| 摘 要： | 提出了一种基于PC集群的大规模三维战场电磁环境并行绘制方法。该方法采用直接体绘制的三维体数据可视化方法；利用空间八叉树对电磁绘制区间进行空间分割，并采用先序遍历八叉树叶节点的方式进行任务分配；采用Binary-swap算法对各PC节点的生成图像逐次进行全屏幕深度合成。实验表明，该方法能够较好满足大规模战场电磁环境实时可视化的要求。

| Abstract: | A parallel rendering method of large-scale battlefield electromagnetism based on PC cluster is proposed.This meth-od adopts ray casting direct volume rendering algorithm to render the electromagnetic environment,uses Octree to divide the rendering space and adopts preorder traversal Octree method to distribute the divided space.At last,Binary-swap algorithm is used to compose the images which are produced by PC nodes of PC cluster.Experiments show that the method can effectively satisfy the real time rendering of large-scale battlefield electromagnetic environment. |
