last Friday Phil Plait over on " Bad Astronomy "
posted a cool image
it took the weekend to process all 18 HiRISE red ccd images into one mapped image ( 1.3 gig )
then run a SFS on it , well a crop but still 8192x8192 image
reduced size ( 2048x2048 mesh ) test renders in Blender

Here is a selection of renders from recent HiRISE DTM's...
Really nice renders Sean! With this I can imagine rover visits to each of these places. Would be interesting to see where you are in Noctis Labyrinthus relative to the context say from some Viking images that I recall.
Thanks Steve...http://www.uahirise.org/PSP_009118_1665 is the location...
and a test flight...click on the image to see the video.
*edit*...and another of the same area, click thru to see the video...

last two for this batch...
How much vertical exaggeration is there in your renderings?
None. This is straight from the DTM.
Indeed glad you are faithful to the terrain - and besides vertical exaggeration wouldn't be needed anyway!
One thing that might be worth a try sometime is the inclusion of scattering by atmospheric dust, depending on how much in the way of the optical parameters can be included in the rendering software.
Its on my list Steve, this initial splurge was spent optimizing the workflow. I managed to shave a few hours off!

No vertical exaggeration.
These are just spectacular. I hardly know where to begin. Thank you VERY much, Sean.
Thank you very much, I'm having a LOT of fun making these.
I will be introducing scale reference into the images and here is a sample from the next video I will upload soon...
Here is the video with an Astronaut scaled to the model... Click thru to check it out.
As usual...no vertical exaggeration.
Still lots to improve on... atmosphere, colour, animation etc.
DTM suggestions welcome.
Thanks Sean for really advancing things on how we can view Mars. As for DTM suggestions one can consider a helicopter style view following the tracks of Curiosity, Spirit, and Opportunity?
Another one (unless you've done this) would be in Valles Marineris, harking back to a passage from Cosmos where Carl Sagan narrates a fly through animation poetically saying "...careening through the corridors of the Valley of the Mariners"
Thanks Steve... I love that Carl Sagan idea!
I'm currently working on a Curiosity shot so watch this space!
More Mounds... these are rendered at full available fidelity in the model and texture to determine qualitative difference compared to the previous 'optimized' versions.
Thanks, I'm glad you are enjoying them.
If you are familiar with a nice location covered by DTM then please let me know and I will see if Astrid will pay a visit.
SE Asia, Australia, and Antartica are in view. A calibration image taken November 2016.
Here is a video from the same location as the previous post...
There is a to-scale astronaut in the following image...
Thanks for this challenge. Great way to inspect this incredible terrain. (Or should that Arerrain?)
So it turns out that this area is Domoni crater and the nice folk at PIRL let me know that HiRISE had full coverage so I was able to extend the scene in 3D to provide the following images...
using these assets...
Thank you for sharing these!

Can you spot the astronaut in this image?

Amazing how much detail there is in all of these DTMs that Sean is bringing to life. I'm curious about what the brighter material is near some of the higher terrain. Nice to see an atmosphere showing up in the background. I wonder if future plans might also consider the effects of the atmosphere between the observer and the terrain?
Its on the list Steve. Although given the limited coverage of the area I wonder how much atmos to add.
Interesting question Sean. For a ballpark answer I would suggest that we can estimate an overall optical depth tau (~0.5) and dust scale height of 11km. This means the extinction coefficient at elevations near the ground would be 0.5/11km or 4.55 * 10^-5 m^-1 (tapering off exponentially as we go upward). From this both the inscatter and outscatter can be determined in the path between the observer and point on the terrain.
The impact might be subtle in the foreground, though becoming more noticeable for distant features in the background when looking near the sun.
Thanks for your response Steve. Horizon haze is on the to do list as a priority.
Here is a still from a forthcoming animated tour of Hale Crater Hills.
Added some atmospheric scattering.
Another one from Hale Crater Hills...
Great to see this realistic atmospheric effect!
Thanks Steve... I figured out a way to automate/bake it into the workflow so it should help a lot with future images. More work to be done on the skybox.

