| 摘 要： | 为了解决地形绘制受制于CPU计算能力的问题,采用可编程图形处理器(graphic processing unit,GPU)来处理多分辨率地形的构造、小波逆变换、动态法线计算等绘制流程计算量比较大的负载,采用客户端数据缓存和数据预取策略,实现了多用户网络地形漫游时绘制质量的控制,实验证明该方案满足了大规模地形漫游的需求.

| Abstract: | To solve the problem of limited CPU computing capacity in terrain rendering,the paper suggests that by using GPU,the structure of multi-resolution terrain,the wavelet inverse transform,and the large calculated load of the dynamic normal computing and so on,are handled.And by using client-side data caching and data pre-fetching strategies,the quality control of multi-user network roaming terrain rendering is achieved.The experiments show that the solution meets the needs of large-scale terrain roaming. |
