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.
If only the three little pigs had these options for their houses. As homeowners collect insurance money and other funds tied to storm recovery, three alternative building systems are beginning to gain attention - modular, concrete and steel framing. "These options will catch on," said Toni Wendel, president of the Home Builders Association of Greater New Orleans. "New Orleans is ready for some new ideas as long as we can keep our neighborhoods, our city, looking like our neighborhoods, just better and stronger." Building companies, already beginning construction or contracting with neighborhood groups to build homes, are using the three models. "Modular is quick and it's coming," Wendel said. "We didn't have the labor trained to use the steel and concrete but they're now working with us to teach about using those materials." Modular versus manufactured The issue is what's modular and what's manufactured.
