With that high-definition 3D scanned data map, the team managed to install the 14 DWU1075-GS projectors in the best points of the main chamber, without damaging the walls or rock formations of the cave. “The next challenge was to execute the color control and calibration process, “a very complex task given the irregularity of the surfaces”, adds Xu. “Repeating the projections over and over again, “The sound effects and environmental tests ended up achieving a perfect feeling of immersion.”.
