A sculptural camera turns a game engine into cinema

The last time I had coffee with Kevn Peter He, he walked me through his elaborate setup and it dawned on me: The instrument is a camera. At LIVE SYSTEMS, an off-SIGGRAPH performance night at Spectra Studio in Los Angeles in late July, Kevin Peter He performed PASSAGE—piloting an unbroken take through a simulated forest, live in a game engine, with a sculptural camera controller built for the purpose. Dan Gorelick scored the run on cello and a custom-designed electronic instrument, and the framing in the announcement is key. Kevin Peter He called watching the visual and musical instruments interact in real time "a meaningful step for the work," and that word—instruments, plural—is doing the heavy lifting.

PASSAGE imagines an ecosystem as a living circuit board: metallic roots braided into living flora, with fans, lightning and fire cycling through growth, collapse and renewal. On the project page, the work sprawls across more forms than most game projects allow themselves—a live cinema performance, an installation where AI-governed deer diagnose faults in the forest's root systems, a prosthetic limb for an over-pruned ficus in a Financial District lobby, even a room fragrance that opens as forest and dries down to cold metal. And there is Passage.exe, an objective-less exploration game in which the player cannot alter the ecosystem at all—only navigate, frame, and observe it. Gameplay as an act of documentation.

This is territory I keep returning to. Indira Ardolic's live-coding sets turn game engines into instruments, and Jakob Kudsk Steensen talked with us about art, ecology and the game engine as a site for slow attention. What Kevin Peter He adds is the camera itself as the played object: virtual production's hidden labor of framing, calibration, and control, pushed onstage and given a score. The film does not exist until the hour is over—you watch it get made.
