一种基于TIN的视相关动态多分辨率地形模型

A View dependent Dynamic Multi Resolution Terrain Model of TIN

  • 摘要: 提出了一种基于不规则三角网的"回"结构分辨率的LOD(level of detail)算法,真正实现了离视点越近越清楚、越远越模糊的视觉效果,避免了在模型简化过程中的交叉、重叠和细长的三角形出现。实验结果表明,该算法能实时动态地生成不规则格网的连续多分辨率模型,实现地形场景的平滑绘制,同时具有较快的显示速度。

     

    Abstract: A "hui" structure LOD(level of detail) model TIN based is presented in this paper. The algorithm achieves the experiment effect: the nearer the terrain is away from the viewpoint, the clearer it is. It avoids the triangles crossing or overlapping, and creating some thin triangles. The experiment shows that with this algorithm, the dynamic continuous terrain multi-resolution model will come true.
