Water wave animation via wavefront parameter interpolation - Jeschke, Stefan; Wojtan, Christopher J; Deep Pictures: Creating Visual and Haptic Vector Images; Efficient Simulation of Natural Phenomena at Extremely Large Scales (ACM Transactions on Graphics, 2015)
We present an efficient wavefront tracking algorithm for animating bodies of water that interact with their environment. Our contributions include: a novel wavefront tracking technique that enables dispersion, refraction, reflection, and diffraction in the same simulation; a unique multivalued function interpolation method that enables our simulations to elegantly sidestep the Nyquist limit; a dispersion approximation for efficiently amplifying the number of simulated waves by several orders of magnitude; and additional extensions that allow for time-dependent effects and interactive artistic editing of the resulting animation. Our contributions combine to give us multitudes more wave details than similar algorithms, while maintaining high frame rates and allowing close camera zooms.
