In computer graphics, fluid dynamics are used for animating and expressing the various special effects of water. It takes a fair amount of mathematical work and a lot of time to express the realistic water because the water already has enough of complexity by itself. As the hardware gets better and better, it now is a lot more possible than before to do the real-time simulation of complicated algorithm. However it still cost a lot of time to do the detail expressions, so the research for the balance, between the technology and the reality, is needed. After all expressing the objects like water will eventually face the interaction with the external environment, so to express this; the priority comes to sacrificing the physical reality to preserve the visual reality.
It is very complicated to visualize the water expression that interacts with the external environment, because the reality water expression has to express the physical sequence so the real-time simulation is difficult to make. Also the Wave Equation cannot be done precisely in local control area, though it can actually visualize the large area of the water.
This paper will propose about the techniques to control and visualize the water fluid in large scale and also about the enabling the local controls at the same time, visualizing the water surface by using the height field and linear convolution, and the interaction between 3D object and water surface through Sphere Model, in real-time simulation.
The proposed method supplemented the linear convolution’s problem; the average weight’s application to large scale fluid simulation. Following the usersdemand the method will provide the external environment such as terrain, and the interaction with the object in real-time. So it is expected to create a new type of game playing factor in user dialogism games.
