Abstract
Physically-based simulation modeling is to simulate the real world by using physical laws such as Newton's second law of motion, while other modelings use only geometric Properties. In this paper, we present a real time simulation of stone skipping by using the physically-based modeling. We also describe interaction of a stone on the surface of water, and focus on calculating the path of the stone and the natural phenomena of water The path is decided by velocity of the stone and drag force from the water The motion is recalculated until the stone is immersing into the water surface. Our simulation provides a natural motion of stone skippings in real time. And the motion of stone skippings are generated by give interactive displays on the PC platforms. The techniques presented can easily be extended to simulate other interactive dynamics systems.
