| 摘 要： | 文章在分形理论的基础上,利用Diamond-Square算法,实现了三维自然场景中地形、海面和云彩的动态仿真。既做到了对地形和波形总体轮廓的控制,又充分利用分形特性表现了地面、波面和云彩的丰富细节。并实现了波面和天空云彩的动态效果,增强了虚拟场景的动态真实感。与传统静态的方法相比,这种方法具有较高的真实性、多样性和实时性,可满足虚拟场景交互显示的需要。

| Abstract: | Based on the study of fractal theory and Diamond-square Algorithm,the dynamic simulation of terrain,ocean wave and cloud in 3D natural scenes have been realized.It can both control the shape of terrain and wave and represent abundant details of terrain surface,wave surface and cloud.The movement effect of wave and sky cloud have been realized,the dynamic and realistic feeling is strengthened.Compared with the traditional static method,this method is realistic,multiplicity and real-time;may satisfy the need of interaction in virtual scenes. |
