Hi Roni,
Thanks for the modified example. I much prefer avoid use of globals
so have modified the code to get the scene graph from the view, so the
code now looks like:
if (ea.getKey() == 'o' )
{
osgViewer::View* view = dynamic_cast<osgViewer::View*>(&aa);
osg::Node* node = view ? view->getSceneData() : 0;
if (node)
{
osgDB::writeNodeFile(*node, "hud.osgt");
osgDB::writeNodeFile(*node, "hud.osgb");
}
return true;
}
With this I am able to see the bug with writing out the hud.osgb, but
it works fine with hud.osgb. Curiously if I do a:
osgconv hud.osgb hud2.osgt
The resulting file is almost identical to hub.osgt (only difference is
the root node name for the filename) and it works fine too. So
something in the osg::Camera set up looks to be the issue. It's a bit
odd for sure, setting a property to the same value shouldn't change
the overall behaviour, so I wonder if perhaps the defaults for the
serializer might be different from the default for osg::Camera.
Robert.
