Beyond Flat Panning and Zooming: Dolly-Enhanced SQTVR

This paper describes a novel solution to problems associated with interactive display of immersive stereographic imagery via Apple’s QuickTime Virtual Reality (QTVR) technology. A unique multinode implementation providing Stereographic QTVR (termed here SQTVR) enables the display of pairs of images exhibiting binocular parallax, and the stereoscopic depth percept that results is enhanced by motion parallax inherent in a subtle translation of the viewpoint through the displayed 3D scene. Stereoscopic depth is maintained as a user pans freely through a complete ¢¤£¦¥¨§ horizontal panorama, while the system imposes a slight dollying in and out of the scene as a user’s view rotates left or right. In addition, SQTVR solves two problems that can be observed when users of conventional QTVR technology change viewing positions, and these are problems that generally interfere with a user’s sense of immersion and telepresence. First, objects that should be revealed (“disoccludedâ€...
