Activities
Model
As part of the COVEN project, we are building a travel rehearsel
scenario involving a journey from London Heathrow Airport to
University College London. The aims of this are to prove the utility
of collabortive virtual environments, explore the generation and
support of very large models and to explore scalable rendering
systems. You may download cut-down versions of this model in VRML1.0 and DIVE3.2 formats here
