Hi,

I want to position something (let's say a building) to a terrain. Currently I'm getting the Z value for the building doing this with an osgUtil::IntersectVisitor and that works fine for static terrains. When I run on a paging terrain (like one from osgEarth) and I position the building, I get a Z value of the lowest LOD. Then more data pages in and the building gets "buried" underground as more accurate data comes available.

What's the most effiecient "ground clamp" things to paging terrain?

Thanks,
Brett
