A new method for image-based rendering (IBR): rendering using plane slit image field is discussed in this paper. Slit image field is a set of slit images that can represent and generate all scenes in a given region. A concept of analogical slit image is presented. By using it, a method to reconstruct the slit image field as well as work-through scenes from limited samplings is presented. A slit image segment mapping technology to simplify the reconstruct process and reduce data is presented too.
