This paper describes a simple 3D display that can be built from a tablet computer and a plastic sheet folded into a cone. This display allows viewing a three-dimensional object from any direction over a 360-degree path of travel without the use of special glasses. Inspired by the classic Pepper’s Ghost illusion, our approach uses a curved transparent surface to reflect the image displayed on a 2D display. By properly pre-distorting the displayed image our system can produce a perspective-correct image to the viewer that appears to be suspended inside the reflector. We use the gyroscope integrated into modern tablets to adjust the rendered image based on the relative orientation of the viewer. Our particular reflector geometry was determined by analyzing the optical performance and stereo-compatibility of a space of rotationally-symmetric conic surfaces. We present several prototypes along with side-by-side comparisons with reference images.
