VTT has developed a stereo picture application

07.02.2007
The new 3D technology gives old games a new lease of life

VTT Technical Research Centre of Finland has developed a stereo picture application for 3D games. The new plug-in, registered as "StereoGames", transforms the existing 3D game to a stereo game that utilizes the stereoscopic vision - even though the game didn't have this feature originally. The new depth dimension gives the old games a new lease of life, thus eliminating the need for investing in a completely new game.

The easily installable plug-in is suitable for PC games, mobile phone games, game consoles, digital television applications, animations and online games. Negotiations with several software development companies have already begun, and the launch of StereoGames for PC games is expexted within the next year. This plug-in makes it possible to add stereo information to mobile phone camera pictures, too.

VTT's Stereogames has the unique feature that it can transform the existing 3D game into a stereogame that has a clear depth effect. Usually, the stereo effect is incorporated to a game or a video during the production phase, like in the popular Shrek3D video. The StereoGames application does not have to be installed in the game, and no laborious installation manoeuvres are needed; the application automatically handles all required actions. The stereo effect can be viewed by using filter glasses or shutter glasses, or, depending on the application and device, even without glasses. The most affordable option is filter glasses, costing approximately EUR 0.35.

There are several different techniques for producing stereo pictures.
The method developed by VTT uses the so-called anaglyphic technique. The advantage of this technique is that it does not require heavy and expensive peripherals for viewing. The anaglyphic technique is a filter technology that builds on the complementary colour scheme. This means that two differently coloured images are produced, one for each eye. As the viewer looks through the filter glasses, the brain fuses the images into a three-dimensional stereo composition. The depth perception effect enlivens the game, making it more exciting: the atmosphere of the game is very realistic and the player can outline and estimate dimensions better than before. The improved spatial impression also adds to the attractiveness of the game. The best applications for the technology include game consoles as well as online and PC computer games because larger screens provide a more efficient stereo effect.

VTT's patented StereoGames method with stereo pictures offers numerous prospects for development. The method can be used in all 3D applications with a changeable angle of view for producing stereo pictures; therefore, architecture, product design and molecular modelling, to name a few, can greatly benefit from it.

The code corresponding to the StereoGames technology has been licensed for Mobile Solutions in Italy since the beginning of 2006, in connection with VTT's "Pingis" game. "Pingis" is a two-player game for mobile camera phones. The game also allows a single-player game. The phone's camera senses the movement of the phone on the basis of the picture and transforms it to a racket's movement. The stereo effect enhances the perception of depth, and the player can better perceive the dimensions

and distances of the table.

Stereo pictures or video clips by a camera phone

VTT's patented technology description also includes, among other things, the StereoImaging technology. This technology means that a frame or a video clip recorded by a camera phone could be submitted to a service provider's server for "stereo picture development" by using one button. Once developed, the stereo picture could be sent back to the photographer or to a designated number or Internet address. The picture could also be downloaded onto a PC computer for optimal viewing. To take an example, a real estate broker could take a video clip of an apartment and submit it and all the necessary information to the desired online service using a mobile phone. The clip could be automatically generated as a stereo clip on the Web page.

VTT is planning to start a project to develop the StereoGames technology for autostereoscopic displays to completely eliminate the need for glasses. An application based on the StereoGames technology would bring the stereo dimension used in 3D games and other 3D applications to autostereoscopic displays - affordably and easily.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
