I'll step up to the plate.  I'm a recent Mac convert and I'm already
building Hugin, Enblend, libpano and autopano-sift-c from CVS, so all
I should need help with is the packaging.  Feel free to point me to

[hugin-ptx] Re: Hugin for CA removal

[Harry van der Wolf]

Hi Hein,

I have never used fulla myself. These tools are built by Ippei over a year
ago. I was too lazy to rebuild them and was planning to do that after the
0.8 release (but that's not going to happen soon now).

They were build as static binaries, meaning that "everything" needed
(libraries) would be linked inside this one binary.
Obviously this is some bug in fulla that is now showing up. It has nothing
to do with a violation of a contract. It is simply an error message by the
program stumbling on some part of it.
Don worry about perfroming illegal activities or using illegal software: Not
at all.

Harry

  I agree.  I am far from a first timer, yet I like using the
automated assistant.  It seems to work as well for most images as
would a manual placement of points, optimizations, etc., and a lot
faster.  But, an option for the default preview window would be
beneficial for any user.

[hugin-ptx] Re: OpenGL slow because of reloading

[Harry van der Wolf]

Hi Habi,

The most prominent change is that the OSX RC5 bundle is 32/64bit. You run it
on a macbook pro and I suppose with Leopard. It means that it will run in
64bit mode and use a 64bit address space. I think the enblend problems are
related to the earlier 32bit versions. The 64bit enblend can allocate far
more memory than the 32bit.
It should(!) function correctly on 32bit, but malloc on OSX is not very good
and leaves many chunks of memory behind. The 64bit version can allocate much
more memory. I assume it is therefore "more forgiving" as it has more memory
to use as garbage bin before choking itself in it's own garbage.
It means that the Hugin builds in future should be preferably 32/64bit for
those who can run in 64bit.

Who will build these bundles?

Hoi,
Harry

You can't at the moment.

The reasoning for this is that the Assistant only automates tasks 
that can be performed in the other tabs.  A 'wizard' should have 
good defaults and not present confusing options.

It seems that it isn't just 'first timers' who use the assistant, so 
it is probably appropriate that stuff like this should become an 
option in the preferences.

e.g. some Assistant users would prefer not to see a preview at all 
and others would like to send the project to the batch processor 
instead of stitching immediately.

I can partially reproduce this.
I *am* able to click the last image in the list, but the blue  
background does not move down to the last image. But clicking it loads  
it just fine.
And additionally I've also got the empty space at the bottom of the  
drop-down list, both can be seen here: http://www.screencast.com/t/PvcEy32xPG

My MacBook Pro has 2GB of RAM, and i could only upgrade it to 3GB if  
i'd swap one 1GB for a 2GB module, something which will come after the

The previous reports for this bug suggest that it happens when the 
width of the output is greater than 32768 pixels.  It would be 
useful to prove or disprove this.

Some interesting tests would be to:

Try again with the output at 47543x100.
Try with the width at 32000 then at 33000.
Roll the panorama 90° using the numeric transform in the preview and 
stitch a 8381x47543 panorama instead.

Seems that something external stopped the process, maybe an oom

Have you tried --visualize=visu.tif or some other TIFF name?

That is a difference between the two projections.  'yawing' a 
cylindrical panorama has the effect of simply shifting all the 
pixels to the right or left, though in reality you are rotating the 
scene.

Here in the Netherlands in Zwolle where I live we luckily have a big Apple
service firm which does sell second hand refurbished macs as well. Normally
they always have a good set of refurbished machines. Currently they have
absolutely nothing and I'll be on holiday for 4 weeks. After that I'll check
again (and maybe have to wait longer).

I will see what happens.

horribly upset were my Mac to suffer a similar fate.  All I can do is
offer a few thoughts since I do not have a modern Mac that I could
provide to you.

  Look on Craigslist for something used.  I got my iMac desktop
machine from Apple as a refurbed unit and saved a goodly amount of
money.  I recently obtained a Mac Mini from Apple for a friend of mine
and got it for $400 (US) including a very nice Canon printer.  Apple
has deals like this on a occasion.  Put Linux on a Mac.

  At any rate, I feel for you.  Good luck.  I'll miss your builds.
And this is happening just as I got back to the list after having to
move in January, getting a new e-mail address and finally getting
around to re-subscribing.

[hugin-ptx] (Temporarily?) no more MacOSX Hugin builds from me

[Harry van der Wolf]

Hi mac users,

*Sometimes shit happens :(
*
Friday evening I baked my macbook. I connected an external USB disk, with
it's own power supply, to my macbook. A sharp electrical crackle with an
accompanying mini lightning flash and both my macbook and that USB disk died
immediately and were completely fried. Both smelled terrible. The power
supply of the disk caused some short circuit power in both devices.
A quick repair of my macbook would be at least 400 euro's (main board
replacement) but most possibly 500+ euro's. A possibly cheaper repair by
cannibalizing parts of other macbooks could be cheaper but take at least a
couple of weeks (due to summer holidays and currently missing parts).

I used to be a convinced Linux user until I got to MacOSX in May 2006 when
my very old Dell laptop running Linux died. I was given a macbook by someone
who likes me very much. That's how my OSX adventure started. Being a Hugin
user on Linux, I wanted this on OSX as well. Ippei Ukai was working hard on
OSX improvements (and did a very good job) and  he also built bundles. But
he did not really keep up "the bundle building" with all the new
developments in my opinion. That's why I stepped in, which was also a good
way to share the workload.

