This clip shows a GPS unit displaying the directions to a particular destination. Once the animated route, drawn in red, reaches the destination, the camera plunges into the screen of the GPS and the cityscape shown on the GPS screen transforms from an orthographic top view to a 3D perspective view.
The elements shown on the GPS screen are rendered in a separate pass, then composited into place within the rendered footage of the GPS unit. The footage of the GPS unit featured a chromakey green on the GPS screen which was used to derive an alpha mask that included the bezel with curved corners. The cityscape footage was motion-tracked to match the zoom into the GPS screen.
