/** Helper class for setting up and acquiring height above terrain intersections with terrain.
* By default assigns a osgSim::DatabaseCacheReadCallback that enables automatic loading
* of external PagedLOD tiles to ensure that the highest level of detail is used in intersections.
* This automatic loading of tiles is done by the intersection traversal that is done within
* the computeIntersections(..) method, so can result in long intersection times when external
* tiles have to be loaded.
* The external loading of tiles can be disabled by removing the read callback, this is done by
* calling the setDatabaseCacheReadCallback(DatabaseCacheReadCallback*) method with a value of 0.*/
