Finding your way in Cyberspace

13.12.2006
The three-dimensional computer programs of the future will give the ability to see through walls and objects just like Superman.

This is shown in a dissertation by Niklas Elmqvist at Computer Science, Chalmers. He has also developed new methods for guided sightseeing in the 3D-world.

Three-dimensional computer environments have great potential for entertainment, education and simulation of activities that are either too difficult or too expensive to perform in the real world.

However, one problem with computer-based 3D environments is that it is easy to lose track of where you are and where you are going. In his dissertation, Niklas Elmqvist presents new methods designed to help the user effortlessly understand and move through this type of complex 3D environments.

This is achieved by taking advantage of the visual cues that we humans normally make use of to perceive our surroundings, such as size, shape, and motion.

Beyond X-ray vision and automatic sightseeing tours, he introduces a method where the user is equipped with a special force field for pushing away objects that get in the way.

Niklas Elmqvist also describes in the dissertation methods for graphically showing a course of events. These methods can be used to trace complex chains of cause and effect for such examples as large computer networks, like the Internet, biological processes, or advanced mathematical problems. The methods have so far been applied to visualization of scientific articles to help show how ideas and trends appear and develop.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
