Christie projectors help display the high-precision mapping of the Global Shift

In the exhibition held at the Ars Electronica Center, two 4K7-HS projectors have been used, five Captiva DHD410 and one 4K10-HS. To these are added three LCD laser equipment LWU650-APS.

The Global Shift Exhibition, that is being exhibited in the Ars Electronica Center (Austria), has deployed a wide selection of Christie projections to examine the influence of the technological process on natural living environments.

The exhibition uses models and projections to show the changes that digital progress has imposed on the world and in the way of contemplating it.. Through digital infrastructure, Earth observation with satellites or daily data recording, the exhibition makes us reflect on the current conditions of our environment.

In collaboration with the partner of Christie, Ton & Bild Medientechnik, Ars Electronica selected a 4K10-HS projector, two 4K7-HS and five Captiva DHD410. All 1DLP models. To these are added three LCD laser equipment LWU650-APS.

The satellite images provided by different institutes and organizations were reflected in several elevation models for whose mapping precision the Christie Twist Pro solution has been used., which has made it possible to map the terrain (In and around Großglockner) of great precision, in a small space and with 4K resolution.

"We are currently working with Christie HS Series projectors on the digital lift models in Upper Austria., In and around Salzburg, and Großglockner. But also, a projector from that same series is being used in Séan Doran's Orbit – A Journey around Earth in Real Time installation. We connect projectors with DP fiber optic extenders 1.2, guaranteeing its maximum resolution of 3,840×2.160 pixels to 60 Hz", explains Patrick Müller, Technical Director of Ars Electronica Solutions.

Facilities, controlled with touchscreen interfaces, they show and hide the various animation layers of the terrain models and even combine them.

Christie BoldColor Technology, integrated into the HS Series, ensures a spectacular result and helped the organizing team in choosing which projectors to use. To this is added the low noise level and its long life, a key factor since they have to operate continuously six days a week.

"We tested several projectors using techniques such as 4K pixel shifting/eShift. (pixel offset) and Christie's 1DLP projectors came out on top", comments Patrick Müller. "In addition to, with laser lighting source there is no problem to achieve the desired result, even if they have elapsed 10.000 or 20.000 hours".

It should be added that several of the exhibits had special characteristics that required customization.. "For example, a wall lift model is tilted in two directions. Positioning the projectors with the precision necessary to minimize or optimize the shadow areas and the positions of the spectators was all a scientific boast", clarifies Müller.

The flexibility offered by projectors with 360º installation option proved to be useful in this case.

After eight months of testing, creating content and implementing projects, Müller, his team members and artists were very impressed by the light power of the projectors in a relatively dark environment.: "The results and the resolution were extraordinary., especially in the case of the Großglockner digital lift model, created in 4K resolution with a width of only 1,77 meters".
