Abstract

Distributed virtual environments offer an efficient way of creating complex 3D worlds. However, navigation within these virtual environments can be significantly hampered by the lack of visibility between parts of the world which are on different machines. This paper describes the use of portals to connect the distributed virtual environments in a way that the interconnected virtual environment will be visible from different machines. A psychophysical experiment is presented which investigates user navigation inside a globally inconsistent virtual environments by using portals compared to traditional VRML Anchor based hyperlinks.
