The look at dependency graph node.
This node has all the functionality of the aim constraint node,
but additional behavior to implement the 2 and 3 node camera. The
camera view tools and manipulators are capable of disabling this
node during the mouse press and drag. Upon mouse release the
target and the up nodes will then re-positioned to reflect the
camera's new orientation.
The twist can be used rotate the camera around the viewing
direction when the worldUpType has been set to kUpScene or
kUpVector. These up settings define the 2 node camera. This
attribute has no effect otherwise.
The distanceBetween is typically connected to the camera center of
interest, and is a measure of the distance from the camera eye
point to the target.
The displayConnector attribute can be used to toggle the display
of the connection lines between the up, eye, and target nodes.
