ABSTRACT:
A method for generating a presentation of a region-of-interest in an information representation including the steps of: selecting a viewpoint for the region-of-interest; creating a lens surface for the region-of-interest; the lens surface having a focal region and a shoulder region surrounding the focal region; creating a transformed presentation by: determining boundaries in the representation for the focal region and the shoulder region; determining boundaries on the lens surface corresponding to the boundaries in the representation by applying a distortion function defining the lens surface to the boundaries in the representation; perspectively projecting the boundaries on the lens surface onto a plane spaced from the viewpoint; and, copying information in the representation lying within the boundaries in the representation onto the focal region and the shoulder region of the lens surface using respective focal region and shoulder region stretch bit-block transfer operations; and, displaying the transformed presentation on a display screen to generate the presentation of the region-of-interest.
