Korean multimedia integrators SoundKoreaEng and Metaspace appointed Screenberry to power a 3D mapping show for the Seoul Light DDP 2024 Autumn Festival.
The festival took place in downtown Seoul for 11 days from August 29th to September 8th, 2024.
The highlight of the event was a projection mapping show on the Dongdaemun Design Plaza (DDP). The DDP's futuristic exterior, with its fluid, curved forms, resembles a colossal mushroom hovering above the ground. This unique architecture offers an exceptional but challenging canvas for 3D mapping.
To illuminate the expansive 222-meter facade of the DDP, the production team employed 26 projectors (14 x Barco UDX-4K40 and 12 x Barco UDX-W32) placed in seven containers that were positioned at varying heights in front of the building. Orchestrating this vast array of projectors was a Screenberry Atlas x8 media server. To route the 26 outputs from the single media server, the team utilised seven Datapath Fx4 multi-display controllers. Screenberry also handled the audio output for the show.
Moreover, Screenberry's advanced 3D Scene editor was being used for the project, which offers tools for precise content mapping and alignment on intricate 3D shapes, such as those at the DDP. By utilising a detailed digital model of the building and employing pose estimation algorithms, Screenberry finely adjusted the position, orientation, throw ratio, and lens shift of the virtual projectors to perfectly match the physical ones. This technique allowed for merging all projectors into a seamless image and mapping the building with pixel-perfect precision while significantly reducing setup time.
