Distributed virtual reality, thanks to newly proposed paradigms, offers interesting perspectives to virtual world modelling. Our main interests are in applications which allow users to edit and deform existing shapes. This paper presents a concurrent virtual world modelling application based on those ideas. Herein is shown how concrete manipulations of tools (such as a hammer) are transformed into free form deformations of existing shapes. We also present a first implementation based on VIPER (Virtuality Programming EnviRonment) a generic distributed virtual reality development platform.
