PROJECTS

Tsunami visualization & interface research

UkeeSIM is a prototype taskable virtual environment with a fully 3D representation of the town of Ucluelet BC, including topography, bathymetry, buildings and vegetation. Computational fluid dynamics simulations can be run in this environment. The objective of this interface is to enable planners and citizens to explore how different tsunami scenarios may play out in this community.


Virtual Ucluelet is an explorable, interactive virtual version of the town of Ucluelet BC, running on a 3D game engine. By contrast with UkeeSIM, this environment support individual and collaborative exploration of a virtual version of Ucluelet, before, during and after a tsunami event.. The interface is intentionally designed to support freeform user actions - as a way to introduce citizens to the symptoms of tsunamis in the context of their own community, and from a first-person perspective.
