Abstract: A method for transforming world coordinates into device coordinates comprises the steps of inputting a set of world coordinates to be displayed, scaling the world coordinates into view coordinates bounded by a display volume, finding a control memory location of a light beam deflector corresponding to a Y-axis position for each of the view coordinates, calculating X-axis and Z-axis device coordinates from the view coordinates for deflecting a light beam to a selected point within the display volume corresponding to each of the view coordinates, and loading the device coordinates into the control memory locations corresponding to the Y-axis position for each of the view coordinates to cause the light beam to be deflected to each selected point.
