示例1: vp
void
KML_Feature::build( const Config& conf, KMLContext& cx, osg::Node* working )
{
KML_Object::build(conf, cx, working);
// subclass feature is built; now add feature level data if available
if ( working )
{
// parse the visibility to show/hide the item by default:
if ( conf.hasValue("visibility") )
working->setNodeMask( conf.value<bool>("visibility",true) == true ? ~0 : 0 );
// parse a "LookAt" element (stores a viewpoint)
AnnotationData* anno = getOrCreateAnnotationData(working);
anno->setName( conf.value("name") );
anno->setDescription( conf.value("description") );
const Config& lookat = conf.child("lookat");
if ( !lookat.empty() )
