So you are saying it is better to have Windows take care of the Swapping as virtual memory? Then something that could be built into Photoscan.

Well maybe there is a faulty memory in my system.. been running a test on the RAM.
Might be the reason for the error, I still would like to see a cache option in Photoscan.

I used WinDbg to take a look at the BlueScreen dump file, in the bottom it states.
Code: [Select]
Probably caused by : ntoskrnl.exe ( nt+3ceb8 )

General / Cache directory in Photoscan
« on: April 05, 2012, 01:08:44 PM »
When working on larger projects where more RAM is needed towards the end of the Meshing would it be possible to have a caching directory in Photoscan to cache to instead of using the Windows Swap file, most software is set up this way.
Reason I am asking is I have assigned swap file in Windows but Photoscan keeps on bluescreening when it starts to swap.
I know it will be slow, but processing can then be done on larger sets, there are fast SSD solutions out there that can be used.
So could you please add internal Cache/Swap to Photoscan.
Does swapping from the GPU cause any problems maybe, is that why I get bluescreen?
P.s. I have 64GB of RAM but I am still running easily out of RAM. And there is not really any indication how much more RAM I need.

And, actually, if you use Ground Control before meshing will it be faster at meshing as it will know that only x many images are visible in each section of the mesh, or will the bundle adjustment have already taken care of that.

So I add to this question, if the images are aligning fine using 100.000 points per image is there any reason to use 200.000 points or more. Or should I even use less to speed up the process.
Yes I changed the max to 200.000 in preferences, and it is finding 200.000 points per image just fine.
Will this have any impact on the Meshing, or accuracy of the model in any way...?

You do get the option of doing pair selection in Align images if you have ground control points in the images before.. but still wonder if it does change anything in the process.

I would look into getting a Canon 5D Mark II and a 24mm TS Mark II lens...
Or look at the new Nikon D800 or D800E, not sure what lens to look for there.

Does it matter if I add GPS iformation per image before or after the align images is run?
Will it improve the alignment?

« on: April 02, 2012, 01:18:14 AM »Oli, you must be a first tester. from what i know from Agisoft, reconstruction routines use single precision arithmetic, that mean the 680 could speedup the process. But still need someone with the card..
I think I will stick to the 580 card for now, I might just get another one of them as they should get cheaper now being an "old" card now.
What about the Nvidia Quadro cards, are they outperforming the gaming cards in Photoscan or is it the other way.

« on: March 23, 2012, 12:24:14 PM »I see the results but I don't believe it... can they fix this with better drivers or is it fubar from a hardware perspective in relations to compute capabilities?
Well what it looks like is Nvidia is crippling the gaming cards in the Computational calculations in their drivers... One reason sell more Quadro and Tesla cards. I think its the most stupid move on their behalf.
If that is true, about it being software, as in on the driver side. Then there is allways a change of someone making hacked drivers. Like these. http://www.omegadrivers.net/
Sadly the guy behind the drivers can not keep developing, due to the recession.

Well if this is all true it might be worth just to get another GTX 580 and have two of them.
I need CUDA for other projects so AMD is a no go for now at least.

LOW - 168 MB
Medium - 390 MB
HIGH - 950 MB
so a ultra will use much more memory, that mean a lot of RAM - CPU - GPU - GPU mem transfers. best app for that http://www.ozone3d.net/gpushark/ and set detailed info...... Could test it someone
Seems like I am getting a Max of about 800MB on the GPU when using ULTRA with 21Mpix images. So its not even getting close.
