Abstract
The new technology of virtual environments provide to a visitor of a virtual world a high degree of immersion. On the other hand, the interaction techniques available in these virtual worlds are still rudimentary. Frequently, the visitor is enabled to grab 3D objects by gesturing, but unable to touch a face, edge or a vertex, neither edit its shape interactively.
In this paper we present the reasons that let us believe that boundary representation data structures should be integrated in virtual environments. They can be used not only to provide a fast rendering, but mainly to take advantage of the explicit geometrical and topological data of 3D models. This data enabled us to improve the interaction component of a virtual environment prototype by letting visitors to locally edit in real time the shape of virtual objects and, in this way, augmenting the visitor participation in a virtual world.
