Many image-based modeling and rendering techniques involve photographing a scene from an array of different viewpoints. Usually, this is achieved by moving the camera or the subject to successive positions, or by photographing the scene with an array of cameras. In this work, we present a system of mirrors to simulate the appearance of camera movement around a scene while the physical camera remains stationary. The system thus is amenable to capturing dynamic events avoiding the need to construct and calibrate an array of cameras. We demonstrate the system with a high speed video of a dynamic scene. We show smooth camera motion rotating 360 degrees around the scene. We discuss the optical performance of our system and compare with alternate setups.
