Abstract
A method for generating a presentation of region-of-interest in an information representation including the steps of: selecting a viewpoint for the region-of-interest; selecting a location for the region-of-interest; creating a lens surface having a predetermined location for the region-of-interest; creating a transformed presentation by: determining a mapping for pixel coordinates from the representation to the lens surface by applying a distortion function defining said lens surface to said pixel coordinates; calculating a vector from the predetermined location to the location; and, copying pixel information from the representation to the lens surface according to the mapping as displaced by the vector; and, displaying the transformed presentation on a display screen to generate the presentation of the region-of-interest.
