Slow rendering:(

Hello Guys

I upgraded to APG 3some days ago and i really like it, BUT i do have a problem.

at the moment i am stichting a 661 pic planar Panorma, shot with a 300mm fixed focal lens on APSC ( 450mm on 35mm Film).

Setup:

Intel i7 2700k 3,4Ghz
16GB Ram
nVidia Geforce 570



Yesterday i did a "partial" stitch with around 400 Pics and it worked very well (like almost always). I chose to render a 25% output and it was still a 900mb tiff file. I needed around 10-15minutes, maybe 1hour.

But today i finally tried to stich together the "final" result.
At first i rendered a 10% output which is around 14000x 1500 pix. but it need very very long.

Then i tried a  25% output, which is still not ready and is at least rendering for 3-4h sad

Some pics now have an alternate Filename, like "Pic1312_corrected" an i dont know why not all pics have this corrected version of themselfs and why it is soo slow sad

PS:
and autopano always resets the temp folder.
i have a dedicated hard drive für thinks like that ( temp things, caches  etc.) but almost everytime i restart autopano it is reseted to some ...Folder in C: AppData.

Re: Slow rendering:(

Hi Mehlsack,
my old laptop (4gb ram, intel 4 core) takes more than a day for a 660 pic rendering at 100%. So be patient.
15 minutes for the 400 pics 25% is a great time.

You should have a look at the settings, cache division. Set it to a value so that the "pixel size" (in german: Ausgabeformat kann nicht größer als XXXX Pixel sein) is a little bit larger than the resulting x-axis of your pano. You see the pano size of your project in the main window. If there is really a resource problem on your pc, you should suspect the cache division first.
After changing the value apg must be restarted.

The reset of the temp folder sounds like a problem with file access rights. Reinstall of apg?

greetings from Wuppertal to somewhere else in germany
Chris

Re: Slow rendering:(

Could indeed be a temp-directory issue. If the first/fast directory is full, AP continues on the second one which problably is not as fast.

Re: Slow rendering:(

Re: Slow rendering:(

Why?

At the Moment a HDD has a higher IOPS Count (which isnt so different anymore).
The HDD is just for caches (like lightroom, PS etc.) so if it really would break down i will happily switch to a SSD big_smile

If you use the HDD for cache only then the damage is of course limited.
