ROAM method adopts split and merge operations to adjust triangle meshes, can interactively perform view-dependent, locally-adaptive terrain meshing and can construct multiresolution terrain model.
ROAM算法就是通过采用分解和合并方法实时地调整三角形网格,能交互式地实现观察依赖、局部可调整的地形网格化处理,生成多分辨率的地形模型。
To represent dynamic multiresolution terrain in real time, two sorts of models suitable for current stage are proposed, the adaptive quadtree model and the implied quadtree model.
