Re: [osg-users] use of ref_ptr

I think the best practice is to only use the ref_ptr structure to refer to objects derived from Referenced as you said. But you can get away with using bare pointers whenever you know you're going to do some operation that will increment the ref count anyway, ex. adding it to an existing group.

Other people who know more about this than me may tell me I am wrong, but here is a simple rule of thumb I have used. If the pointer is going to be saved for later use (i.e. class member, static variable, etc.) then it needs a ref_ptr. If you are just going to create a local variable, add it

Re: [osg-users] use of ref_ptr

Another thing I believe is often overlooked is using ref_ptr's with objects who attempt to properly support copy construction. It's such a hard thing to get right that I plan eventually adding a chapter about it in the osgWidget docs, when the time comes. It's not uncommon to want to keep
