Can You Change 3D Object Rotation Axis?

Question

Greetings. I have created a 3d object using repousse in Photoshop (CS5 extended). The original 2d image was created in Illustrator. I have found that in both Photoshop and After Effects, when I rotate this object in 3D space, either rotating the object itself or the camera, that the axis upon which it rotates is not the 3D center of the 3D object, but rather somewhere behind it. The result is that it is rotating like the moon rotates around the earth, rather than rotating in place, like an eye moving (rotating) in an eye socket; i want the eye ball to stay in one place, but see the pupil move up and down and all around like a real eye would.
I have had no luck changing anchor points or positions of the object, even though I do have the X, Y, Z coordinates to manipulate.
Can you tell me how to adjust this anchor point, or rotation axis point, or whatever this would be called?
Thanks.

Not really true...
Yes it is limited but it can be altered.
I believe that photoshops 3d center point is based on the world center and not the objects center. This means that it is possibloe to move the object to the world center to fix the rotation of your object.
Open window>3d panel and just below the layers in that panel are some icon at the left side of the panel. Third icon down is the mesh tool, hold down the mouse button to bring up the pop up menu. Select the slide mesh tool. This will let you move the mesh adjust the pivot point.
The problem that I see with this, is that it is trial by error, I do not see away to visually see where the world center is.
Scratch that, at the bottom of the panel are three icons. The left of the three will turn on the ground plane. The plane does show world center.(where the red and green lines intersect is world zero)
To understand which axis is which, sinse it does not specify.  Select the 3d pan tool, then in the top tool bar, type in a value one axis at a time to see which direction the object is moving. Then repeat the process for the rotate tool and see how the object rotates around each axis.
