A database of objects is distributed between a server computer and
multiple client computers as an object oriented virtual world environment
(VWE) with multimedia presentation features. A primary database is
maintained on the server and includes at least one entry for each object
disposed within the VWE. In one implementation a presentation virtual
world environment has a multi-user virtual presentation room object
(ShowRoom) in which presentation or information element objects
(ShowItems) are presented from a server to multiple viewers at multiple
client computers. The presentation room object and presentation element
objects are global objects in that they are provided from server to
client computers as part of a presentation VWE. The presentation element
objects provide a model representing a presentation in the presentation
VWE. Interface objects at the client computers provide a view of the
presentation, with user interface and control elements, which view is
separate from the model provided by the presentation element objects.
