摘要
针对大规模地形场景三维实时漫游显示中存在的技术问题 ,提出应用虚拟现实有关技术的思想 ,着重解决地形的多级分块表示、纹理多级贴图中数据结构组织的有关问题 。
In order to solve the questions of real time display of large scale three dimensional terrain, this article put forward the idea of applying virtual reality. The emphases are given to disceussion of the multi level and multi block expression of terrain model and the organization of texture data. In the paper, LOD(Level of Detail) is applied to construct terrain model, Clip textures and mipmap textures are used to map the surface of models. At last, an example of real time display of a large scale terrain scene is showed.
