摘要: 提出了一种基于自适应四叉树多分辨率实时动态地形生成模型,算法包括对原始数据自适应输入和静 态裁剪、更新了误差判断准则、开发了帧间连贯性。实验表明,该算法简单、有效,支持对地表模型的交互式实时 动态绘制。Abstract: A multiresolution and real-time terrain generation model based on adaptive quadtree is presented. The algorithm of the model includes the adaptive inputting and static culling of raw data, renewing of error evaluation criterion, and frame-to-frame coherence. Experimental results show that this algorithm is simple and effective, and supports the interactive and real-time rendering of terrain surface models.
