SYSTEM AND METHOD FOR DISPLAYING TWO-DIMENSIONAL AND THREE-DIMENSIONAL GRAPHICAL MODELS OF A BUILDING

摘要

A system and method for aiding spatial orientation of displayed graphical models of structures. A monitor displays the graphical model and an input commands a processor to selectively display the model as a two dimensional model or a three dimensional model. The processor displays selected features such as specific areas of the structure, fire hydrants, elevators, smoke detectors, fire detectors, stairways, and individuals within the structure. The processor selectively changes between a two dimensional model to a three dimensional model over a noticeable period of time. A selected floor is shown as decreased transparency and the remaining floors with increased transparency or it is tinted. A wire frame can highlight the one floor or the entire structure. Exterior features of the structure may be shown. A circular scroll bar controls rotation of the three dimensional structure while maintaining the user's orientation in virtual space.
