Hi Ufuk,
thank you for your attention.. :)
actually i didn't know that it is deleted on "suitable time". i always
expected it to be deleted when i set to NULL.
Perhaps it's as simple as: the render back-end had a ref_ptr to your
geometry because it was busy rendering it. So when you set your pointer
to NULL, the ref count went down to 1, and at the end of rendering the
current frame the render back-end released all its ref_ptrs and your
geometry was deleted.
Also, search the archives, I have posted a while back a modification to
osg::Referenced that allowed you to have certain functions called each
time a ref_ptr increments or decrements its reference count, along with
Win32 functions that captured the call stack at that point. I had
developed it as a way of tracking a memory leak that was caused by
circular ref_ptrs. The modifications in question were not general enough
to be integrated (in particular they had no Linux/MacOS X
implementation), but they were certainly useful for me, and it could be
instructive to you if you want to know exactly who has each reference to
your object.
Hope this helps,
J-S
