after more than a week ... no one any idea?

isnt it more than obscure if a computer with 8 GIG ram reuslts in a maximum of a little more than 2 Mio. Pixel maximum outputsize? thats a spherical pano of 2000 x 1000 pixel.
Hey i did bigger panos and I know other do it too ;-)) with a computer with 8 gig ram. So what does it mean if autopano does state:

Output size can not be larger than 2097152 pixels.

or is this a bug?
and what does it mean if it states:

Antighost will not be possible if you have moer than 26 pictures overlapped

and isnt it confusing if this number of allowed overlapped images (before Antighost is unavailable) increase but the total pixel size decreases and vice versa?

I can choose another cache division level to change values...
example using AUTO I can have 154 pictures per row before it gets slow (that plausible) but total pixelsize of pano may not be bigger than 524288 pixels. hey thats a 1000x500 pixel image, about 1/10 of one single source image?

Can other users with more than 8gig Ram review the settings and post a screenshot here like mine?

My personal statement: the displayed settings in APG are broken or complete misleading documented (online docu and inside APG)

Hi Georg
I have too "only" 8GB RAM.
And with APG 2.5 I do a pano up to 375'000x30'000 Pixels, 1440 images,144 in one row, with Antighost.
I don't try out this V3 alpha.
But is this calculated output size the total amount of pixels or the maximum width? Try it out.

And this 26 pictures overlapped, means maximum 26 pictures overlapped at the same time?
Normaly you have only 4 pictures, at each side one, that are overlapped.

But I remember such a case of restrictions last year. At that time, incorrect values in the settings where the reason.

Hi Georg
I remember a statement from Alexandre, that APG first reserved memory for the app and editor,
and only a portion of the rest for the rendering process.
At that time we discussed a separation of the rendering process to maximize the available RAM.


But I agree: kolor should explain these values ​​and provide for reasonable values​​. Then, some users would worry less

would be interesting to have a screenshot of a 32 and 64 GIG Ram Computer.... I would finally tip that APG for some reasons only requests (and works with)  50% of available memory....

Liebe Gruesse,
Georg

Prolably because I had some programms open in the background ;-)

dont thinks so (without having placed any trojaner on your PC to verify that ;-))) )
I tried to kill all available projecces on my PC from the windows process list... and even than with a "naked" windows autopano could only allocate 50%...

Hans: 16 GB - 11,4 GB = 4,6 GB (what use this space? Windows7 run on systems with only 1GB!)
Georg: 8 GB - 4,6 GB = 3,4 GB  , less than 50% of his RAM

George,

You might have helped me solve a problem that I had. I could not understand why sometimes my system would go into heavy swapping mode with the pagefile. Now I have a good indication that I should really keep the setting we are discussing a bit at the low side, so back to 9GB. This leaves my system enough RAM for whatever (including AGP) needs a bit extra.

I know it might sound every little bit logical but it sure smells good.

Thanks a lot.

what I also did figure out:

If I add autopano to the "Autostart" Folder ... its getting automatically started after reboot. Funny is that so more Memory could be reserved by autopano, obviously autopano got earlier the chance to assign/allocate memory... its not a lot, but without closing manually programms and stopping services APG couls claim 4119MB in my case.

so may be it could be an enhancement if autopano could place some "helper programm" at 1st position to be loaded and which per se claims all available (or set) memory.
So if autopano is later be started the memory is reserved since "long times" and now can be used by autopano...

Hi George,

I have 98,231gb of ram, and have 94,789 available... it says it uses 3.36GB 72 processes (currently 0% CPU usage), Physical Memory 3%

the amount of ram used also have to do with what devices it has to service, some devices are more intelligent, and they have their own CPU and memory to support themselves.

So me its just about adding more and more ram, I am pretty sure it was the same when I only had 48 GB

I hope this helps

Henrik

Henrik,

You are disgusting ;-)  98 GB of RAM, wow what a system. But heck, I agree with you that the more RAM the better. Georg has to look for a way to add RAM and then he can forget about many problems.

The moment I want to do bigger pano's then I am doing now I certainly have to replace the motherboard with something that can hold much more then the poor 16 GB I have to work with now....... for the moment it works fine, rendering is done while I do other stuff like sleeping so no hurry.

Hi Georg
I have a look at my Win7x64 system with 8GB RAM:
Startup APG 2.6.2x64 shows me 4.69GB possible RAM in the settings.

As you can see, with settings on "automatic" this is ok for a pano with 266 images in one row.
This is more than enough for a 360 degree pano with a 600mm tele!
Output size looks like the maximum width in pixels, but it's not clear at all. Kolor ???

At this point, the APG-process shows 4.3 GB private bytes.
The difference between Windows free RAM and APG is 1433MB.
To me this makes sense, this reserve helps so that the system can run further with APG

Kolor renders in lines, so if the total number of pictures IN A LINE or pixels on the longest edge exceed these limits your up the famous smelly creek without the paddle, if not Autopano will deliver. It may take it's time and your harddisk may go up in smoke, but the algorithm is stable.....and I leave everything on auto and do not worry to much.....and rendering in 8 bit using 8 bit tiff's also helps a lot.....and since a monitor nor a printer can handle more then 16.7 million colors.....that is quite enough......especially since rendering a larg pano is one thing, editing it in PS or Gimp is quite another.

Greets, Ed

Ed,

openning the "can of worms" of 8-bit vs 16-bit is different issue - do feel free to edit your images in 8bit that is your choice, but to advise it to others is a different matter, in particular if they are intending to do more editing after the pano has been stitched and rendered.

thanks for all the other info though!

Hi Hendrik
I see the same 524'288 Pixel max output size than on my system.
I wonder if this is a general limit in APG ?
Ok, it's like a 360 with a 600mm Tele, but ...

Dear Kolor Team,

please some short response to this issue...

is it an issue in kind of a software bug
or
is it an issue of understanding this settings/values wrong.

I mean I have 4gb free RAM and an output max of 524'288 pixel, and also Hendrik with 90gb free RAM does have the same 524'288 pixel?

Georg
