Normally, camera move mode ( + and also + on the Mac) is calibrated to best view objects at the origin (the center of world space, coordinate 0,0,0). This can become awkward when you want to move the camera around objects away from the origin.
The point of interest manipulator lets you center the camera movements on a point on the model.
To use the point of interest manipulator
First, make sure the point of interest manipulator is turned on.
The General Preferences window appears.
The ViewCube is the default view control, but we will use the Viewing Panel in these tutorials. The ViewCube and NavBar provide the same functionality as the Viewing Panel. For information, see Use the ViewCube tool and NavBar.
The Viewing Panel appears in the upper left corner of the Perspective window.
The point of interest manipulator appears on the model where you clicked.
Drag with the to tumble. The view tumbles around the point of interest.
The point of interest manipulator jumps to the new point.
The manipulator moves across the surface of the object.
The arrow is light blue when it is pointing toward you and yellow when pointing away.

These arrows represent the tangents along the U and V directions of the object.
The view changes to look down the tangent in the U direction.
Use the following overview illustration as a reminder of the different controls on the point of interest manipulator.
