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和基于网格划分的实时LOD分层方法着重解决地形的多级分块表示及纹理贴图,最后采用OpenGL库在VC++6.0上实现某一大场景地区的地形多分辨率三维实时漫游显示。
The technique problems of the large 3D terrain＇s real- time walkthrough are explored in this paper, and a effective method to solve the multi- level blocks of terrain which based on the mesh division is put forward and the virtual reality methods are used to render the texture. Finally, the OpenGL and VC ＋ ＋ 6.0 is used to realize a large scene of terrain and its real - time walkthrough.
