Hello everyone I''m coding an adaptive quadtree, and i''m now at the point of introducing LOD to it. But as soon as i want to render in less detail, cracks start to appear. Does anyone know how I can get rid of them? Thanks a lot Diablo

Most LOD approaches constrain the quadtree such that the LOD of one node is at most one LOD different from any of its neighbors. This simplifies the cracking problem. If a node has a neighbor of a higher LOD, the node must tell the neighbor to enable vertices to avoid T junctions which cause the cracking.
