to these approaches, dimensional extension approach of synthesizing 2D simulation into 3D animation was proposed by [22] for animating a wave by synthesizing 2D velocity field, whereas in [23] a large-scale explosion was animated by using cylindrical interpolation with Kolmogorov spectrum. In [24] and [25], a noise-based synthesis was used in order to animate a surging breaker.…”

We present a simple and efficient method for animating different types of water flows with emphasis on a surging wave. The method employs a stochastic approach of extending 2D simulation data into 3D animation space. For the reality of a wave motion along the direction of its dominant propagation, we utilize a physically-based, particle simulation at the pre-processing step and extract surface and splash particles only. At the animation step, these 2D surface frames are stochastically sampled along the transverse direction in the animation time and slice (called time-slice) domain with the aid of a user-defined noise function. For the surface reconstruction in 3D, we use a geometrical technique with a smoothing filter in order to remedy undesired 2D artifacts that result from the slice sampling. In conjunction with appropriate supplements, we apply our method to other types of water flows, indicating further interesting applications of a ripple wave and a whirlpool rotation.

“…To alleviate the complexity of a three-dimensional simulation of water flow on terrains, some works [22,33,34,26] focus only on what is seen in brooks and rivers, i.e., waves and ripples on the water surface near the vicinity of obstacles and banks. The water surface is assumed to be twodimensional and discretized in a regular grid to run the fluid simulation.…”

We present an optimization of the height-field water-column based approach for water simulation, providing three-dimensional animation of water flow on natural terrains. Our approach eliminates the storage and management of redundant virtual pipes between columns of water and also removes output dependency for parallel implementation, making it efficient for interactive computer graphics applications. We show a GPU implementation of the proposed method that runs at interactive frame rates with rich lighting effects on the water surface, including light wavelength dependent attenuation and light scattering.

We present an optimization of the water column-based heightfield approach of water simulation by reducing memory footprint and promoting parallel implementation. The simulation still provides three-dimensional fluid animation suitable for water flowing on irregular terrains, intended for interactive applications. Our approach avoids the creation and storage of redundant virtual pipes between columns of water, and removes output dependency for the parallel implementation. We show a GPU implementation of the proposed method that runs at near interactive frame rates with rich lighting effects on the water surface, making it efficient for water animation on natural terrains for Computer Graphics.
