摘要
受计算机硬件条件限制,大区域河道水面模拟因其数据量大、仿真精度要求高而变得异常复杂。以大范围流域内的水面模拟为研究对象,详细阐述了基于多细节层次(LOD)技术的河流分段建模方法,并在此基础上,结合动态纹理映射技术、多重纹理技术及光照模型提出了一种具有较高绘制效率和视觉效果的模拟方法,该方法在具体的工程实例中得到了验证。
Being restricted by the condition of computer hardware,the simulation of the water in large area has been becoming a very complicated research problem because of the large data size and its high-precision requirement.This paper focuses on the simulation of the water in large area,a sectioning method based on levels of detail（LOD）is described in detail,and the proposed water simulation approach,which has higher rendering efficiency and visual effects,is the combination of dynamic texture mapping,multi-texture mapping,as well as an illumination model.These technologies are eventually applied to engineering practice.
