VR Interfaces: Perspecta

Overview of Perspecta
The Perspecta display system was released by Actuality Systems in May 2005. Its intended purpose is as a 3D volumetric display capable of projecting a virtual object right in front of you.

Although it looks like a hologram, this image is actually generated by a rapidly spinning display dome, operating at 720 revolutions per second. This is fast enough to provide a flicker-free image from any angle, and is enclosed in a clear outer dome, to protect your hands.

Perspecta was designed with medical or military data in mind. The display system contains a great deal of heavy duty 3D processing hardware within its housing, and is capable of absorbing up to three gigabytes of 3D data per second.

Any 3D model going into the display unit is analysed internally, and broken down into a collection of 2D stills, each of which is viewable from a slightly different angle. The result is a perfect 3D representation you can walk around, peer over the top of, or look up at from slightly underneath. For medical diagnosis - such as the heart valve taken from a patient's MRI data, the value is clear.

The display is crisp and bright; the human eye is easily able to make out the 3D objects on display even in full daylight, Any source of data can be used, so long as it is OpenGL compatible the system will accept it. This means for medical imaging MRIs, CAT scans, 3D ultrasound and PET scans are all compatible with the system, as are many military visualisation systems, and a majority of general virtual objects in all varieties of format.
