I wanted to add some additional content to the project, and from a geographic-perspective a set of airline flight paths was a convenient choice, as shown below in Figure 1. Note that the routes are plotted as minor arcs of great circles rather than actual flight-paths, and that the height has been exaggerated for clarity.

Figure 1. Flight-path1 data plotted over earth-lights2, filtered by airline as British Airways. Shown in both color and red-cyan anaglyph.

One of the implications of this was that I had to implement the a tile-based earth-renderer for sufficient levels of detail. Fortunately I already had some code for this from another project which required minimal modification.
