Designing and Implementation of Waterfall In 3D Dynamic Terrain

<b<Objective:</b< 3D Terrain simulation is a necessary task in the development of outside visual sysytem. <b<Methods:</b< In this paper, a method of particle system is presented to simulate waterfall movement. <b<Results:</b< Waterfall movement is simulated through the variance of particle effect and density functions.Particle present and particle system theory is described first. <b<Conclusion:</b< This a method based on particle system to draw a fast 3D terrain is introduced.
