An information providing medium for providing a computer program for use in a three-dimensional virtual reality space display processing apparatus for decoding three-dimensional graphics data to display a three-dimensional virtual reality space image, said computer program comprising the steps of:
- storing said three-dimensional graphics data on a file basis on which a three-dimensional virtual reality space is described;
- and
- automatically generating three-dimensional graphics data described with an entry room in which a three-dimensional icon is arranged in a three-dimensional array, said three-dimensional icon being corresponding to said three-dimensional graphics data stored in said storage means on said file basis.
