Hi, I need to get the best heightfield reading I can out of an osgTerrain database at runtime. At the moment I am doing something like this:
Code: osg::Node *pNode = osgDB::readNodeFile((const char *)fname_local); // Top level node should be a coordinate system node osg::CoordinateSystemNode *pCoordSystem = dynamic_cast<osg::CoordinateSystemNode*>(pNode); // next node down should be a PageLOD osg::PagedLOD *pLod = dynamic_cast<osg::PagedLOD*>(pCoordSystem->getChild(0)); osgTerrain::TerrainTile *pTopTile = dynamic_cast<osgTerrain::TerrainTile*>(pLod->getChild(0)); m_pLayer = pTopTile->getElevationLayer(); ... Then m_pLayer->getLocator()->convertModelToLocal(Model, Local); // Get the Altitude m_pLayer->getInterpolatedValue(Local.x(), Local.y(), fAltitude); What I would really like to do is to drill down to the best LOD, ensure that that heightfield tile is loaded and query it directly Has anyone got any tips or example code on how to do this. Thank you!
