San Jose, CA -- September 23,1992 -- StereoGraphics Corporation, the
world's leading supplier of true three-dimensional electronic stereoscopic
display products, today announced that it will offer its CrystalEYES VR
bundled with WorldToolKit from Sense8 Corporation, Sausalito, CA.

CrystalEYES VR is a stereo 3D viewer and head-tracking system that permits
users to view and interact with three-dimensional spatial information on a
workstation monitor. WorldToolKit is a software toolkit that enables a
developer to rapidly build real-time graphics simulations and
virtual-reality (VR) applications.

The announcement was made at Virtual Reality 1992, held at the Fairmont
Hotel, San Jose, California, Sept. 23-25. CrystalEYES VR and WorldToolKit
are being demonstrated in the StereoGraphics booth, #501 and the Sense8
booth, #402.

"StereoGraphics and Sense8 offer developers the top VR software and
hardware solutions at the best possible price, demonstrating that the best
strategic alliances are formed by the market leaders. This is most
important to developers in the dynamic VR industry, where the best
solution tools are now available to help them meet market demand," said
Wil Cochran, StereoGraphics' vice president of sales and marketing.

"The combination of WorldToolKit with CrystalEYES VR enables developers to
build powerful virtual world applications with high-resolution, full-color
stereoscopic images," said Tom Coull, president of Sense8. "WorldToolKit
has been accepted as the application programmer's interface (API) of
choice for both monitor-based and immersive virtual reality systems."

CrystalEYES VR systems produce a true 3-D image on projection screens and
computer monitors. The patented CrystalEYES eyewear alternate left and
right images at 120 frames per second, thereby creating true flicker-free,
full-color depth perception. Additionally, the stereo image interacts via
an ultrasound head-tracking device creating six degrees of freedom. The
viewer interacts with the image through head movements while viewing in
true 3-D, creating a startling visual experience.

CrystalEYES VR is also available in a version that permits total immersion
in an environment of the user's choice. He can participate with or without
others during the experience, as displayed at Siggraph '92 by the CAVE, a
high-resolution virtual reality experience created by The University of
Chicago in collaboration with StereoGraphics.

WorldToolKit is a set of C functions that enables a developer to rapidly
build real-time graphics simulations. Its elegant design makes
interactive, three-dimensional graphics applications easy to prototype
while providing the functionality required to build complex applications.
A key feature of WorldToolKit is its hardware-independence. For example,
source code written for the PC will compile on the Silicon Graphics
SkyWriter. This support for cross-platform development gives a
WorldToolKit developer significant flexibility and expandability.

Availability and Pricing. The bundled products are available now directly
through StereoGraphics and Sense8. Customers will receive a 15% discount
off the regular list price of both products. The bundled products are
initially available on Silicon Graphics Indigo workstations for $7900.

Sense8 Corporation was incorporated in January of 1990 as a software
company dedicated to providing affordable real-time 3D graphics for the
interactive visualization and simulation of data, designs, concepts, and
physical systems. Sense8's product, WorldToolKit, was born out of the
desire to provide a powerful yet easy-to-use software system accessible to
a wide range of users. WorldToolKit is available directly from Sense8 as
well as from a worldwide network of distributors in the U.S., Japan, the
U.K., France, Germany, Italy, and Finland. Sense8 can be reached at 4000
Bridgeway, Suite 101, Sausalito, CA 94965. Tel: 415/331-6318, Fax:
415/331-9148.

StereoGraphics Corp., founded in 1980 and now the world's leading
manufacturer of true stereo viewing systems, invented and developed the
market for modern electro-stereoscopic displays. CrystalEYES VR
workstation-based products as well as its complete line of compatible
stereo large-screen projection and stereo video camera system products are
available directly from the company. Due to its capability and reasonable
price, the CrystalEYES VR stereo viewing system has been accepted as
breakthrough hardware technology for virtual reality viewing.
StereoGraphics is located at 2171 East Francisco Boulevard, San Rafael,
California 94901, phone 415/4594500, Fax 415/459-3020.
