The system welds adaptive films whose every viewing is unique. Viewer attention reconfigures spatial layout and camera logic on the fly, collapsing editing, filming, and watching into one continuous act. Synthetic duration unfolds as a volumetric artefact rather than fixed narrative—time rendered not as sequence but as navigable terrain where human inhabitation and machine intelligence collaborate to produce emergent spatial experiences. The work interrogates how spatial AI models integrate with robotic fabrication and responsive materials to construct architectures that register viewer agency as their primary structural logic. Each gaze, trajectory, and temporal rhythm becomes encoded into the film's material scaffold, positioning perception itself as the generative medium through which architectural form and cinematic duration simultaneously crystallize.
