Tracing the Sky 伫林染天
Tracing the Sky is an immersive mixed-reality installation presented in Manchester, United Kingdom, situated within a hidden underground chamber beneath a Victorian arcade. The artist began by conducting high-resolution 3D scans of this enclosed architectural relic—its bricks, vaults, domes, and cracks were translated into digital models. Through this process, the historical space was reimagined as a virtual architecture composed of data; the material structure of reality entered a state of temporal suspension within technology. The scanned data were then imported into a simulation system and reconstructed as a field of particles—a deep blue "sleeping space," a digital stratum suspended between memory and futurity.
Dreamlike projections float softly across the vaulted ceilings and brickwork, while a virtual sky gradually unfolds beneath the earth. Air and architecture, sky and ground, become reciprocal presences within the same field: the solid outlines of the building dissolve into light, gain form through the resistance of the structure. The work allows the virtual and the real, the tangible and the intangible, the natural and the constructed to coexist within a single breath, generating a constant oscillation between stability and flux.
The installation utilizes projection mapping and augmented reality (AR) technologies, allowing viewers to interact in real-time with the simulated atmosphere through their mobile devices. As they move, clouds drift and light changes in response to their gestures, activating the space through cycles of perception and feedback. Sounds generated by these interactions reverberate through the vaulted architecture, forming an enveloping sound field. Visitors walk within echoes, as if moving inside a building that breathes.
By combining art and technology, Tracing the Sky creates a poetic exploration of humans' relationship with their environment. The artist invites people to perceive the space not as a passive site of display, but as a living field for thought and sensation—a place to listen, to reflect, and to feel the subtle bond that connects body to nature, to the atmosphere, and to the infinite expanse of the sky.
