A true 3D display has been a dream of many for years. Although various three-dimensional technologies have been developed in recent years, few are able to display real time 3D images and video from any angle in the same way an object would appear to us in the real world. This article will present one such technology called Perspecta and explore its current and future capabilities and uses.
About four years ago, I reviewed a fascinating display called the Perspecta Spatial 3-D System, which was developed by the Massachusetts-based company Actuality Systems. Perspecta is a true three-dimensional display that allows users to view moving objects from any angle with the unaided eye, simply by walking around them as you would if you were looking at real 3D objects. Perspecta consists of a rotating round white polymer screen resting on box containing software, hardware, and an optical system. Moving images that seemingly float inside a crystal ball-like structure are generated by slices of successive 2D images, rapidly projected one after another onto the screen, creating an illusion of a real 3D image.
