The PagedGeometry engine is an add-on to the OGRE Graphics Engine, which provides highly optimized methods for rendering massive amounts of small meshes covering a possibly infinite area. This is especially well suited for dense forests and outdoor scenes, with millions of trees, bushes, grass, rocks, etc., etc.
