Fluid simulation is widely used in the creative industry (movie production and computer games), for realistic and stunning visual effects of scenes involving fluid movement, wind, smoke and steam flows where a natural effect is required. Currently during movie production water sources are filmed over a two day period, which is a slow process and results are unpredictable. Engineers at Swansea University have developed a technology for creating special effects in films and video games by controlling and editing films showing the flow of fluids such as smoke or steam. This type of simulation is usually performed on supercomputers in order to generate sufficient fine-scale features.
This novel technique provides a quicker process than known systems 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. Layers of computer graphics allow novel computational technologies and highly efficient codes to produce visually-realistic animations of various practical fluids including gaseous and liquid fluids, multiphase and multi-component flow, and fluid-structure interaction.
This technology reduces time spent to work out flows to be used in computer animated films and games. Animators, designers and directors of visually impressive games, films and applications will ultimately benefit from this technology.
A patent has been filed for this technology by Swansea University under GB 1113813.8.
