WGS84 Projections

For our WebGL Augmented Reality App, we needed to preprocess latitude and longitude values into localised coordinates. Lat/lng values are great, but they are not very useful if you need to represent them inside a 3D space. It is far better to use [x,y,z] coordinates which are stored as floats natively and can be used directly without projecting them into another coordinate space. Of course, you are better off using lat,lng values if you are looking at very large distances on a globe.
