Panoramas General Considerations | Cylindrical | Spherical | Cubic Rectilinear | Multimedia Panos Panoramas (panos) display all or part of the surrounding environment observed from a particular viewpoint. Many types of panos are interactive and allow rotation, tilt and zooming of the surrounding scene. They are synthesized from digital photographic images. When building a pano, the content of one or more photographs is mathematically projected outward from the viewing position onto an imaginary 'bubble' that encloses the viewer's environment. This 'bubble' can take one of several geometric forms including cylinders, spheres and cubes. Rectilinear panos resemble traditional photographs. All or part of a panoramic ‘Bubble’ can be 'flattened out' to create a rectilinear pano. This is similar to making a flat map of the approximately spherical earth. Another example is the cutting of a cylinder so it can be unrolled on a table. Rectilinear panos are excellent for building very high resolution images and images with a very wide field of view. Panos are a cost effective method of building an interactive environment. This environment may also serve as visual framework for linking other types of digital media, providing an integrated multimedia experience. |
