Simulation Research On The Water Of Virtual Water Wall System Based On The SPH Algorithm

As the development of computer hardware and software, the technology of virtual reality is being widely used in all kinds of fields. As a result, researches on how to improve the visual effect attract more and more researchers, especially about the simulation of natural landscapes. Though we all see waters, fog and explosions, no one can make an accurate description, for the reason that they are all dynamic. So it is a difficult task to simulate them using computer technology.Water is common to all of us, which is fluid and does not have a fixed shape. Due to its characteristics, water simulation needs lots of calculation which makes it hard to satisfy the real-time requirement. Virtual water wall is a simulation system of water which shows the water on the screen and allows users to operate the water like playing games. The existing water wall systems are far from good not only in visual effects but also in system performance. Some of them even are bound to hardware which increases the difficulties of systems’ transplantation and maintenance.Water is common to all of us, which is fluid and does not have a fixed shape.

Virtual water wall is a simulation system of water which shows the water on the screen and allows users to operate the water like playing games. The existing water wall systems are far from good not only in visual effects but also in system performance. Some of them even are bound to hardware which increases the difficulties of systems’ transplantation and maintenance.As the most successful method to generate irregular shapes so far, particle system can make the simulation of waters like the real ones. SPH method, which is a massless particle system, needs less compute resources in simulate waters without doing harm to the visual effects. At the end of this paper, we use both traditional particle system and the particle system with SPH method to build water wall system. Based on the analysis on the frame rate and memory usage of the two systems, we make our conclusion.
