Another way to write a HeightField is using the fact that it is a subclass of osg::Shape.
If you have the hierarchy

osg::Geode -> osg::ShapeDrawable

and then use setShape() to set the height field as the drawable of the ShapeDrawable you can then use writeNodeFile(geode, '...')

Hi @all,

I have tried to save an osg::Heightfield into a file, but it has not
succeeded. Have used the function osgDB::writeHeightFieldFile(*hf, "C:\
\heightfield.osg")).. is the extension wrong or should I install
further plugins (gdal plugin)?

sincerely yours,
Luc
