Hi Norm,
root->addDrawable (shape1); and root->addDrawable(shape1.get ()); are
equivalent. The bare shape1 argument will be implicitly converted to
Drawable *.
http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00319.html
The osg::Referenced objects store their own reference count (intrusive
reference counting), unlike std::shared_ptr where the reference counts
are stored with the smart pointer.
i.e., root->addDrawable (new ShapeDrawable ()); will not result in a
memory leak either.
Regards,
Judson

Hi,
In the excellent Beginners Guide, there is this code snippet (page 64):
Code:
osg::ref_ptr < osg::ShapeDrawable > shape1 = new osg::ShapeDrawable;
osg::ref_ptr < osg::Geode > root = new osg::Geode;
root->addDrawable( shape1.get() );
However, I would think the last line should be
Code:
root->addDrawable( shape1 );
to properly manage the memory.
??
Thank you!
Cheers,
Norm
PS I had to put spaces around the angle brackets. Otherwise, they would not
appear in the post.
