摘要
为了实现三维海岸地形的可视化,需要解决建模和消隐处理两个关键问题.针对海岸地形场景的特点,选取中点位移法实现数字高程模型建模.在建模基础上,采用深度缓冲器算法进行消隐处理,进而实现三维真实感海岸地形场景的可视化.实验结果表明,所提出的方法成功且有效.
In order to realize the visualization of 3D coastal landform, two key issues on modeling and hidden processing are needed. In view of the characteristics of the coastal landform scene, the midpoint displacement method is selected to realize the digital elevation model. Based on the mod- el, the depth buffer method is used to eliminate the hidden processing, which then realizes the visualization. The experimental results show that the method proposed in this paper is successful and effective.
