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.
