We can go on a trip to Mars and wander through the red sand, or why not drop in on Pluto? The research project OpenSpace, led by LiU professor Anders Ynnerman, is now opening the universe for visits.

“The information comes from many different sources and arrives in many different forms. The platform we develop makes it possible to study phenomena with extremely different scales of time and space, in one unified context,” explains Emil Axelsson, research engineer at the Division for Media and Information Technology (MIT) at LiU.

He is one of the researchers developing OpenSpace, in collaboration with researchers at the University of Utah, New York University, the American Museum of Natural History, and NASA.

“We had six of them out travelling in the spring, and next year we plan to send out more. I have a Skype meeting with them once a week, which ensures that they get the supervision they need,” says Emil Axelsson.

A trip to Mars is the result of a degree project carried out by Karl Bladin and Erik Broberg, who travelled to New York and the American Museum of Natural History. This degree project resulted in a scientific article, which received the best paper award at one of the major research conferences in the field in the US, IEEE Vis.

Degree projects

The authors show in the article how to select and integrate data from several sources, and how to use visualisation methods to render high-resolution terrain models of the Martian surface. The visualisation is interactive, which means that the viewer can fly completely freely above the planet. The article describes other applications, such as the work carried out by planetary probe New Horizons, photographing the surface of Pluto.

This degree project and several others have been integrated into the OpenSpace system, which means that we can start on the Earth and explore the universe, fly by Pluto and then land on Mars.

OpenSpace is primarily a research tool, even though it is admirably suitable for visualisation in large-scale dome theatres such as Visualization Center C, in VR headsets, and on visualisation tables.

“We can visualise what we know, and we can also show how we know it,” says Emil Axelsson.

Linköping University and Visualization Center C received in January 2017 a donation of SEK 150 million from the Knut and Alice Wallenberg Foundation, which is celebrating its centenary this year. Visualization Center C in Norrköping is to use SEK 70 million to buy new computers and projectors, and to develop new content. The rest of the donation will be used to enable the productions developed in Norrköping to be disseminated to the National Museum of Science and Technology in Stockholm, Universeum in Gothenburg, the Science Center in Malmö, and Umevatoriet in Umeå, each of which has received SEK 20 million.

The project is called the “Wallenberg Immersive Science Communication Dome”, or “WISDOME”. Both WISDOME and the OpenSpace project are led by Anders Ynnerman, professor of science visualisation at Linköping University.
