STEREOGRAPHIC DISPLAY DEVICE

PURPOSE:To display a three-dimensional pointer capable of being controlled electrically in a stereographic display device to display the three-dimensional point as a cursor which points out the desired position of a stereographically displayed target material. CONSTITUTION:A dot image is reproduced at an arbitrary position on stereographic display space designated by a position designation means 1 by a dot image reproducing means 2. For example, when the display position P (x, y, z) of the dot image for a phase distribution display plane 36 is designated, the phase distribution PHI of the dot image in accordance with designated distance (z) from the phase distribution display plane 36 is read out, and the phase distribution of a prescribed area including the origin O of a readout phase distribution display plane 38 is segmented as the phase distribution of the dot image in a state where the position H (x, y) of the dot image P on the phase distribution plane 36 is fitted in the origin of the readout phase distribution plane 38.
