摘　　要：鉴于指挥控制系统中三维数字地球平台的态势图形渲染方法普遍存在冗余渲染、中央处理器(CPU)/图形处理器(GPU)计算性能瓶颈等技术缺陷,采用基于相似性特征提取的三维图形渲染优化方法对其进行了改进,并使用了较流行的4种图形批次合并渲染技术进行了实现。同时,利用GPU硬件拾取技术解决了海量图形人机交互时的求交卡顿问题,并在新一代二三维显示平台鲸云地图中进行了验证和调优。最后,经过数据分析和比较,得出了自主可控环境下三维海量态势显示的最优方案。In view of the technical defects of the redundant rendering and the central processing unit (CPU)/graphics processing unit (GPU) computing bottlenecks in the situation graphics rendering methods of the 3D digital earth platform in the command and control system, a 3D graphics rendering optimization method based on similarity feature extraction is adopted to improve it. Four popular graphics batch merge rendering technologies are adopted. At the same time, the GPU hardware picking technology is used to solve the intersection carton problem in the interaction of massive graphics, and it is verified and adjusted in Jingyun-map of the new generation 2D/3D display platform. Finally, the optimization scheme of 3D mass situation display in independent controllable environment is obtained through the data analysis and comparison.