Stitched together from 2 DTM's.
Hale Hills oblique...
rendered at 20000 x 10000
To re-iterate, these are simply spectacular Sean - almost Ansel-Adamesque. Thanks for sharing them.
Thank you, quite addictive making them! The data is amazing...these renders are optimized to run on my machine so there is room to squeeze a little more detail out. There are lots of 'improvements' on the way...sky, colour and hopefully some kind of contextual compositional solution, if I can get my head around the myriad sources!
Thanks for the story Art and given that your compliment means a lot!
I suppose it has something to do with making these inaccessible places tangible in some way, there is a visceral thrill when the elevation data & satellite imagery come together. Suddenly it is a place.
Here is a best quality available video of RGB pass from the Mounds in Ganges Chasma...
Now able to render at full available texture resolution!
A small breakthrough which might only result in a tiny perceptible qualitative improvement given compromises on elevation data...
...shots closer to models would hold up better though.
Here is RGB data mapped to 3D model to show parallax...
Culled this animation from a 9 DTM strong swathe of Mt Sharp... too wieldy to be productive yet so the following uses only 1 DTM
click thru to see the video...
Hematite Ridge portrait
5 DTM's at full texture res, 12k x 6k work in progress so please forgive the misalignment!
Click thru for the video...
Here is a link to a 450 megapixel test render of
over at Gigapan.
Rendering at this level shows up some errors in alignment & textures ( not loading ) but is a good prep for upscaling to 65k pixel output
Any chance you point out where's Oppy or where she'll enter the scene? Thanks
Here is a link to another Gigapan 450 megapixel extravaganza...
And the Flickr version...
I was quite aggressive culling the DTM borders to conform to the chosen viewing angle.
Lots of work in Photoshop to balance out the jigsaw of exposures.
Each of the 5 DTM's were rendered separately, the foreground render then acted as a guide for conforming the rest to the base Mt Sharp render which is visible in the background crater rim and the upper left of the image. A depth pass was used to introduce atmosphere and soften transitions.
An amazing dataset!
You mean Curi, surely?
In the most recent Gigapan you can see Murray Buttes at the bottom center right of the image, tracing the route up toward the natural break in the dune field to the left of Ireson hill you can almost discern a path leading up to Hematite Ridge. In time I will make a version with the notional route.
Thanks and haha! Yes Cury, don't ask me why? May be Oppy=hematite for the last 13 years
The Gale Crater movie is perhaps the most awesome rendering of planetary image data I've seen. Thank you! It really brought the places Curiosity is exploring to life, which the overhead images don't.
If you ever have the time and inclination, it would be fascinating if the movie could retrace the Rover's journey.
Thanks vjkane, although to be fair there have been awesome animations using the same data over on Youtube since 2010.
I do have a nice 4k animation cooking at the moment but its going to take a while before it is ready.
In the meantime here is another take on the HiRISE coverage of Mt Sharp...
and the 450 megapixel Gigapan version...
I grabbed a crop of Sean's "Mount Sharp Northwest Flank" (from Gigapan) and roughly marked Curiosity's route up to sol 1589 (green), it's current position (yellow star) and the latest "notional route" from JPL (red). Hopefully it will be helpful. Sean's work has added another dimension to my awe for this mission.
Thanks Fernando. The wide field view of Curi's journey is a sight to behold!
So my plan is to image the entire mission zone along with the route so far & notional route, in as big an image as Gigapan will host, I'm not sure what their upper limit is. I think Photoshop will only go to 65k pixels square.
The trick will be to get a good angle without making the quilt-work of DTM's too obvious against the lores mesh of Gale Crater.
Here is a 4k video covering a 4 DTM swathe of Mt Sharp
Each DTM was rendered separately then combined in After Effects to blend variable exposures.
