openstreetmap osm roads data to html5 arrays 3D car sim

json_osm_chung is an open source realtime online converting openstreetmap servers osm real roads data to html5 arrays to use with a game or in this example to draw on a graphical canvas or 3D webgl. Use the arrow keys to move or select one of the presets locations. recreate any real roads + buildings places in the world . mixed with google static maps satellite ground images , water terrain detection , srtm terrain heightmaps, trees , lamps,  and webglcarsimheight  a small free 3D driving car simulation game. Can  run on a small netbook. works better with firefox .

how does it work ? In osm, you have ways and nodes. A way is a line of nodes, nodes composed by latitude and longitude . A way can discribe a road, a building contour, a forest contour, an airport ...  All this is available online in realtime via json javascript api .(nothing to install)
