University Jaume I researchers at work on EU project to improve video game realism


A group of researchers from the Department of Computer Languages and Systems at the Universitat Jaume I is taking part in a project to improve realism in video games. The goal is to design software that makes the task of game programmers easier so that they can create more credible environments without having to carry out complex operations. The research, which has received financial help of 1,649,000 euros from the European Commission and is to last for 33 months, involves 11 other members from Spanish and European universities, and from companies from this sector.

So far, game design has not presented any special difficulties for companies because the techniques used have been somewhat rudimentary. Nowadays, however, the need to improve video game realism requires more complex applications. The UJI and the other universities involved will work on turning the complex formulas already existing in the laboratory into usable programmes that will improve the degree of realism in three basic aspects: geometry, lighting and visibility.

”Our idea is to develop the technology that was used in very complex workstations so that it is immediately accessible on PCs or on low cost platforms”, explains Miguel Chover, responsible for the project at the UJI. “Our objective is to create software so that video game programmers can simplify their tasks and work with more complex models and more realistic lighting techniques without having to develop their own algorithms. That is, what we do is a sort of algorithms bookstore”, added Chover.

The University of Girona, together with the University of Budapest, will be in charge of improving video game lighting; the University of Vienna will work on visibility; and the Universitat Jaume I de Castellón, the Polytechnic University of Valencia and the University of Limoges will improve the realism of the geometry of the objects on screen and their movements.

”We work with multiresolution models, which are a tool that allows the programmer to change the level of detail automatically. In this way, a designer designs a character, the programmer captures it and puts it into our algorithm data structure. It then automatically changes its level of detail without the programmer having to generate the algorithms. This is all done while at the same time the transition of geometry is made smooth so that everything is more realistic and jumps do not occur when a character goes from a more distant to a nearer plane”, explained Chover. The applications concerning lighting and visibility will have the same effects.

Companies from the videogame and the virtual reality sectors, and the Research Association from the Toy Industry are also taking part in the project. The role of the companies is to expose their needs and test to see whether the solutions provided by researchers are well adapted to the applications in the world of industry.

In Spain, 47% of the population between 13 and 34 years old are habitual video game users, a percentage which can be seen in the income level of the industry. Last year this sector had a turnover of 800 million euros with a 12% growth, whereas the cinema box-office takings was 636 million, an increase of only 2%.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
