Hi everyone, I am trying to calculate height value of the terrain on a given latitude and longitude. I am using a ive formatted terrain model that was converted using osgDem from Dted level-1 data. I searched a solution on whole osg forum and web but i could not find good one. Also I looked HeightAboveTerrain class and osgintersection sample but these class does not work only given a latitude and longitude values.
I can get height on terrain with following code block, is it a good solution? Code: osg::PagedLOD* pLod = dynamic_cast<osg::PagedLOD*>(coordinateSystemNode->getChild(0)); osgTerrain::TerrainTile* pTopTile = dynamic_cast<osgTerrain::TerrainTile*>(pLod->getChild(0)); osgTerrain::HeightFieldLayer* pLayer = dynamic_cast<osgTerrain::HeightFieldLayer*>(pTopTile->getElevationLayer()); pLayer->getInterpolatedValidValue( osg::DegreesToRadians(langVal), osg::DegreesToRadians(longVal), height ); Cheers, ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=53687#53687 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
