Thought I'd start a new thread for stuff done with the HRSC DEM's....

I'll confess, this one went a bit wrong, and a long swathe of the animation ended up being 'underwater' as it were. So it cut short
I'm just speechless. Thanks for these Doug.
I love doing this with Google Earth. Hopefully we'll have enough data some day for the entire Red Planet.
Some DEM's are cool, some not so great. Cloud, ice, fog all screw them up (nothing to co-register for elevation I guess)

This one (attached - Arsinoes Chaos ) and a very long-noodle of Olympus Mons rendering now.
These things usually have an ND image of 12.5-50m/pixel, 4 colour images of 100-250m/pixel and an elevation image, usually of about the same res as the colour, perhaps slightly lower. Most of the time I drape the colour over the ND to super-res it.
With the Ol. Mons one, I thought "Do I drop the colour over the higher res ND filter?"
Then I discovered the ND is 17568x144800 - That's a full HiRISE image sort of filesize, and the HRSC to Tif convertor has to load the whole image into ram. So that's a no for now On the upside, I should be on 8 gig of ram by the end of the week (dropping 4 more in)
I want to do Elysium Mons, but the DTM is so soft it's a bit dull really.
How much vertical exaggeration do you have? As much as 5 to 1, I would guess. Could you try one without vertical exaggeration?
As I've said elsewhere, the vert exag is not an exact science yet - but it's far more like 2:1 than 5:1.

Even though I haven't downloaded all of these yet I can say that these are awesome. I'm surprised I haven't seen more HRSC animations - this should be great for PR purposes.
If only we had some HIRISE DEMs...
Just wanted to say how very much I appreciate these animations. I probably missed some earlier discussion but I was wondering, Doug, if vertical scale is a parameter that you can 'tweak' relatively easily, if (say) you wanted to make versions with no exaggeration?
I can change it very easily - and actually getting it right on 1x elev isn't too problematic either. I've not measured most of these accurately, but they're averaging 1.5ish - 2ish, that sort of thing.
! I was looking forward to something like this from you Doug, this stuff is very pleasing.
Is that 3dsMax-generated?
Yup - 3ds max, using the VRay renderer for displacement of the terrain.
Oly.Mons to be added later. It's a big noodle much like the very first one, but it's cool
Ah, THE mountain... I'm eager to see what's coming. Glad to know you won't be bothered with ram issues.
http://hrscview.fu-berlin.de/cgi-bin/ion-p?page=entry.ion will always let you look at them in 1x perspective. The problem is, 99% of them are dull as dishwater when you do that

Tonight - Eberswalde Crater with a CTX swathe on top, and maybe Nilli Fossae, probably without a CTX swathe on top.
They'll render tomorrow - and we're off playing Guitar Hero 3 tomorrow night, so they'll have to wait till Thursday
The texture for Eberswalde took for ever.
Just for you Nige - comparing 1x and 3x elevation at Nili Fossae (one of the MSL landing site proposals). Sat down, did the maths, made sure it was the right total altitude and that the difference between max and min altitiude matched the file headers.
I've actually set both of these rendering in full. The problem is getting the cameras to match exactly. (you can stretch a terrain vertically quite easily, but not the path that a camera takes) so not the exact same view, but it's the same frame number from two very similar animations.
You can probably guess which is the most accurate I can make to the actual, and which is 3x exag of that
For reference, this entire swath is 119.7km wide, 1059 km long - has a max altitude of -857m and a min altitude of -6866m (which I turn into adjusted altitiude based on the hrsc2tif idl module adding a value to make them all positive) - So a terrain altitude 'range' of 6 km from highest to lowest on the whole swath. i.e. 0.6% of the length - hence why they can be a bit dull.
Those swath dimensions refer to this entire box in which the map projected image sits - http://pds-geosciences.wustl.edu/mex/mex-m-hrsc-5-refdr-mapprojected-v2/mexhrsc_1001/browse/0988/h0988_0000_gr3.jpg - I create an alpha channel for the terrain to remove the crap off the edges, as the displacement process goes nuts with the edge of the elevation map ( hence all the little funky jagged hedges around the edge of most of these )
I think for maximum esthetic value you need something between 1.5 and 2.5. 1 is certainly too flat and 3 is rather tortured.
This is the first frame + a middle-ish frame of the Eberswalde anim - the landing site, very roughly, markes with a white circle (which vanished after 2 secs) - you can see the CTX swath in there. Sadly - I couldn't get 3ds to handle the 23k x 32k tif I wanted to use - so it's at 50% of that.
This + 2 x Nili for Friday probably.
Thanks Doug. So, EGD, Mars is too flat for ya?
And the HRSCView website will let you do that, to all the dem's they've got
I'm sorry that I don't share your delight. Not to shabby, but it's only animation, notting more. I prefer to watch real MRO's data (many times better) using IAS Viewer's functions "Create Waypoints" and "Waypoint following". For example, I suggest planning journey from west to east over Cerberus Fossae (PSP_003650_1900) with magnification 1:2. It's better and real movie.
Not everybody has the time to scroll through HiRISE imagery with the viewer, so Doug's work is highly appreciated here...
Thanks Doug, and keep it up !

Doug, is this the data you've already been using?
That's a great big mosaic of DTM's - most of which have not been released yet - but yes, it's the ingredients to those that I've been using
I've been following this thread for a while now. Since you posted at Celestia's forum. I'm impressed with all your clips. I noticed that the ESA is about to release more DTM's. Can't wait. I did an experimental model with file h0344. I created a short video while running Celestia and posted it on you tube. http://www.youtube.com/watch?v=zmrJYZxJmtY
I do have a clip with better resolution at my http://cartrite.myhosting247.com/site-pages/movie-page.html. For those running Windows this clip probably requires the xvid codec. There is a link for it on my http://cartrite.myhosting247.com/site-pages/movie-page.html.
I did a couple of others on you tube that uses the DTM h0344 from HRSC and uses a MRO CTX image as the texture.
Doug, I've just seen your 'White Rock' animation posted by Emily - very nice.
I'm annoyed that the DEM's that are available to download via the HRSCView site are clearly not as high fidelity as those used by the HRSC team to produce their illustrations. I'm not sure how or why, but they're just not of the same quality. But - given what's available, I don't think I could manage much better than that apart, perhaps, from using the MOLA set to give some context. I've been doing some renderings of mars as a sphere with the MOLA set and it's just breathtaking, even at the 1/4 of it's full res that I've been using.
Is it legal to resurrect a thread after 9 years?
