Oddly enough, "osgt" also gives me the binary format, even when serializing
objects from the core library, e.g.:
osg::ref_ptr<osg::Node> test = new osg::Node;
std::ostringstream sstream;
osgDB::ReaderWriter::WriteResult wr
=
osgDB::Registry::instance()->getReaderWriterForExtension("osgt")->writeObject(*test,
sstream, 0);
std::cout << sstream.str() << std::endl;
Results in output:
í♫ælEE¹→♥ _ ☺ 0 osg::Node☺ ☻ ☺
However, e.g.:
osg::ref_ptr<osg::Node> test = new osg::Node;
std::ostringstream sstream;
osgDB::ReaderWriter::WriteResult wr
=
osgDB::Registry::instance()->getReaderWriterForExtension("osg")->writeObject(*test,
sstream, 0);
std::cout << sstream.str() << std::endl;
Results in output:
Node {
nodeMask 0xffffffff
cullingActive TRUE
}
Which is what I want, but for my custom object. With that, I get equivalent
results in the first case and nothing in the second.
(I am using OpenSceneGraph 3.1.4, if that matters.)
Cheers,
Peter
