Distributed Virtual Environment (DVE) topology management and
message propagation schemes have been proposed for many years. Evaluating
DVE message propagation schemes requires a variety of assumptions whose
verity significantly affects results, such as details about avatar movement
characteristics. We implemented two schemes for waypoint and hotspot
detection, and examined their applicability for characterising avatar movement.
We confirmed that waypoint detection does not yield good results for
characterising human avatar movement, and gained new insight into why by
rendering avatar movement as point clouds. We implemented an existing
hotspot detection model, and proposed an enhancement to help overcome one
limitation of cell-based hotspot detection. We were able to immediately apply
this hotspot detection technique to help analyse group movement. We
discovered that although a third of movement time in the battlegrounds is spent in inter-node journeys, less than a quarter of these journeys are made in groups.
