has been raising some interest lately in their spherical display.
In the roughly 10-inch diameter sphere, data is displayed using their volumetric 3-D display technology.
The display allows for 360-degree all-around viewing for multiple people. Recently, the US Army Research Lab has undertaken a project
to determine the potential for the technology in the military simulation field.
There are several basic volume rendering methods. Actuality Systems uses a translucent screen, spinning at 730 rpm onto which 2-D slices of the 3-D model are projected. The result is a convincing, interactive, colorful 3D image that can be seen from any angle in the room.
Currently, displays such as this one cost around $50,000 US. However, as the cost drops, we may begin to see this technology in CFD visualization.
