I have a list called mesh_list;which is a boost::ptr_vector mesh_list; now I want to delete one element from it. inside of mesh object it has 1 pointer which I newed from constructor,they are:

texture* tex;

now it is a normal pointer, Do I have to delete it before erase the mesh element from list? what if I change the texture pointer to shared_ptr,what advantage will I get? thanks
