An ocean scene with multiple waves is displayed (a) from the side and (b) from above; (c) and breaking waves and backflow waves colliding with blocks. The waves combine naturally, while each of them is modeled with its specific parameters (height, width, speed, orientation, crest slope, breaking time). Abstract This paper presents a new method for controlling swells and breaking waves using fluid solvers. With conventional approaches that generate waves by pushing particles with oscillating planes, the resulting waves cannot be controlled easily, and breaking waves are even more difficult to obtain in practice. Instead, we propose to use a new wave model that physically describes the behavior of wave forces. We show that mapping those forces to particles produces various types of waves that can be controlled by the user with only a few parameters. Our method is based on a 2D representation that describes wave speed, width, and height. It handles many swell and wave configurations, with various breaking situations.
