【摘要】 针对城市复杂地形的三维可视化工作,采用扩展规则网格构造地形表面特征,结合树型结构实现数据表示.论证了一种视点相关动态多分辨率地形模型简化的新算法,为实现三维场景的实时显示具有一定借鉴意义。更多还原

【Abstract】 Due to implement the urban topography simulation,the surface feaure has constructed the 3D modeling by solid sculpt.Based on the grid surface model simplification,Disscousse a new algorithm can be applied to generate a viewdependent dynamic multi-resolution model.The research on this subject has considerable value for implementing the 3D visualization system.更多还原
