Screenberry powers 3D mapping on Seoul’s DDP
The Seoul Light DDP 2024 Autumn Festival featured a 3D mapping show on the Dongdaemun Design Plaza (DDP), powered by a Screenberry Atlas x8. The solution was deployed by Korean multimedia integrators SoundKoreaENG and METASPACE and illuminated the Zaha Hadid-designed structure for the 11 days of the festival.
Renowned as the “world's largest three-dimensional amorphous structure”, the DDP's futuristic exterior, with its fluid, curved forms, resembles a colossal mushroom hovering above the ground, offering a challenging canvas for 3D mapping.
To illuminate the expansive 222-metre-long facade of the DDP, the production team employed 26 projectors, 14 Barco UDX-4K40s and 12 Barco UDX-W32s, placed in seven containers that were positioned at varying heights in front of the building. The Screenberry Atlas was used to orchestrate the vast array of projectors. To route the 26 outputs from the single media server, the team utilised seven Datapath Fx4 multidisplay controllers. Audio output was handled by Screenberry and an additional media server served as a hot backup.
Screenberry’s 3D Scene editor, which offers tools for content mapping and alignment on intricate 3D shapes, was leveraged for the project. By utilising a digital mode of the building and employing pose estimation algorithms, Screenberry adjusted the position, orientation, throw ratio and lens shift of the virtual projectors to match the physical ones. This technique allowed for merging all projectors into an image and mapping the building with precision while reducing setup time.
“DDP's façade is composed of thousands of unique tiles,” explained Sangdong Kim of SoundKoreaENG. “To transform it into a projection mapping surface, the calibration grid must align perfectly with each tile. Screenberry's calibration toolset allowed us to achieve this with remarkable precision.”
The abstract paintings of Korean artist Kim Whanki, known for their exploration of diverse hues, patterns, lines and spaces, were featured in the projection show. Additionally, the media art label ‘Verseday’ created a projection show celebrating the 10th anniversary of the DDP by exploring the connection between the past, present and future through light and digital art.
