Abstract:
A method of sharing a three-dimensional virtual reality space, comprising the steps of:connecting a plurality of client terminals for displaying a three dimensional virtual reality space including an update object formed of at least two sub objects located in a predefined relationship with respect to each other and each having a state independently subject to change by a shared server terminal for controlling the state of the update object on each of the plurality of client terminals via a communication network; registering in each of the plurality of client terminals a change sequence table for defining a relationship between a sequence of changing the state of each of the plurality of sub objects according to a change to the state of the update object and a message for specifying a type of the change sequence; simultaneously notifying each of the plurality of client terminals of the message corresponding to the updated content of the state of the update object from the shared server terminal when the state of the update object controlled by the shared server terminal is updated; and synchronously changing on each of the plurality of client terminals the state of each of the plurality of sub objects based on the change sequence specified by the message to reflect the change in the displayed three-dimensional virtual reality space.
