  • an autoscopic display device;

    a microprocessor for producing graphics instructions representing a current view of an object based on viewer position;

    a graphics engine, connected to the microprocessor, for converting the graphics instructions into data capable of driving the display device;

    a buffer, connected to the graphics engine and the display device, for storing the data;

    means for determining the position of a viewer relative to the display device of a type wherein the viewer carries no required apparatus to enable the determining of viewer position;

    means, connected to the means for determining viewer position, for determining the display position of the object based on the determined position of a viewer;

    means, connected to the means for determining display position and to the buffer, for determining read-out order of the data such that the data may be used to generate a display of that part of the object, in the proper position, viewable from the viewer'"'"'s position; and

    means, connected to the buffer, for controlling reading out of the data from the buffer in the order determined by the means for determining read-out order, so as to drive the display device to display only that part of the object, in the proper position, viewable from the viewer'"'"'s position.
