A system and a method for rapidly and efficiently transferring the data required to construct virtual objects from a server to a user computer, by specifying the virtual objects as a plurality of controllers. Each controller may optionally be determined as a pseudorandom number generated from a particular seed, such that only the seeds need to be transmitted to the user computer as a serial number in order to display the virtual object. Alternatively, the virtual object may be specified as a part of an object hierarchy, in which only the parent object is fully specified. The child objects are then only described according to one or more differences from the parent object, such that only the controllers with different values are given for each child object. The system optionally features software tools operated at a remote site, for example by a remote server, provided for the user to be able to design a virtual object. The user interacts with these software tools through a client which is operated by a user computer. The user computer is connected to the remote server by a network, such as the Internet for example.
