One of the goals for Ecosynth is to develop a highly interactive 3D viewer of our ground scans, where users can virtually walk through a forest and interact with the point cloud; select and identify individual trees, tag species, etc. 

This fellow named Stavros developed a WebGL/Javascript terrain flyover app. While at first glance it doesn't look super relevant, there are some interesting features that might be useful for us. For starters the user controls might be something we wish to mimic for our app. The way the terrain is loaded and memory management might also be useful, particularly if we start working with large point clouds. His blog details some of the inner-workings of the engine here.

Additionally his app has the ability to drape the Octree structure over the landscape (the orange boxes in the screenshot above). There are a lot of nifty little feature we may wish to incorporate from this app.
