Hi,
I am in a situation where I receive a osg::ref_ptr<Group> to which I should add
a Transform Node (or basically prepend it)
Usually the group I receive is in a hierarchy of nodes, so I was thinking about
getting parents of this group, removing this group as a child and add the
Transform instead.
But is there a better way?
Since I actually do not know anything about the parents of the group it is also
possible that there is no parent yet so the exchange is getting difficult.
Now I am wondering if it is possible and safe to swap the inner pointer of the
ref_ptr. Basically my functions looks like
Code:
void foo (osg::ref_ptr<osg::Group> myGroup)
{
// do something
osg::ptr_ref<osg::MatrixTransform> mat = new MatrixTransform;
// change
myGroup.swap(mat);
}
Which is called from a parent function like
Code:
void parentFoo()
{
osg::ref_ptr<osg::Group> myGroup = new osg::Group;
foo(myGroup);
// now I need myGroup to point to MatrixTransform without noticing it
}
Is this going to work?
I have no compiler on this maschine to test right now so I am just assuming and
browsing the docs.
Thank you!
Cheers,
Sam
