Visual developer Bruno Imbrizi‘s 3D map lets users track trains on the London Underground in almost real-time. They can toggle between the different lines and can rotate, pan and zoom around them.
Imbrizi used train times and the latitude, longitude and depth of the stations to create the visualization, using a simple tool with Adobe AIR to combine these from different files. He writes:
One of the biggest challenges was to make the trains follow the spline and sometimes change splines depending on the train’s destination. I feel that my algorithm could be more solid here, but it is working well. The last touches were to add the labels for each station and add some ambient sound recorded at the tube.
