Modelling of a virtual environment with a reusable method

Abstract

One of the important issues of the virtual reality researches is the design and management of the scenario database. Traditionally,the historical data of a virtual world are imported manually and laboriously into the scenario database, Based on the standard proposed by American DOD(Department of Defense),the virtual world can be expressed by the Federation Object Models(FOM) and Simulation Object Models(SOM) from the High Level Architecture(HLA).For the future HLA-compliant simulation, the scenario database format should base on the standard of Object Model Template(OMT).This papaer proposed an easy-use,semi-automatic, and reusable framework for managing the historical scenario data. The major components of the framework are a Scenario Designer and Data Importer.In this way, the data in the scenario database can be easily reused to restore an original virtual world or generate a new virtual world. An example is also presented to verify this framework.
