Method and system for displaying stereoscopic detail-in-context presentations

A method implemented by a data processing system comprising using one or more devices of the data processing system to perform acts including:

• constructing a lens having a plurality of polygonal. surfaces according to a lens function;
• and
• generating a stereoscopic presentation of a region within an information representation of a digital image, the stereoscopic presentation including a stereoscopic distortion of the digital image in the region surrounded by undistorted portions of the digital image outside of the region by:
• creating first and second transformed presentations by overlaying first and second images of the information representation of the digital image onto the constructed lens for the region, the plurality of polygonal surfaces forming a single distorted surface upon which the first and second images are overlaid;
• and
• perspectively projecting the constructed lens having the overlaid first and second images onto a plane in first and second directions aligned with first and second viewpoints for the region, respectively, the constructed lens configured to adjust in accordance with one or more signals received by the data processing system from a graphical user interface (GUI) rendered over the region.

One or more computer-readable memories storing instructions that, responsive to being executed by one or more devices of a data processing system, cause the one or more devices of the data processing system to perform operations comprising:

• constructing a lens having a plurality of polygonal surfaces according to a lens function;
• and
• generating a stereoscopic presentation of a region within an information representation of an image stored in memory of the data processing system, the stereoscopic presentation including a stereoscopic distortion of the image in the region surrounded by undistorted portions of the image outside of the region by:
• overlaying first and second images of the region within the information representation onto the constructed lens for the region, the overlaying including:
• producing the first and second images of the region;
• and
• texture mapping the first and second images to the plurality of polygonal surfaces of the constructed lens;
• and
• perspectively projecting the constructed lens having the overlaid first and second images onto a plane in first and second directions aligned with first and second viewpoints for the region, respectively, the constructed lens configured to adjust responsive to one or more signals from a (GUI) rendered over the region.
