Christie provides precise mappings at Global Shift

October 22, 2019

LINZ, Austria Global Shift at the Ars Electronica Center is using a wide selection of Christie® projection to examine the influence of technological progress on natural living environments. The exhibition employs models and projections to show how the world and our view of it have changed because of digital progress. Whether digital infrastructure, Earth observation via satellites, or data collected on us every day, it provides insight into the current conditions of our living environment.​

Working with Christie partner Ton & Bild Medientechnik GmbH, Ars Electronica Solutions selected one Christie 4K10-HS, two Christie 4K7-HS, five Christie Captiva DHD410S 1DLP® projectors, and three Christie LWU650-APS LCD laser projectors for the project.

Satellite imagery provided by various institutes and organizations was prepared in various elevation models for the precise mappings using Christie TWIST Pro to perform this precise terrain mapping (Großglockner and surroundings) in a small area with 4K resolution.

"We are currently working on the digital elevation model for Upper Austria, Salzburg and surroundings, as well as the digital elevation model of the Großglockner with the HS Series from Christie. In addition to this, a projector from the HS Series is being used for the installation 'ORBIT – A Journey around Earth in Real Time' by ​Séan Doran," comments Patrick Müller, technical director, Ars Electronica Solutions. "We connected the projectors using DP 1.2 fiber optic extenders, ensuring that they are fed the maximum resolution of 3840 x 2160 pixels at 60 Hz."

The installations are controlled using touchscreen interfaces to display and hide the various animated layers of the terrain models or even combine them. The Christie BoldColor Technology integrated in the HS Series proved particularly impressive and helped the team reach their final decision as to which projectors to use. Their low noise level and long service life also spoke in favour of the projectors. After all, they are in continuous operation six days a week.
