摘要
En 中文
This paper proposes a novel particle-based scheme for simulating interactive water waves. We first modify the implementation of the wave packet so that each packet can carry two wavenumbers. As a consequence, the wavelength-dependent behaviors can be accurately simulated. We then optimize the approximation technique of diffraction for simulating partial diffraction and promoting rendering efficiency. Lastly, we provide a novel evaluation module based on wave patterns generated by solving wave functions. Specifically, we introduce the singular boundary method (SBM) to serve as an analytical solution of the Laplace equation. We tested our scheme and other state-of-the-art approaches on scenes with regular-shaped, complex-shaped, and user-designed obstacles. Various results indicate that, compared to the state of the arts, our scheme can achieve higher physical accuracy and more satisfying computational efficiency.
