last Friday Phil Plait over on " Bad Astronomy "
posted a cool image

http://www.slate.com/blogs/bad_astronomy/2016/03/25/conical_structure_on_mars_in_a_sand_dune_field.html

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

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.

How much vertical exaggeration is there in your renderings?

Posted by: Sean Jan 6 2017, 06:31 PM

None. This is straight from the DTM.

Posted by: scalbers Jan 6 2017, 06:42 PM

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.

Posted by: Sean Jan 6 2017, 06:49 PM

Its on my list Steve, this initial splurge was spent optimizing the workflow. I managed to shave a few hours off!

It's Uzboi - I know that place. laugh.gif

I'm used to looking at a lot of HiRISE images, and with that perspective, the first one in colour looks spectacular (and they are all quite informative - something to keep in the back of my mind the next time I look at related 2D images).

As usual...no vertical exaggeration.

Still lots to improve on... atmosphere, colour, animation etc.

DTM suggestions welcome.



Posted by: scalbers Jan 8 2017, 08:29 PM

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"

Posted by: Sean Jan 8 2017, 08:44 PM

Thanks Steve... I love that Carl Sagan idea!

I'm currently working on a Curiosity shot so watch this space!

Seconded. These are phenomenal.

I particularly like the lack of vertical exaggeration.

Thanks Sean.

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.

These are great Sean, have subscribed to email alerts this sub-forum so I dont miss any smile.gif

Fingers crossed there is enough data that will enable you to create a few of Gale crater. If I could be permitted to throw an idea your way, maybe one of the entire path from landing from an elevated camera position, with tags on the ground for the rovers position every 50 sols or so?

I'm working on Gale but its a big job and I want to do it justice... I'm filing the edges off the workflow with these posts.

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?

Posted by: Sean Jan 15 2017, 03:56 PM

Its on the list Steve. Although given the limited coverage of the area I wonder how much atmos to add.


Posted by: scalbers Jan 15 2017, 04:28 PM

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.

Posted by: Sean Jan 15 2017, 05:05 PM

Thanks for your response Steve. Horizon haze is on the to do list as a priority. smile.gif

To re-iterate, these are simply spectacular Sean - almost Ansel-Adamesque. Thanks for sharing them.

Posted by: Sean Jan 19 2017, 07:25 PM

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!

I understand the addiction. Years back when I was knee deep in the Microsoft Flight Simulator I found that users could add photorealistic scenery to areas and found DEM files from NASA and aerial photography shots from my county and combined them together to make the Phoenix area I was always flying over more realistic. The results were stunning. Suddenly the mountains and riverbeds looked exactly like reality and I began creating 3d buildings and objects, taking photos of their exteriors and wrapping them over the vertices. I spent months adding more and more. It eventually ended up a side business as people convinced me others would buy my work. It never was about the profit though. Was about the creativity it unleashed. A major addiction when it all comes together. Your work is wonderful.

Posted by: Sean Jan 20 2017, 11:30 AM

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...

https://flic.kr/p/RcZY1X




Posted by: Sean Jan 20 2017, 01:08 PM

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...

https://flic.kr/p/RkoGKd

...shots closer to models would hold up better though.
