ROAM

Real-time optimally adapting mesh (ROAM), is a continuous level of detail algorithm that optimizes terrain meshes. On modern computers, sometimes it is more effective to send a small amount of unneeded polygons to the GPU, rather than burden the CPU with LOD calculations -- making algorithms like geomipmapping more effective than ROAM.
