Detailed Description

An update callback to manipulate a node during scene-graph updates.

This update callback is used to animate a tank-barrel by angling it over time. This callback should only be applied to a DOFTransform representing the barrel of a tank. During each update, this callback sets the pitch of the DOFTransform so the barrel appears to pitch up/down.
