Abstract
A planetary scale object rendering system may provide a plurality of spherical mesh topologies of different levels of detail made up of abutting faces. Tessellation of the faces may be provided at continuous levels of detail. The geometry data at different locations and levels of detail in the mesh topology may be randomly accessible. The geometric data may be organized in quadtrees in some embodiments. A layered quadtree data structure may be formed from the bottom layer up with successively higher parent layers formed from the root nodes of previous child layers. The quadtree structure may be randomly accessed from the top down.
