Nicely done... what vertical resolution did you use - 8 or 16 bit? The
Olympus Mons flyaround shows some "terraced" terrain usually seen with
8-bit grayscale heightfields...

Meanwhile, there should be higher-quality data downloadable... if only
NASA servers would not be so chaotically structured!
I myself plan to do planetary flyovers with spherical "heightfields", i.
e. mesh2 reliefs wrapped around a sphere, like this:

Your nickname indicates that you're from Cologne - or at least the
bordering Ripuarian-speaking regions... am I right?
See you in Khyberspace!
