Add 3D Buildings to Scene

[Glavin001]

Initially only use the vertices given from the Open Street Maps data and then a fixed height for all building walls. Worry about realistic / dynamic buildings later, once more data is accumulated.

• [ ] Roofs
• [ ] Lighting
• [ ] Shadows

I recommend taking a look at: http://stackoverflow.com/questions/15067455/how-to-render-a-building-using-webgl-three-js-extrusion-method

[Glavin001]

Take a look at the following article discussion lighting and surface materials: http://japhr.blogspot.ca/2012/07/lights-and-materials-in-threejs.html

And for casting shadows: http://learningthreejs.com/blog/2012/01/20/casting-shadows/

Another amazing example of buildings in 3D: http://www.jabtunes.com/labs/boidsnbuildings/ It's very cool.

That IS verry cool.

Building extrusion causes the following phenomenon. Need to fix.

Yes, those grey blobs in the sky are Halifax's buildings... a little bit out of place ;).

[Glavin001]

Extrusion of buildings no longer makes sense: you want players to be able to enter, therefore a wall-based building object makes more sense than this extruded "solid" building. Not to mention, it's easier as it was working before and now the extrusion is up in the air ;)!
