摘　　要：高速公路一般具有线性、狭长的特性,如何快速有效地生成、绘制大规模地形成为高速公路视景仿真的关键。为解决该问题,从宏观上提出了一种按道路线形进行地形划分的方案,将大规模地形转换为小块地形进行处理。为了解决多地形块之间的拼接问题,提出了一种多地形块之间的边缘融合算法,同时对多地形块采用动态调度策略来实现交互式实时漫游。实验结果表明,该算法能够有效地实现高速公路大规模地形的快速生成和渲染。Generally,highway has a linear,narrow feature.It is the key for highway visual simulation that how to generate and draw large-scale terrain fast and efficiently.To solve the problem,a terrain block scheme was proposed based on road alignment at the macro.The total terrain was converted to small blocks.In order to solve the multi-terrain connection problem between blocks,a more smooth transition algorithm was declared while multi-terrain blocks dynamic scheduling strategy was used to achieve an interactive real-time roaming.Experimental results show that the algorithm can resolve the generation and rendering of large-scale terrain effectively on the highway.
