World's Largest 3D Display Screen Created with Mathematica
X3D Technologies GmbH, the leading creator of "glasses-free" 3D
display screens, uses Mathematica for almost all of its product
development. The company recently designed a 3D projection wall
display with a diagonal screen size of over 15 feet (4.5 meters),
which is believed to be the world's largest ever and has been featured
in the 2005 World Exposition in Aichi, Japan. Mathematica was
essential to the realization of this technological breakthrough and
the timeframe in which it was accomplished.
"Glasses-free" 3D means that viewing aids such as glasses or
virtual-reality helmets are not needed--the lifelike images can be
seen by the naked eye at wide viewing angles and arbitrary positions.
These stereo images consist of multiple, layered, 2D images
or perspectives, and a key problem is to find the best distribution of
perspectives that correspond to create a high-quality 3D
visualization. Mathematica enables X3D Technologies GmbH to study the
optical properties of these 3D images and systems, and to quickly check the
effects of possible modifications. It also allows development and
testing of the proprietary algorithms the company uses to produce 3D
X3D Technologies GmbH 3D screen with 183-inch diagonal.
"The success of our 3D-display technology was due to
using Mathematica from the beginning," said Dr. Ingo Relke,
author, developer, and manager of the 3D projection system. "The
combination of symbolic and numeric evaluations with the ability to
produce image processing has allowed us to obtain fast, high-quality
results and correctly inform the direction of subsequent development."
The creation of a large-scale glasses-free 3D display has very
exciting implications for future projects in a broad array of fields,
including the computer and film industries, engineering, and
environmental sciences, to name a few. X3D Technologies GmbH also
produces and tests other
screens--all developed using Mathematica evaluation technology--ranging in
size from ones for cellphones and PDAs, to midsize screens for
medical imaging and gaming devices, to larger LCD and plasma screens
of up to 50 inches for advertising and entertainment purposes.
