----------
In one flyover, we circle around the 800-metre-wide Victoria crater, swooping down past a virtual Opportunity rover and into the crater itself, then skim over the dunes on its floor and climb up the opposite crater wall. ---------- - New 3D 'flyovers' let viewers swoop down on Mars -------------------- - blue_scape / Nico -

The Beacon doesn't look as prominent as it does in Opportunity's images, yet the dunes on the floor are unrealistically sharp. I wonder where the elevation data comes from and whether the movie used vertical exaggeration.

It's from HiRISE stereo imaging - hopefully Randy Kirk will release a DEM so that I can do some HD res renderings of both sites
(oh - and I think it was rendered using Terragen, the clouds and lensflare seem to be a bit of a giveaway) Doug |

I'm quite sure there's no vertical exageration in the Oppy movie (unlike Spirit's). Indeed, they didn't need any! I think the dunes look odd near the end because they're viewed from a glancing angle, while the imagery was obtained from above.
I think they did a superb job with Victoria's flyover! |

I think the dunes look odd near the end because they're viewed from a glancing angle, while the imagery was obtained from above. The dunes just plain didn't work well with the DEM, at least, from the one that I saw (Likely the same one). In fact, I've been told the human eye plays the same trick from a distance, so I guess it isn't too bad. There was a quote at the HiRISE team meeting: "Victoria Crater is the Worst Place at Mars" (Followed in small print) "for Digital Elevation at Mars". It's just not an easy area to do it. |

Did anyone notice the little jig Opportunity does on the rim. She seems to move back and forth...
