I've modified my Mars Explorer terrain engine to use the new HiRISE data. This video shows me flying around the Gullies DEM. It's running at about 30 fps.

Thanks for the comments.
@Nirgal. I don't know of a c/c+ library for MPEG encoding I'm afraid. I just output bmps and convert to mpeg using bbmpeg. Here's another animation, this time of Gale crater. I have increased the texture resolution from 1m to 0.5m since the last animation. I'm still not using the full resolution of 0.25m. Until I get some new hardware that's not going to be possible. http://www.youtube.com/watch?v=Cq0Z3cKJaGQ |

Phantastic ! I like how the slow motion, the subtle sky coloring and the long distance view towards the horizon all contribute to the realism (I even like the sun flare effects and the slight vertical height exaggeration when they are so subtle and realistic ). How many polygons do you render per frame ? ... must be well into the millions especially towards the far horizon view ... QUOTE @Nirgal. I don't know of a c/c+ library for MPEG encoding I'm afraid.

But maybe if time permits, I'll be give it a try too |

What makes you think there is some? I have checked my code and cannot see any errors re. height scaling. Sometimes it reaches about 2.7 million polys per frame. The framerate mostly stays above 60 now since I made some optimisations. |
