A virtual reality environment creation, modification and delivery system stores information representing the virtual reality environment in a database where portions of it may be created, modified or delivered without affecting other portions. The database may be accessed, for example, over a network such as a wide area network, to allow database records to be individually updated without affecting other records in the database. In this manner, it is not necessary to read and store an entire virtual reality environment file in order to make changes to it. In addition, characteristics of target machines dictate what version the database reads out, thus to provide a version compatible with the target machine.
