Currently, several 3D stereoscopic projection systems exist where the audience are required to wear some sort of visual aid. A number of research groups are investigating autostereoscopic displays, as these systems are more acceptable to the casual observer as they require no additional visual aids. Most autostereoscopic projection displays are stereoscopic or employ multiview techniques. Both approaches are limited in their ability to present realistic 3D images with natural viewing attributes. The paper reports on the results of experiments carried out to evaluate large-scale 3D integral projection. Two projection arrangements (single-lens un-corrected optics and double-lens corrected optics) are reported and their advantages and disadvantages described. Live capture and computer generated integral images have been projected back to “life-size.” The observer can interact with the 3D image by reaching into the presented volumetric image space.

Over the past decade there has emerged a growing number of sculptors, from around the globe, who have found a use for the computer in their research and practice. For some it offers a design tool but for others it has become a new media. A new integral imaging system capable of real-time capture and replay and methods of computer generation of synthetic integral images has recently been developed. Keith Brown, a sculptor was intrigued at the possibilities this offers as a means through which to realize cyber-sculptures as true 3D optical constructs. This paper presents the most recent results of the collaboration between Keith Brown and the Imaging Technologies Group at De Montfort University.
