What was amazing was that just the very tip of North Knob was visible - and bingo, the Viewshed called it out perfectly.

just out of interest, here are a few quick views of the pathfinder area ("twin peaks" and the area immediately surroundig the lander) rendered using the single-image shape-from-shading (SFS) method described in the other thread ...

although the SFS based DEMs are probably far less accurate overall than the near perfectly precise official stereo/altimeter based HiRISE DEMs, it is still amazes myself how much 3D detail can be squeezed out from a single image already...

I'm having some problems with the DTM .IMG files from the HiRISE site. It seems like the same (or similar) problem I was having back in page 4 of this thread.

I'm using the latest version of FWTools (2.4.7) and I can open up the .IMG in OpenEV. But I can't convert it to a .jpg, .bmp, .gif, or a .png file. It just says "unable to create output file...". When I try converting it to a .jp2 or a .tif file, it appears to work, but when I open the exported file into photoshop, it's completely black in the .tif file and completely grey in the .jp2.

Does anyone have any idea what's going on? Is there something I need to do to it before exporting it to another file format?

Use Bjorn's latest version of img2png - it'll turn it into a PNG for you.

Seems like the video's are still entrancing new fans, just noticed Gizmodo picked it up via Twitter from Roger Ebert.

Edited - I just noticed Emily's comment on the Discovery article regarding the attribution of the video and corrected my own mis-attribution. Hangs head in shame.

Yup - it's Adrians awesome work. Mine don't look anywhere near as good, and mine take minutes per frame, rather than 30 frames per second.

I've emailed the Gizmodo writer, commented at Discover, hopefully they'll get the message and correct it. Adrian is the one who deserves the credit for this, not me!!

New DEMs have been posted on the HiRISE website here.
Maybe some of the imaging wizards on this forum can use them to create flyovers, oblique views... I wish I could try it myself, but I don't have the tools to do it, nor the time to learn how to do it (there's a thing called "work" that gets in the way). I know everybody here has his own occupations, so I understand that it's not possible to fully exploit all those goodies.

Hi all, I've finally had enough free time to do some more animations based on the HiRISE DTMs. I hope you like them.

Mars3D:

Finally I downloaded your animations (HD) and with proper music, it's really ecstasy!

Thanks for kind words.

I have uploaded some more videos, these ones are in 1080p format.

They were created from DTM's I've used in previous animations but the paths are different.
Mojave
Athabasca
Dune Avalanche

You'll need to manually select 1080p for the best quality as it usually defaults to 360p.
