A number of stereoscopic cylindrical displays have been developed over the years, the most recent being the CAVE2. Some of these, unlike the traditional CAVE environments, provide a seamless 360 stereoscopic image without corners [AVIE] and thus can support a heightened sense of immersion. Most immersive displays that consist of discrete walls rely on head tracking and are thus only intended to be a single person experience. For cylindrical displays a method is well known by which stereoscopic panoramas can be presented without the need for head tracking, these stereoscopic pairs are generally referred to as omni-directional [Ishiguro et al, 1992][Bourke 2006]. This allows large cylindrical displays to be constructed that support multiple person audiences with each person potentially looking in a different direction.
A digital alternative for the film based rotating slit camera has been developed, figure 1 (right). It is based upon a motorized rotating head and employs either a digital video camera (Red Scarlet) or a SLR camera (Canon 5D MKIII). Only a single camera is required, two vertical stripes are extracted from each frame, these are each arranged consecutively to form the stereoscopic panoramic pairs. This technique has a significant
