[osg-users] Clamping models to an osgTerrain

[SHAYNE TUELLER]

Hi Brad,

I'm assuming you've looked at the osgSim class? It has the ability to query where the ground is at the highest LOD of the terrain. It has other methods you can use to interact with osgTerrain that may be able to help you.

This way the models just get loaded in with the PagedLOD and are already at the right height as the terrain height pops up and down based on the LOD.
