1. A 3D (three-dimensional) object graphics display device for displaying a 2D (two-dimensional) graphics image by performing image processing on prestored 3D object image data, said 3D objects graphics display device comprising:

  • a manipulator for outputting position information, said manipulator having at least two degrees of freedom and allowing free rotation; and

    calculation processing means for generating, when said manipulator indicates a reference position, a 2D image of a 3D object seen from a particular viewpoint, and for generating, when said manipulator points to a position apart from said reference position by a displacement amount, a 2D image of said 3D object seen from a viewpoint shifted by an amount corresponding to said displacement amount, said generating being carried out on the basis of 3D shape data and texture data of said 3D object, which are prestored in a storage as said 3D object image data, said calculation processing means iterating said image generating at a minimum display interval of every 1/60 of a second and completing a 2D display within 1/60 of a second from a beginning of said image generating.
