Abstract
With employment of a pointing device equipped with at least one switch, and connected to a computer, both of a drawing position of a figure to be drawn on a display plane, and a size of this figure are designated. Another designation is made of a height of a predetermined region within the figure to be drawn, measured from edge portions of this figure to be drawn, along the vertical direction with respect to this display plane by employing the above-described pointing device. A further designation is made of a direction of light illuminated to the figure to be drawn by using the above-mentioned pointing device. Based upon the designated height and light direction, brightness of each of regions subdivided from this figure to be drawn is calculated, and each of the subdivided regions is displayed at the calculated brightness, so that this figure is three-dimensionally displayed on the display plane.
