This paper analyzes the properties of virtual objects in virtual reality and proposes amethod for description of virtual objects. This method will assist virtual world buildersto solve the problem of the dull performance of the virtual reality software, and tomake virtual objects more realistic in virtual world by way of defining the models andadding intelligent parameters. The Virtual Object Modeling Method (VOMM) was developed to describe the interaction among the virtual objects. Thus, the virtual environment will be more realisticin application packages.
