Wisdome

Wisdome has its starting point in the world-leading visualization research conducted at Visualization Center C and Linköping University. With a contribution from Knut and Alice Wallenberg's foundation, we are now scaling up a national effort.

The new experience arenas in the form of labs and theaters, take visitors to places we could never reach ourselves, let us see what would otherwise be hidden from us and create an understanding of events that are too small, too big, too fast or too slow for the human to overview.

Scientific visualization is a huge opportunity to make complex research accessible to everyone.

Within Wisdome, Sweden's five leading science centers and several universities and research environments collaborate around research, technology, application and didactics for new ways of learning and engagement. Techniques and methods that provide completely new opportunities to develop learning and problem solving.



UPGRADING The Dome

The dome theater at the Visualization Center C in Norrköping is classified as one of the world's most technologically advanced, after an extensive upgrade at the beginning of 2019. The new projectors have the designation 6P, which means they handle 6 different primary colors of lasers; 2 red, 2 green and 2 blue representing different wavelengths of the visible spectrum. Thus, we can show two different images on the dome screen at the same time, and our new 3D glasses are designed so that one image is visible through the left lens and the other through the right. The big difference compared to before is that we get much less loss of brightness in the new glasses, which makes the image much brighter and sharper.

RGB (Red, Green, Blue) is the model we use today to produce all colors on a screen or with a projector. Our projectors are called RGB lasers, as they consist of red, green and blue laser banks. Nowadays it is unusual to have pure laser for all these primary colors in a projector, but this means that, unlike a lamp that shows white light, the entire brightness of the projector can be used to produce the correct colors, giving an incredibly bright and colorful image.

The projectors are significantly more powerful than before, with a brightness of up to 30,000 ANSI lumens, and run at a high resolution (4096x2160) per projector as well as a high refresh rate (120Hz), and these factors contribute to a detailed and sharp image. When the image from the 6 projectors overlaps, the resolution becomes 8K.

The only disadvantage of the new projectors is undoubtedly their size, as they are about 1.5m long and weigh about 250 kg each. And in addition to this, each projector is connected to an external liquid cooler of approx. 100 kg which only cools the lasers inside the projector. The advantage of external liquid cooling is that we have strategically placed these outside the judgment to have a quiet environment, but also recover the heat in a better way.

Background

Wisdome has its starting point in the world-leading visualization research conducted at Visualization Center C and Linköping University. With a contribution from Knut and Alice Wallenberg's foundation, we are now scaling up a national effort. The vision behind the Wisdome project is big; to reach millions of school children and students through immersive scientific communication throughout Sweden. How? By upgrading the current court at Visualization Center C in Norrköping and establishing four new courts in Gothenburg, Malmö, Stockholm and Umeå.

Productions

Within the framework of the project, there is a long-term goal to produce five new court performances, with a wide range of scientific topics, at Visualization Center C in Norrköping. Even today, dome shows are produced with 3D films and software for real-time viewing. Through a close collaboration with e.g. NASA now has the ability to make flights in our solar system and carry out real-time landings on Mars, using actual 3D images that are updated continuously. It is also possible to fly over Pluto and visit other places in the known universe. Through these immersive experiences, we can create an interest in science and technology in future generations.
