Abstract
In one example arrangement, an immersive projection system includes an enclosure, and a number of projectors suspended outside and near the upper portion of the enclosure. The projectors project portions of a scene through openings in the enclosure and onto an inside surface of the enclosure. In some embodiments, light emanating from the projectors reflects from one or more mirrors before being cast onto the enclosure wall. The projectors and one or more mirrors may be mounted to a mounting frame that maintains the projectors and one or more mirrors in fixed spatial relationship, and the mounting frame may be mounted on a movable gantry for lifting the mounting frame to the upper portion of the enclosure. The enclosure may be a collapsible dome.
