Abstract

A method is disclosed for operating a processor-controlled machine to produce a composite view of an original, or first, image by combining the functions of multiple viewing operations and using the model data structure from which the first image was produced (called the "FIMDS".) A first viewing operation region (1VOR) in a first viewing position in the display area of the display device has displayed in the 1VOR a second image produced according to a first viewing operation (VO1), associated with the 1VOR, that maps the FIMDS to image definition data defining the second image. Request signal data is received from a signal source to present a second viewing operation region (2VOR) in the display area coextensive with at least a portion of the 1VOR, forming a composite viewing operation region in the overlapping region. The 2VOR has a second viewing operation (VO2) associated with it for mapping an input model data structure, typically but not necessarily the FIMDS, to image definition data defining a second image for display in the 2VOR (2VOR-SI), providing an alternate view of the FIMDS that is different from that provided by the VO1 associated with the 1VOR. In response to the request signal data, a composite viewing operation, composed from the functions of the VO1 and the VO2, maps the FIMDS to image definition data defining a composite image for display in the composite viewing operation region substantially at the same time as the first image is being displayed in the display area. This gives the perception to the machine user of applying composed viewing operations to information presented in the original image.
