Yes, but this isn't the sort of thing you do when you start off.  I've
just checked and discovered two things:

1.  On a 15136x7568 pano with 20 components (the largest I do), the
intermediate files  took up 550 MB.  It's not clear that your
intermediate files are larger, since there are more of them, but
that could easily mean 2 GB in your scenario.

During stitching, the enblend image grew to about 8 GB, and I
could easily see you heading over the 16 GB in your scenario.  But
that's (virtual) memory, not disk space.

At the end of stitching, total disk space (intermediate and final
image) grew to about 800 GB.

2.  How much space was used in /tmp or /var/tmp?  None at all!  I
don't know where I got the idea that the intermediate files go to
/tmp.  So the question remains: what is getting written to the
root file system in Michael's scenario?  Michael, can you check
next time you stitch a pano.  The log window will tell you what is
being written, and where.  Maybe it's not /tmp at all.

That's not an unreasonable number. Hugin uses uncompressed TIFFs as
intermediary files, so a full sphere at normal SLR focal lengths could
have 30-60 intermediary files. Even more if you do exposure stacks. I
routinely exceeded my 16 GiB of RAM doing 3x15000 px 3-stack blends.

I think we have a disconnect here.  That's what I understand by
"create a (360°) panorama".

That second URL is a very roundabout way of saying the same thing.
But clearly you mean "how to animate a 360° panoarama".  There are
various software solutions, and we discussed some of them a while
back.  See
https://groups.google.com/forum/#!msg/hugin-ptx/2BRtxG3lSM4/MrLhTJedAQAJ
for one discussion.  Cartola (http://cartola.org/360/) does a lot of
this stuff, and may chip in if he sees his name mentioned.

Your URL is interesting, though.  I'll take a look.  My first
impression is that the online view is slow.

> People say you should use a fisheye lens

They do?

Yes, it should.  It also has the advantage of higher resolution.  With
a fisheye lens you get the whole scene in 6 photos.

I'm assuming the OP doesn't have /tmp mounted specially, so anything
that goes into /tmp is going onto the root filesystem. I know some
distros behave this way. IIRC, Fedora made /var/tmp a ramdisk but left
/tmp a normal dir.

This was just an example, clearly you'll need to modify the line to run
your specific job. See the hugin_executor man page for details on its
arguments.

The way I've shown here, the environment variable is only set for that
command invocation. If you would like to set it more permanently, add it
to your shell init (e.g. ~/.bashrc for bash).

If I recall correctly, the only reason Hugin would write files outside
of your destination directory is when temporary files are written. By
default it uses /tmp, however you can change that with the TMPDIR
environment varible like so:

$ cd /home/user/pano

[hugin-ptx] Using Hugin command line in Django web application

2016-09-14 Thread Krishn Bera 
I am making a Django web application which can be used to make and render 
180 or 360 degree panoramic images. The user will need to upload multiple 
DSLR images which will be stitched in backend and rendered as panoramic 
image on web page. I have no idea how to integrate Hugin command line to 
Django so that it can stitch the images in server once the user uploads 
them. Can I just install Hugin on server and have a script like bash 
running on server? Will it work? Any help regarding design or 
implementation ideas would be helpful.

People say you should use a fisheye lens but I just used my regular 
rectangular lens and it worked just fine.

I only test/use woa,  it works.

Only updated api-max.

What do you mean?

[hugin-ptx] Source code review

2016-09-14 Thread Bernd D 
Is here someone, who can check the following inconsistencies in the source 
code?

1.) pano_modify.exe calculate a wrong (vertical?) FoV.

 %HUGINSDK%/hugin-hg/src/hugin_base/algorithms/nona/CalculateFOV.cpp
function hugin_utils::FDiff2D CalculateFOV::calcFOV(const PanoramaData& 
panorama):

if(fov.x<40)
{
fov.x+=1;
fov.y+=1; // [BD] I add this line, so that y is equal to x treated
};
return fov;

fov.x and fov.y must be calculated equivalent. What reason is there for the 
if statement? The gap at 40.0 make no sense. It looks like a dirty trick to 
bend the correct result to a desired result. I use always fov < 4, then it 
seems to work better with +1. But this is only a subjective impression.
 
2.)
 %HUGINSDK%\libpano-hg\math.c
function tiltForward:

 
   s = z1 / z0;
   s = z0 /(x_dest * (-sin(phi2)/cos(phi2))  + y_dest * sin(phi)/cos(phi
) + z0);


The first calculation of s is unused. Perhaps an unnoticed error.

Kind regards,
  Bernd
