Hi Daniel, >> Set a watchpoint on the memory address of the _refCount member of this particular geometry object.
your idea seems very good but i don't know how to watch a specific memory address in visual studio. if you know could you tell me because i could not find. ---- Hi Ümit, actually i have a terrain. terrain has a geode and geode has a geometry. i create geometry => refCount = 1 i add it to geode => refCount = 2 i add geode to scene => refCount = 2 application runs.. i see terrain on runtime or when i want to delete, i check geometry refcount and see refCount = 3 i remove geometry from geode => refCount = 2 i set my osg::ref_ptr to NULL =>refCount = 1 and my geometry did not deleted... when should it be deleted??
