【摘要】：针对地形场景信息多通道绘制,可提高地形场景的绘图质量。在进行地形场景信息多通道绘制时,常出现分块场景边界缝隙,需要通过定位可视区域和视点位置,细化地形场景进行消除,但传统方法通过对大规模地形场景进行地理测绘实现绘制,但是不能通过定位可视区域和视点位置,细化地形场景进行消除,在地形场景信息多通道绘制时,数据冗余度过大、绘制时间长,降低了地形场景绘制的效果。提出一种基于分块的地形场景信息多通道优化绘制方法,通过分块策略对地形进行数据加载和分割处理,定位可视区域和视点位置,细化地形场景,消除分块场景边界缝隙,提高计算效率和数据的调度速度,利用相邻帧的相关性改善绘制速度,对数据进行预取和实时装载,最终实现对地形场景信息的多通道优化绘制。仿真结果表明,提出的方法高效可行,提高了绘制时间、速度及数据量,为绘制真实性提供理论依据。
[Abstract]:Multi-channel rendering of terrain scene information can improve the quality of terrain scene drawing. In the multi-channel rendering of terrain scene information, there is often a block scene boundary gap, which needs to be eliminated by locating the visible area and viewpoint position, and thinning the terrain scene. However, the traditional method can not be used to locate the visual area and view point to eliminate the terrain scene by geographic mapping, and the data redundancy is very large when the terrain scene information is drawn by multi-channel. The rendering time is long, which reduces the effect of terrain scene rendering. This paper presents a multi-channel optimal rendering method of terrain scene information based on block, which can load and segment terrain data, locate visual area and view position, refine terrain scene and eliminate boundary gap of block scene. The efficiency of computation and the scheduling speed of data are improved, the rendering speed is improved by using the correlation of adjacent frames, and the data is prefetched and loaded in real time. Finally, the multi-channel optimization rendering of terrain scene information is realized. The simulation results show that the proposed method is efficient and feasible, improves the rendering time, speed and volume of data, and provides a theoretical basis for the authenticity of rendering.
