HI Licu, The osgTerrain library has changed roles in the SVN version with the database generation component moved out into their own separate distribution - now the VirtualPlanetBuilder project. This takes the role of generating large scale paged databases.
osgTerrain will now focus on terrain related rendering such as rendering height fields. Very little exists in this direction but we'll slowly fill this out. One needn't use osgTerrain for your own terrain work though, and can just create scene graphs containing nodes, geometry and state as you required. The internal nodes can include PagedLOD or conventioanl LOD nodes, its entirely your choice. I can't really help you in how to go about implementing integration with your app, it all depends upon the terrain modeller and how it creates data and how you wish to view it. Robert.

Hello, I'm writing an export plug-in for a terrain modeling application. I've been browsing the OSG documentation and examples in the last days but I still have some uncertainties. First of, what's the best way to construct the terrain scene graph? For now I've been using osg::Geometry and Drawables to create generic geometry surfaces to represent the terrain zones. I've saw that there is also a osgTerrain but is this only for terrain generation or can it be used to keep and render the terrain data, too? To be noted that the terrain is made of multiple zones with multiple layers of textures and also LOD must be implemented (and maybe some paging mechanism). And another question, if I am to represent the terrain thru normal geometry how do I encode multiple layers of textures (using multi-textures and multi-pass if necessary)? How can I use the same osg::Geometry but with different render states and textures?
