The osgGIS samples you see are actual terrain-conforming geometry (as opposed to projected texture). There are trade-offs to each approach, of course. The convenient thing about OverlayNode is that it doesn't know or care about multiple terrain LODs. With geometry clamping, you have to pick an LOD to which to conform. Paging complicates the issue, esp w/ TerraPage, which doesn't have a "default" LOD-zero like osgdem datasets do IIRC. -gw -- Glenn Waldron : Pelican Mapping : http://pelicanmapping.com : 703-652-4791
