  • Patent number: 7917343
    Abstract: A ripple and foam creation apparatus and method using water particle data is provided to create ripples and foam, and detect positions of the created ripples and foam for a water simulation used to create visual special effects in animations or movies. The apparatus includes a water particle grouping module checking grouping types of water particles from received water particle data to selects small water masses, a ripple creation module determining a position for ripple creation by using the checked grouping types, a foam creation module detecting flow of the water particles and calculating a position for foam creation, and a ripple-foam moving/removing module detecting changes of the created foam and ripples over time and removing the created foam and ripples.

  • Publication number: 20090112526
    Abstract: Provided are a system and method for simulating fluid particles having multi-resolution. In the method, given particle data expressing fluid is analyzed in an fluid particle analyzing module so that data for determining resolutions is obtained. A resolution of each of regions is determined using the obtained data in a resolution level determining module. Particles of each of the regions are reformed to particles corresponding to the resolution of each of the regions using the determined resolution of each of the regions in a fluid particle reforming module. Position data of fluid particles of a next frame is obtained after a simulation using the reformed particles in a multi-resolution fluid simulation module. Therefore, the fluid simulation having the high resolution can be performed in limited computing resources by applying different resolutions to each of the regions.
