SANTA MONICA, Calif.--(BUSINESS WIRE)--Dec. 15, 2003

DDD Group Plc. (LSE:DDD):

-- The amira(R) Data Visualization Application from TGS Run on a

Sharp Actius RD3D Notebook with DDD's TriDef(TM) Visualizer 

OpenGL(R) Software Allows Users to View Their Data in 3D

without the Use of Stereo Glasses

TGS is proud to announce a marketing agreement with DDD Group Plc. ("DDD") (LSE:DDD) and Sharp Systems of America ("Sharp") that will position the amira(R) data visualization application as the premier 3D data visualization solution for users of Sharp's revolutionary new Actius RD3D notebook PC.

The combined solution of amira and TriDef Visualizer allows Actius RD3D customers with libraries of existing 3D visualization data sets to rapidly take advantage of the 3D display capabilities of the Sharp Actius RD3D.

amira is TGS's flagship 3D analysis and visualization application package offering the end-user innovative capabilities to easily and interactively analyze complex 3D data sets. Fast, reliable and easy to use, amira is the State-of-the-Art three-dimensional visualization software product offering unparalleled techniques for creating complex data visualization. Included in these techniques are direct volume rendering, iso-surfaces, innovative vector field visualization tools, image segmentation, surface reconstruction, surface simplification, and generation of tetrahedral grids. amira is the perfect tool for researchers working in confocal microscopy, biology, neuroscience, medical imaging, medical simulation, geosciences, oil & gas, FEM, CFD, and 3D data visualization. As with all TGS products, amira is cross-platform compatible and will run on Windows(R), UNIX, IRIX, Solaris, Linux(R) and 64-bit Linux on the Itanium2(TM) platform.

"The partnership with DDD and Sharp has the potential to bring glasses-free 3D visualization to the masses," added Steve Lutz, VP of Sales/Marketing for TGS. "Allowing the scientist to immediately see his data in 3D in amira(R) on their Sharp Actius RD3D notebook is a tremendous step in making 3D visualization a common tool in any industry where data visualization is needed."

"Sharp is pleased to be working with TGS, as Sharp's 3D Display solution will bring a greater level of visualization to TGS's amira customers, allowing faster understanding of complex medical imagery and faster diagnosis," said Ian Matthew, 3D Business Development Manager, Sharp Systems of America. "These advantages are also beneficial for other vertical market users of amira, and with portability offered by the Sharp Actius RD3D, users can now work better collaboratively."

"Using amira(R) on the new Sharp Actius RD3D notebook, DDD can offer support to a broad range of popular 3D visualization datasets that allows us to address a wide variety of prospective business applications and users," said Robert Mannino, VP Visualization Solutions for DDD, "and the Sharp Actius RD3D notebook delivers a mobile solution which has not been available before to users with 3D glasses."

The new Sharp Actius RD3D notebook is the world's first notebook computer that incorporates Sharp's TFT 3D LCD technology, which makes it possible to view eye-popping 3D images using the naked eye, but is easily switched back to 2D viewing for standard applications such as spreadsheets, photo editing or email. With uses ranging from CAD and other design applications, drug discovery, medical imaging, mapping/GIS, oil & gas, entertainment, advertising, broadcasting, electronic books and a vast array of other vertical markets, the Actius RD3D makes possible a range of new applications providing three-dimensional images with an enhanced level of visual ambience and detail.
