About
View-dependent multiscale fluid simulation. Fluid simulation is widely used in the creative industry (movie production and computer games), for realistic and stunning visual effects of natural scenes involving fluid flows. For creating special effects in films, this type of simulation is usually performed on supercomputers in order to generate sufficient fine-scale features. For game users, the visual quality has to be significantly scarified due to limited computing resources. This novel technique uses viewing information to save computational cost while giving richer fine-scale details for the space that can be observed by the viewer. This is based on a novel idea of flow field decomposition, based on which a series of new tools have been developed for graphical fluid simulations. These new tools dramatically improve the computational efficiency (by several orders in many cases) with more realistic fine features of turbulent flows.
