Floating 3-D display seemingly out of sci-fi

摘要

Actuality Systems Inc., Reading, MA, has revealed the latest version of its "science fiction" like floating 3D display technology that could revolutionize the future of design engineering, pharmaceutical design, and medical imaging, among other potential applications. Actuality's autostereo-scopic volumetric display makes 3-D images appear to float inside a special viewing dome that can be inspected 360° around the display without the use of special goggles (Fig. 1). The display seems to act as a "crystal ball" for a computer; it accepts 3-D data from standard sources and converts it into volume-filling imagery that can be seen from any angle.
