[osg-users] pfObject::getNamedUserDataSlot

[Robert Osfield]

Hi Tony,

As Nick says there is the Node::setUserValue(..) template method and
Node::setUserData().  When you use UserValue it creates a UserDataContainer
to hold the values in a vector of osg::Object*, so this UserDataContainer
kinda has "slots".  The UserDataContainer is only created on demand and
when it is used it attached to the Node(or any osg::Object) via the
setUserData().

Another approach you could take it is create your own version of
UserDataContainer that uses a map rather than a vector and attach this as
UserData.

As a general note, the OSG is designed to be extensible and configurable,
while Performer is just configurable.  In Performer you have few options to
do things that aren't originally anticipated by the API, but with the OSG
the door is open to doing completely different things with it.

Robert.
