Development of Real Time Virtual Aquarium System

Water or any fluid similar to water in form among various fluids is highly utilized in animation production, and its application scope is quite broad. Therefore, the production of software generating fluid expression, which is easy to be intuitively used, may be quite important. Water, however, is more difficult for simulation than smoke or gas in generation of a fluid effect through an application of a fluid mechanics technique based on physics. In addition, an excessive numerical dispersion problem should be solved. This paper presented a method to develop a fluid mechanics-based fluid expression generator and control the flow of fluid. Also, a method to build a virtual aquarium environment system that can be controllable in real time was presented by expressing the movement of seaweeds using virtual fish and control points based on the spring-mass model in this paper.
