Yes. To use osg::ref_ptr the object has to be derived from osg::Object.
That's where the reference count code is.

It has to be derived from osg::Referenced.

Hello,
Can you please correct any wrong statements:
1. osg::ref_ptr increments the reference count when it is constructed
with a pointer.
2. osg::ref_ptr decrements the reference count when it is destroyed
3. osg::ref_ptr::get returns a raw pointer and does not increase the
reference count
4.
Hi Chris,
In point 7, while you pass a raw Camera* to viewer.addSlave, you
will probably find that it then stores that pointer in a
osg::ref_ptrosg::Camera, which then increments the
reference count. Therefore the reference count is decremented to 1
