Construction Equipment Design and Development

Full-Scale Virtual Reality System at Large Construction Equipment
Manufacturing Site Begins Operation

FREMONT, Calif., Jan. 14, 2013 (GLOBE NEWSWIRE) -- SGI (Nasdaq:SGI), the
trusted leader in technical computing announced that SGI Japan, Ltd.
(Headquarters: Shibuya-ku, Tokyo; president: Ryutaro Ishimoto) and Komatsu
Ltd. (Headquarters: Minato-ku, Tokyo; president and CEO: Kunio Noji) have
installed a four-screen virtual reality system at Komatsu's Ibaraki Plant
(Hitachinaka-shi, Ibaraki Prefecture) for the design and development of
construction equipment. Installed at a modeling facility within the Ibaraki
Plant, the system has begun operation.

Komatsu completed its Ibaraki Plant in January 2007 as a manufacturing site
for large construction equipment. The plant develops dump trucks and other
large wheeled construction equipment used primarily in the mining industry and
exports most of its products overseas. The increasing volume of build-to-order
production for overseas markets has created the need for efficient design and
development processes. The full-fledged virtual reality system installed by
Komatsu utilizes large-screen stereographic projection to facilitate
sophisticated evaluation of equipment operability, maintainability, and other
design features, thereby enhancing and accelerating the plant's development

The four-screen immersive virtual reality system creates a virtual environment
in which designers experience how drivers and maintenance personnel actually
operate inside the equipment. Equipment design is evaluated through the
three-dimensional projection of life-sized objects. Driver visibility can be
tested in all directions and other key safety aspects can also be tested and
validated. Equipment designers of pump and engine components can also achieve
the sensation of handling real physical parts, enabling them to accurately
study the maintainability and ease of making routine repairs. A key feature of
the system is the ability for third parties to use a separate monitor to
independently confirm how drivers and maintenance personnel move and see
within the equipment, as well as the movement of the equipment itself.

The large-scale virtual reality system is comprised of front, right, left, and
floor screens, four projectors from U.S.-based Christie Digital Systems, and
six optical motion-capture cameras from Germany-based ART. With screens
measuring 3.8 meters wide and 2.4 meters in height and depth, the system can
project life-sized images of large-scale equipment.

Four SGI Japan Asterism visualization systems featuring NVIDIA's
highest-performance GPUs are used for three-dimensional visualization
processing, and TechViz XL software from the French company TechViz is used
for the automatic three-dimensional display. This enables the PC-generated CAD
models to be shown in a virtual reality environment without the need for
conversion processing. Once CAD data has been created, the models can be
quickly displayed through the system.

Komatsu began adopting 3D CAD systems for construction machinery and vehicle
design and development in 1996. In 2004, the company began developing all new
equipment models on 3D CAD systems. However, Komatsu still found a significant
gap between designs on PC displays and real equipment when it came to
visibility, safety, maintainability and ease of repairs. This gap created the
need for a system that could provide sophisticated evaluation capabilities
through large screens and 3D projections. Komatsu installed its first
four-screen virtual reality system at its Osaka Plant in May 2011. In 18
months, the system has generated a wealth of benefits, including reduced
development times and modeling costs. The Ibaraki Plant installation
represents the company's second full-scale virtual reality system.
