Hi Robert, Hmm, maybe we talk at cross-purposes:
osgSim::HeightAboveTerrain provides already a convenience Method for HAT calculations: Code: static double computeHeightAboveTerrain(osg::Node* scene, const osg::Vec3d& point, osg::Node::NodeMask traversalMask=0xffffffff); I can't really follow you regarding the computation effort or paging performance, because the HOT calculation is no extra step, it is a by-product of your HAT calculation. I agree that the HAT-class may not be not the best place for HOT calculations. ;) Meanwhile I'll add these functions to the osgVisual utils to provide the users of my department a simple to use interface to query hat / hot. Thank you!
