After much experimenting (thanks to the improvements in v1.0.1) I've found these settings work well for the anaglyphs:



However, looking at it now, I should change the order of the generate color to have the L4L5L6 combination as the first choice...

If you find better settings for the anaglyphs, let me know...pancam at 0% gives best depth of field (though nothing really helps the anaglyphs of the sundial...)

I agree; in 1.0.1 I changed the generatePancamLeftFalseColorTypes default to this:

L4L5L6,L4L5L7,L3L5L6,L3L5L7,L2L5L6,L2L5L7,L2L4L6,L2L4L7

But it doesn't automatically take affect for people who are upgrading, your old settings stay around. So you might want to make this change manually.

Midnight Mars Browser is stalling with a "Java Heap Space" error. Win2k, sp4. Java 1.5.0. Does this after downloading quite a few images.

MizarKey, I'm trying those anaglyph settings now, they seem to work pretty well on the whole. I may even switch to those for the defaults.

MahFL, I've been hearing scattered reports of out of memory problems on long downloads, I'll have to look into it some more. At least we're getting an error message now (before it would have just hung).

Is it possible to allow a negative number for the Pancam Anaglyph setting? I tried to use -0.03 but it said the number had to be between 1 and 0. I think it could benefit from being less than 0.0, though 0.0 does ok for 'long' views, anything close to the rover is still not great...maybe for the next version, if it is possible at all.

Thanks,

Version 1.0.2 adds the abillity to update images from the JPL site, and hopefully fixes the remaining out-of-memory errors.

I'd appreciate it if some of you folks who were having out of memory problems would let me know if this works for you now.

Thanks a lot! Excellent timing, I was starting to check exploratrium every hour like some addict blink.gif
I thought I was going to have to download files one at a time from JPL.

bug report: It checked for forward hazcam images on sol 410, didn't find any, moved onto the next sol, missing the pancam shots for that day.

I downloaded them one at a time and was wondering why it didn't turn them into anaglyphs until I noticed they were L2 R2: add ,L2R2 to anaglyph types.

I hope people will be sensible when downloading data from the JPL RAW website.... it may be just a coincedence but i've had lots of problems accessing exploratorium since users started downloading massive amounts of data - and now the site is no longer updating at all. smile.gif

Regarding the bug report, are you sure it didn't download them? The "Update Latest Images from JPL" option downloads things in kind of a goofy order (by camera, and backwards by sol), because it's actually scanning the main page for the rover and looking for sols marked *NEW*.

Regarding the L2R2, I noticed that, it's on my list of "Things to Get To". Fortunately you can fix it yourself, just be sure to put it after L7R1.

I agree with people using common sense, and I put the download from JPL feature is there mainly so Exploratorium doesn't get too overwhelmed if this program ever becomes popular for some reason. Without taking anything away from the great job Exploratorium is doing, however, (donate, donate, donate), I've noticed this kind of outage several times before, long before MMB ever arrived on the scene.

On a related note, I'm trying to contact JPL at the outreach address just to let them know the program is out there, but if anybody knows a better contact (or perhaps *is* a better contact) feel free to contact me at midnightmarsbrowser@mac.com

Now i'm confused, could you let us know the recommended parameters,
i have these values for the preferences:

OK the update latesst images from JPL option downloads them. I had used the advanced update from JPL option, I got java.io.FileNotfoundException:http://marsrovers.jpl.nasa.gov/all/spirit_f410text.html;terminating. after which it went onto the next day

That all looks good, the only difference would be to change the generatePancamAnaglyphsType from L7R1 to L7R1,L2R2 to pick up the latest anaglyph pairs from Spirit, which happen to be L2R2. You want to make sure you put L2R2 *after* L7R1 because L7R1 is a better choice generally. The generatePancamAnaglyphsTypeMax=1 setting means that only the first matching anaglyph type will be used, but if you put L2R2 first the program would generate a bunch of new L2R2 which already had L7R1s generated, because it doesn't delete any existing generated images. You wouldn't really want that, generally, so just leave generatePancamAnaglyphsTypeMax set to 1 and change generatePancamAnaglyphsType to L7R1,L2R2. This change will probably be made automatically in the next release, if you don't want to bother with it that's fine.

Does that make any sense? I promise I'll document this stuff some day...

The java.io.FileNotfoundException is actually okay, that file really doesn't exist and it's not supposed to (assuming there are no forward hazcam images for that sol). I knew I should have changed the message to something more friendly, as it would cause confusion, I just didn't get to it. Apologies; I'll fix it in the next one.
