1. A method of traversing a three dimensional image 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 comprises 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.
