L3DT 16.03 dev build 2

Postby Aaron » Mon Mar 07, 2016 10:07 am

Hi Everyone,

A new developmental build of L3DT Professional (v16.03 build 2) is available on the Pro downloads page (see sales/registration e-mail for link). This version fixes the last blocking bug in the way of the next release, which was to do with memory allocation and exhaustion errors on large un-tiled maps, and maps with large tile sizes.

I would be most grateful if L3DT Pro users, and particularly those predisposed to making large maps, could download and try this version, and let me know how it goes. The larger the map the better. Go nuts.

Should this build get the all-clear, it will become L3DT release 16.03 some time later in the month.

Best regards,
Aaron.

Hi,

could you post some settings or something to reproduce?

I have a map (of Japan), which i could try to "resize", could take ~3-4 days till completion
File Size ~1 GB, resoulution 90m, 22465 x 24745 Pixel, 16 bit, tif File.

With or Without preimported HF Files?
From scratch, etc?

kind regards
Andreas

Hi Andreas,

Thanks for the question. I have no specific conditions to test, since the changes in this build are not to a specific calculation, but to the map memory management that affects all calculations. It would be perhaps beneficial to test calculations outside of the normal L3DT map generation process, as I've run weeks of continuous testing on those calculation and found no bugs. Resizing a giant heightmap definitely would fit that bill. If you're running on a computer with a bunch of cores and a truckload of memory, that would be nice too (my desktop is still only quad core with 4GB of RAM, so the behavior on better systems is untested.)

Best regards,
Aaron.

Thanks Andreas!

I've fixed that for the next build. I'm testing it now, and will post back here when available.

Best regards,
Aaron.

PS: How much disk space do you have?! That map would take over a petabyte!

PPS: Bravo, by the way. That was a good find.

Hi,


i didn't have a PetaByte, only around max 10 TB, it was only for testing ^^.
For the use with Unreal, I'm using only the map with the size of 224650 x 247450, cropping out the area which i want to use, modify it a little bit and than import it to Unreal.

kind regards
Andreas

Sorry, momentary brain failure. It would only have been a terabyte.

Hi Andreas,

Thanks again for the bug report. The fix is in L3DT 16.03 release candidate 1, which is on the Pro downloads page now (see your sales/registration receipt e-mail).

Hi,


didn't found any "memory allocation errors", in same or different session.

Tested as listed above.

(the 3. Point, to stitch the 42 Parts of Australia to one of them, i canceled for this tests, it would take to long time to report it here. But I try it ;))


kind regards,
Andreas

Hi Andreas,

I am most grateful for your efforts in testing the new build. I think we've sufficiently proved the stability of the memory management system under heavy load, so I'm moving ahead now with preparing the release of L3DT 16.03. Thanks again for your help!

Best regards,
Aaron.
