Hi,
I am trying to place a model on a vpb terrain by supplying the lat-long
coordinates.
I followed a couple of threads in the forum that suggested to use the
CoordinateSystemNode and ellipsoid model. But that didn't work for me (or maybe
I am not following it right).
I have attached the terrain along with my post.
So far this is what I am doing:
Code:
osg::ref_ptr<osg::Group> root = new osg::Group();
osg::ref_ptr<osg::CoordinateSystemNode> csn = new osg::CoordinateSystemNode();
csn->setEllipsoidModel(new osg::EllipsoidModel());
osg::ref_ptr<osg::Group> terrainGroup = new osg::Group();
//osg::ref_ptr<osg::Node> terrain =
osgDB::readNodeFile("NorthCampus6Levels.osg");
osg::ref_ptr<osg::Node> terrain =
osgDB::readNodeFile("NorthCampus6LevelsNoCS.osg");
terrainGroup->addChild(terrain);
osg::Vec3d m_surface;
csn->getEllipsoidModel()->convertLatLongHeightToXYZ(osg::DegreesToRadians(42.291966f),
osg::DegreesToRadians(-83.715645f), 0.0f,
double(m_surface.x()),double(m_surface.y()),double(m_surface.z())
);
I tried using a visitor to find the CoordSystNode in my scenegraph but when I
checked getEllipsoidModel I got a null.
I have used osgEarth in the past and was able to place a model on that. But I
presently need to use vpb. If anyone can point me in the right direction, it
would be great.
Thank You.
Sincerely,
Sanat
