Korean multimedia integrators SoundKoreaENG and Metaspace staged a 3D projection mapping show for the Seoul Light DDP Autumn Festival that ran August 29 to September 8, 2024.
The show lit up the 222m façade of the Dongdaemun Design Plaza (DDP), designed as the world’s largest three-dimensional amorphous structure by British-Iraqi architect Zaha Hadid.
The DDP's curved exterior resembles a mushroom hovering above the ground and was a challenging canvas for 3D mapping.
The production team positioned 26 projectors, routing fourteen Barco UDX-4K40 and twelve Barco UDX-W32 units to a single Screenberry Atlas x8 media server using seven Datapath Fx4 multi-display controllers.
Screenberry also handled audio output for the show, with an additional media server as a back-up.
Content mapping and alignment on intricate shapes
By using a digital model of the building and pose estimation algorithms, Screenberry 3D Scene Editor adjusted the position, orientation, throw ratio and lens shift of the virtual projectors to match the physical ones.
This technique merged all projectors into an image and mapped the building with pixel-perfect precision, while reducing set-up time.
Sangdong Kim from SoundKoreaENG said: "DDP's façade is composed of thousands of unique tiles. To transform it into a projection mapping surface, the calibration grid must align perfectly with each tile. Screenberry's calibration tool set allowed us to achieve this with remarkable precision."
The projections referenced the works of globally acclaimed Korean artist Kim Whanki, whose abstract paintings are known for their diverse hues, patterns and lines. Media art label ‘Verseday’ also created a projection show celebrating the 10th anniversary of the DDP by exploring the connection between past, present, and future through digital art.
