1. A three-dimensional display device comprising:

  • display means for displaying on a two-dimensional screen three-dimensional objects, a vector cursor virtually located in a three-dimensional space and moving in said space, and a pointer extending from the vector cursor in a direction of movement of the vector cursor for selectively identifying objects intercepted thereby in the three-dimensional space, in response to a display signal;

    input means for inputting a parameter for changing the direction of the vector cursor and a pointing signal for controlling said pointer to identify a three-dimensional object displayed by said display means; and

    control means connected between said display means and said input means for generating the display signal to display the three-dimensional objects, the vector cursor and the pointer, and including means for recognizing a three-dimensional object pointed to by said pointer in response to the pointing signal.
