Large Autostereoscopic Multiview 2D/3D Switchable Desktop Display

Scientists and engineers must view increasingly complex, computer-generated, multi-dimensional data sets, as well as simulations based on those data sets, often in collaborative environments where several researchers at remote locations are viewing the data. Such data sets are often rendered in three dimensions, and, due to their complexity, it is often necessary for researchers to view them in stereoscopic (3D) form. The sense of depth is needed to see where various points, structures, and other representations are positioned and oriented relative to one another. At present, researchers typically don commercial 3D glasses to view such representations. However, this tried and true stereo viewing technique has many limitations, including its inability to render distortion free images for more than one person in one position. Autostereoscopic (3D without glasses) displays also exist, but existing models either introduce observer position restrictions to see the images or else drastically reduce the resolution of the images to create 3D. This project will develop a high resolution autostereoscopic display that will allow several observers to observe complex data sets without distortion. Commercial Applications and other Benefits as described by the awardee The 3D display device should find wide use within the DOE and other government laboratories for a host of applications, including analysis and interaction with complex data sets; simulation of air flow through and around aircraft, vehicles, buildings, and engines; coolant flow; and government-sponsored educational exhibits/facilities. Beyond government applications, such a display should find wide use in CAD, medicine, advertising, and entertainment (eventually for home television use).
