Abstract:
|
We describe a hybrid client-server technique for
remote adaptive streaming and rendering of large terrains in
resource-limited mobile devices. The technique has been designed
to achieve an interactive rendering performance on a mobile
device connected to a low-bandwidth wireless network. The
rendering workload is split between the client and the server.
The terrain area close to the viewer is rendered in real-time by
the client. The terrain located far from the viewer is portrayed
as view-dependent impostors, rendered by the server on demand.
A prototype has been built and an exhaustive set of experiments
covering several platforms, wireless networks and a wide range
of viewer velocities has been conducted. Results show that the
approach is feasible, effective and robust. |
