VVVV patch visualizing NMEA GPS data. The longitude and latitude coordinates are processed to mercator projection X/Y coordinates. That coordinates plus the GPS height are interpolated using the B-Spline node to add some vertices and smoothing the curves. The width of the path is relative to the GPS speed. The camera movement is in realtime and generated by the LookAt node.
This demo shows the GPS data of a MikroKopter flight - big thanks to CaScAdE for taking my GPS Logger on a flight!
