[osg-users] osgearth 2.4' PlaceNode fails to save as IVE

[Han]

Code:

#include <osg/Notify>
#include <osgViewer/Viewer>
#include <osgEarthUtil/EarthManipulator>
#include <osgEarthUtil/ExampleResources>
#include <osgEarthAnnotation/ModelNode>

#include <osgEarthAnnotation/PlaceNode>


int main()
{
int argc = 2;
char* argv[2];
argv[0] = "*.exe";
argv[1] = "D:\\RUNTIME\\osgearth-3.0.1-2.4\\Release\\tests\\gdal_tiff.earth";

osg::ArgumentParser arguments( &argc, argv );
osg::ref_ptr<osgViewer::Viewer> viewer=new osgViewer::Viewer(arguments);
osg::ref_ptr<osg::Group> group=new osg::Group;

viewer->getDatabasePager()->setUnrefImageDataAfterApplyPolicy( false, false );

osg::ref_ptr<osgEarth::Util::EarthManipulator> em=new osgEarth::Util::EarthManipulator;
viewer->setCameraManipulator(em);

osg::ref_ptr<osg::Node> earthFileNode=osgEarth::Util::MapNodeHelper().load(arguments,viewer);
osgEarth::MapNode* mapNode = osgEarth::MapNode::findMapNode(earthFileNode);

group->addChild(earthFileNode);

//add Annotation:
osgEarth::Symbology::Style AnnotationStyle;
AnnotationStyle.getOrCreate<osgEarth::IconSymbol>()->url()->setLiteral( "D:/EARTH/data/images/PNG/placemark32.png" );
AnnotationStyle.getOrCreate<osgEarth::Annotation::TextSymbol>()->size() =50.0;
const osgEarth::SpatialReference* geoSRS=mapNode->getMapSRS()->getGeographicSRS();
osg::ref_ptr<osgEarth::Annotation::PlaceNode> pn=new osgEarth::Annotation::PlaceNode(mapNode,osgEarth::GeoPoint(geoSRS, -74.00, 40.71), "New York", AnnotationStyle);
group->addChild(pn);

//output Annotation:
osgDB::Registry::instance()->writeNode(*pn,"Annotation.ive",osgDB::Registry::instance()->getOptions());


if ( earthFileNode )
{
viewer->setSceneData( group );

viewer->getCamera()->setNearFarRatio(0.00002);
viewer->getCamera()->setSmallFeatureCullingPixelSize(-1.0f);

viewer->run();
}

return 0;
}






then, i get errer:
Error writing IVE image: StateSet::write(): Unknown StateAttribute: VirtualProgram


How can i ?

You can't save any of the osgEarth types as IVE.  The only thing you can do is write a MapNode to another earth file.
