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.

I hope to make a download of the software available in the next week or two.

Breathtaking!!!! Thank you!!!
For those that don't know - Adrian and I go back 10 years (we attended the opening of the National Space Centre back in 2000!) - and he made some stunning fly-through software for MOLA data back then. (I made a little Mars-Plane to go in it for fun)
And now he's BACK... with THAT.
Nice work
I propose a competition between Doug and Pete and Adrian. Here's how it will work. You all start making Martian DEMs as detailed and as long in duration as possible. Keep posting them here and we will all be the judges as to quality and quantity. The duration of the contest is a secret, so get started and we'll let you know when the competition has ended.
I'll second that!
Good to hear from you Doug. I took a long break from this kind of thing but the Hirise data was too good to miss and the LOLA data isnt too far away now either. Looks like I have busy time ahead
Congratulations on your animations Doug, great stuff!
Here's another animation, this one is of the Mojave crater.

Superlatives have gone by the wayside - all I can say is that you are getting to a level where this stuff is starting to look like it was taken by a real HD camera flying around Mars. Stu is going to love the Lens Flares in this one too.
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.

I agree- this is perhaps the most realistic animation I've seen yet- congratulations! I like that we're moving slowly enough to really take in the scenery.

Mars3D, that is tremendous work. Can you tell us at approximately what ground speed and altitude the camera is flying across the landscape? I know that it varies; I'm just curious to know what sort of aircraft I should imagine myself flying inside
Think local news chopper on a car chase
And I can see what Nirgal means - but that particular Gusev DEM is just awesome - it really is that lumpy!
Wow - no vertical exaggeration. It looks like rough terrain even for (or perhaps especially for) a three billion dollar nuclear powered rover. Could one of these images be modified to indicate a ground track for this flight, especially with respect to the anticipated Curiosity landing ellipse? Maybe there are even better context photos available - I just recalled seeing this one on the planetary society blog.

It's a wonderful flying sensation. I have tried the interactive flight simulator included in Google Mars, but this has much more detail. Just for fun, how about adding a sound track with some engine hum and the whistle of a very attenuated Martian wind?
One of the main selling points for MSL has always been that it should be able to land in more exciting areas (topographically speaking) than an airbag-equipped lander. (MSL used to stand for "Mars Smart Lander," but the meaning of the acronym was changed partway through development.) But you're right that some of this topography is too extreme for the landing ellipse. The other thing that MSL is supposed to be able to do is to land in a less exciting area and drive a very long distance to a more exciting area. http://www.planetary.org/blog/article/00001967/ on this -- Gale is a so called "Go-To" proposed landing site for MSL, where you arrive at the interesting stuff after a long drive.
(It's funny how many of my Google searches on topics lead me either to posts I've forgotten about on my own blog, or to past discussions I've forgotten about on UMSF!)
That dem area is reachable by Curiosity if it goes to Gale - but isn't inside the landing ellipse
In my earlier post, I did not really mean to focus so much on whether Gale was the best target for MSL/Curiosity or not. I have a lot of confidence that that decision will be made by people who are very good at balancing the risks against the rewards, and I also recognize that there will still be a lot of risk no matter what site is chosen.
What inspired me to write the post was the more general problem regarding the forest and the trees. Viewing the Pathfinder clip, it was easy to stay oriented because I was on familiar terrain with a small number of clearly recognizable landmarks. By contrast, the Gale clip took me down to a level of detail at which I was completely lost. Despite the wild, fascinating terrain and the giddy sense of flight, I couldn't relate what I was seeing to any map or 2D representation of the larger context. I wasn't even sure I could identify the consistent circularity of a crater wall. Even flying on airplanes here on Earth I have noticed that when the sun is high enough in the sky not to provide a reliable guide, it is difficult to maintain my sense of direction by simply counting the degrees in a turn. Maybe pilots have the experience to do this easily, but in my case, I'd really like to see the ground track from a higher altitude, so I could say to myself, "Oh, that's what that feature looks like from up close!"
Great stuff, Mars3D! We really get the impression that we're seeing the real thing!
DEM is 1m
Texture is 0.37m
It takes two elements to do these things - the elevation model, and the texture map you put on it!
I've upgdraded my RAM and tweaked the software and now I'm able to use the full HiRISE texture resolution (~25cm). Here's my first animation at the full resolution, this one shows Candor Chasma.

Stunning!!
Seriously, no vertical exaggeration? Wow... that's Mars' Monument Valley right there...
Simply amazing ! your best one yet ...
This movie is simply fantastic. If I didn't know you were working with DEMs, I would swear you were actually going to Mars in your own spaceship and taking your movies in situ.
Could you post a vertical view of the area showing the camera path?
Come on guys, stop that...this is too much.
Excellent! Was Candor's topography the main reason MSL got cold feet for this site, or are the remaining 4 sites much more promising for mission objectives?
Thanks a lot for the path! That's exactly what I was hoping for.
An idea just jumped into my mind. What if you added in a corner of your flyovers a vertical view of the area showing the path travelled and a moving dot indicating the camera location? A bit like what we see in computer games.
This is just a suggestion. It may not be easily feasible, and I can't even imagine the work needed already to create your flyovers, so don't think that I want to lay a burden on you, especially since I am a complete ignorant on the subject.
I have only now seen this last animation, after checking the latest entry on Emily's blog (http://www.planetary.org/blog/article/00002382/) and I truly think that such title is 100% right! It's an incredible experience.
(Doug, we should include additional emoticons to the editor; I was looking for one meaning "jaw on the floor" but couldn't find it)
Heres some new animations:
Olympus Mons Basal Scarp

Eberswalde crater moutain

These two animations were produced from the data here http://hirise.lpl.arizona.edu/dtm/dtm.php?ID=PSP_008272_1560. I am probably outside the MSL landing elipse with those animations but I am just picking the interesting scenery
I can now produce youtube animations in analygraph 3d using youtubes new 3d feature. This is just a test video of candor chasma to see if it works. You'll need the coloured glasses to see the 3d effect.

Incredible, you've stepped things up from the previous animations quite significantly. I love the FOV\context map and the altitude\speed indicators, they really help put everything in context. I've always wanted to wander around the Olympus Mons Basal Scarp but I never thought it would be as dramatic as this.
Pure gold.
Jeez, what else is there to say? These are spellbinding to watch. Thanks!!!
Amazing earlier animation of Candor Chasma - looks like being there, somewhat like parts of Utah. I looked on Google Mars to try and get some context for where this is:
