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

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

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 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 the way we view 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 & Image media technology, Ars Electronica selected a 4K10-HS projector, two 4K7-HS and five Captiva DHD410. All of them 1DLP models. To these are added three LWU650-APS LCD laser equipment.

The satellite images provided by different institutes and organizations were captured in several elevation models for whose mapping precision the Christie Twist Pro solution was used., which has allowed a mapping of the terrain (Großglockner and surroundings) high precision, in a small space and with 4K resolution.

“We are currently working with Christie HS Series projectors on digital elevation models in Upper Austria, Salzburg and surroundings, y de Großglockner. But also, a projector from that same series is being used in the installation Orbit – A Journey around Earth in Real Time by Séan Doran. We connect the projectors with DP fiber optic extenders 1.2, guaranteeing its maximum resolution of 3,840×2.160 pixels to 60 Hz”, explica Patrick Müller, technical director of Ars Electronica Solutions.

The facilities, controlled with touch screen 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. Added to this is the low noise level and 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 shift) and Christie's 1DLP projectors came out on top”, comments Patrick Müller. "Besides, with the laser lighting source there is no problem achieving the desired result, although they have passed 10.000 o 20.000 hours”.

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

The flexibility offered by projectors with a 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 output of the projectors in a relatively dark environment: “The results and resolution were extraordinary, especially in the case of the Großglockner digital elevation model, created in 4K resolution with a width of just 1,77 metros”.
