Virtual London in Second Life – Rezzing a City of 3.3 Million Buildings


As part of our GeoVue project at CASA we have the first working example of porting areas of Virtual London into Second Life.

Created around a simple North/South /East/West interface the city has been split up into sections with data loaded as and when required – in theory the whole of London could be loaded in over time.

Second Life has many restrictions on importing objects, our method ports a KML from an extruded building footprint with height attributed via LiDAR data.

The work so far is proof of concept rather than a polished model, as the movie below demonstrates:

Loading of sections is currently slow, this being worked upon, the next phase is to read in real-time GPS data of a pedestrian and to get the city to build around him/her while they walk…

Thanks go to Joel for writing the code.
