1. A method of traversing a three dimensional image, performed by a computer, comprising creating an interest center-point in the image; creating a start point in the image; creating a potential function, wherein the potential function creates a potential field and guides traversal from the starting point to the interest center-point; adjusting the potential field to comprise a sum of potential fields directed toward the center-point wherein each potential field corresponds to an image; and displaying images in the potential field at intervals in the traversal from the start point toward the interest center-point.
