PagedGeo and PLSM2 Question

Hi i've got a newbie question... I came across the wiki on using PagedGeometry with the PLSM2, but i'm wondering if PagedGeo does paging right

so then why would i want to put both pagedgeometry and PLSM2 together. Can't i just add objects to the screen using pagedgeo.

PagedGeometry is intended for the efficient rendering of trees / bushes / grass / other small objects. PLSM2 is intended for the efficient rendering of LOD terrains. Terrains and the objects put on them are two very different classes of optimization, which is why there's a separate library for each.
