Hospital with one entrance and two exits is a virtual reality piece created from pointcloud data generated by a laser scan acquired at a hospital in Istanbul. The piece responds in realtime to viewer attention; interaction shapes the the virtual space itself. Moving through an operation room corridor–with stretchers, surgical equipment, and the buzzing sound of fluorescent lights–the viewer sees the hospital through machinic vision, through point clouds. The hospital is a place where tactile and intimate knowledge of the human body is enhanced by advanced medical imaging technologies to diagnose and treat the human body. In this piece, the objects and buildings are in turn subjected to a similar examination. The piece is a meditation on machinic vision: laser scans of the hospital itself are interpolated with CT scans of human bodies. At certain moments, the viewer grapples with a change in perception such as the sudden ability to peer across vast spaces with subtle movements which are lost quickly once mastered. The point cloud data transforms the space and the observer in the space. The way the building appears, disappears, is transparent and at moments quite legible forms a fluctuating consciousness, a perception that is neither of the animate or the inanimate.
