Abstract
In order to enable plural users to share a virtual environment which includes not only simple shape data, but also data of an object having a highly complicated shape, a terminal equipment displays the virtual environment. The virtual environment is obtained when viewed by a user of the terminal equipment on the basis of tree-structure data composing the shape data, light space data and the like as components. The tree-structure data is changed when the shape data or the light space data is subjected to a process such as movement or the like. The changed information of the tree-structure data is transmitted to a server, and the server changes data in a data memory device based on the received changed information. The changed information is transmitted to another terminal equipment which displays the virtual environment obtained when viewed by the user of the another terminal equipment on the basis of the received changed information.
