Visitors seated on a custom-built 360-degree rotating platform can enjoy a multimedia show named “Hutian Fantasyland” inside the Taiji Cave in China’s Anhui province. “Hutian” is a Chinese word that is usually interpreted as a “dwelling for celestial beings.”


“The cave environment is complicated, and making measurements was extremely difficult,” says Xu Zhenfeng, general manager of Shanghai Hehao Technology, which implemented the project in collaboration with Summit Splendid Studio. “In order to provide designers and engineers with accurate design inputs, we deployed high-precision 3D holographic scanning equipment to digitally map and reconstruct the site.”


Choosing equipment that operates well inside the cave’s humid environment was another key criterion, Xu notes. The show runs on more than a dozen Christie DWU1075-GS 1DLP laser projectors, plus Christie’s real-time edit and playback controls.


Christie technology recently powered several other Chinese projects, including “The Great Lanzhou” nighttime extravaganza along the Yellow River in Gansu province; a large-scale outdoor light show on Nianhua Bay in Wuxi, Jiangsu province; and pathway projections on Sichuan province’s Guangwu Mountain.
