实时交互的多分辨率地形模型

Real-Time Interactive Multiresolution Terrain Model

  • 摘要: 实现了一种基于视点的实时交互的多分辨率地形模型,在数据结构、空间连续性、时间连续性、视景体裁剪、扇形绘制和纹理映射等方面详细讨论了该模型实现的技术细节。试验表明,该算法简单、有效,大大加快了图形显示速度,并节约了内存空间。

     

    Abstract: This paper comprehensively analyses the typical characteristic of multi-resolution terrain models,uses a hidden quadtree and resolution choosing formula to set up data models,realizes a real-time interactive multi-resolution terrain model depending on eyes.Finally,the experiments are done and some useful results are given.
