Abstract
This paper introduces a model to represent the evolution of VR objects over time. Based on this model a new classification of
virtual reality objects is proposed and the semantics associated with each class of object are described. This paper also
presents a rationale for modifying object semantics under manipulations by an observer of the object behavior. The
manipulation of the spatio-temporal configurations of VR objects and their behaviors allows observers to create their own
visualization of the environment, gaining insight and discovering relationships among dynamic phenomena.