As mentioned, the repair of my macbook costs more than a new basic model
amd/intel "pc" laptop, which is all I currently need and want. That's why I
decided to buy such a laptop and get back to Linux (immediately sanitizing
the disk from terrible Vista).
I think I want "some" mac back, but it might take months (macbook or iMac?)
as I need to decide whether I want the macbook repaired, buy a top model
iMac or ..? (and I'm 4 weeks on holiday starting somewhere next week)

It simply means that I will not build hugin bundles anymore for an uncertain
time (weeks or months) as I just can't do that on Linux. The "timing" is a
bit awkward just before the final 0.8.0 release, but I can't help that.
Someone needs to step in to start building OSX bundles again. I will do
everything I can to support the new builder(s), but (again): *someone really
needs to step in as bundle builder.*


FYI: I immediately built the RC5 on Linux again , with all it's whistles and
bells.

Note: what bothers me most is my own ImageFuser, which I use frequently and
can't use any longer until I have a another mac. And there is no substitute
either on Linux. I used to use Kommander
occasionally on Linux. Maybe I start
a KImageFuser "project" on Linux.

Hoi,
Harry

Hmmm, this is an equatorial mount only. The barn door is a drive 
actually, which allows for compensation of the earth's movement. You 
find a couple of step-by-step instructions in the google search results 
of above link.

I think I get it. You are requiring that we can write the remapping
function as a polynomial in x and y, not just in r. That rules out
using odd powers of r, because " r=sqrt(x^2+y^2) cannot be written as
a polynomial". Even powers of r can be written as a pure polynomial in
x and y.

I appreciate the theory presented here, but I think we have drifted a
bit from some practical considerations. I suspect it would be a large
amount of work to change or extract the distortion equations from the
Hugin / PanoTools toolchain, across the multiple tools that use them.
So any developer or Google SOC student :) which might undertake this
would need to be convinced of the benefits. In theory, the benefit is
numerical stability, and matching best-practice academic research in
this area. However, are there practical examples of PanoTools failing
or acting badly because of its distortion model? If this change can
solve real-world problems, it might be worth it

Aron

Thanks Steve.

If the 'aligning images' message comes up then celeste should have run 
successfully, but I'm guessing it has done something strange like remove 
too many CPs for alignment to work. Any chance you could send me the

  I just tested this again to make sure I have everything straight.
The crash usually occurs just as the "Aligning Images" dialog box
appears, which is immediately after Celeste has finished running.
Sometimes it will crash while the Celeste progress bar dialog is still
being displayed, but is probably not really crashing until Celeste has
finished its run.  I then get the same "Hugin has unexpectedly quit"
dialog as one gets when quitting the application after having used the
Fast Preview window.  It makes no apparent difference what control
point placement routine I use, Pan-o-matic, Autopano Sift, etc.

  No crash under the circumstances you have outlined above.

Hi Steve,

During the celeste related crash, what is the last message in the 
dialogue box that says "finding CPs, running celeste, aligning images etc"?

Can you also try not running celeste automatically, and instead 
selecting all the image on the images tab and running celeste from 
there, then going to fast preview. Do you still get a crash?

Cheers,
Tim

  This is a long running situation that does not really create any
operational problems since it only occurs upon quitting the
application.  I think it has something to do with the Open GL graphics
engine.

I'm not quite sure. The MS guy who is in charge for their Photosynth
software actually released code from his research projects under GPL.
We'll see :)

I do know however that information in the Adobe related papers is not
always sufficient for creating software. The one from seam carving was
(wasn't Adobe at the time, though), but the one from PatchMatch

[hugin-ptx] Re: hugin-mac-0.8.0-RC5 32/64bit version released

[Klaus Foehl]

Hello,

A quick bug report, yes I know it should got onto the bug-tracker as
well, but work comes first.

Mac mini Tigre 10.4.11.

1) Control Points tab, in the drop-down menus with the images one
cannot click on the last image. Ist also appears that there is extra
space in the drop-down panel below the last image entry. Work-around
exists, as one can move the highlighting on the image list with the up/
down-keys.

2) Blending section of stitching: had "--visualize visu.jpeg" as
default option from a previous 0.7.0 option but stops stitching
progress as file somehow cannot be written. Same for suffix .jpg. Have
not tried yet absolute paths (IIRC was not necessary in the past,
maybe I had an external enblend somewhere then).

3) On quit: program hugin terminated unexpectedly. As long as nothing
more serious happens than needing to click on "close" ok by me.

Regards

Klaus

P.S.
a) Drag works differently with rectilinear and cylindrical
projections. With rectilinear I only get rotations, no shifting.

b) The new output cropping tool works rather nicely. No need for post-
processing most of the time.

[hugin-ptx] Re: OpenGL slow because of reloading

[Guido Kohlmeyer]

Dear David,

regarding your comment "albeit it took approximately 5 hours to render", I
expect you can speed up the calculation with more RAM. After upgrade my
machine from 512MB to 2GB RAM the process was very quick compared to the
less RAM configuration, especially enblend benefits from lot of free
memory.
My panos are commonly 14000x7000px built from about 32 pictures in
eqirectangular projection. The enblend step needs about 1.5 to 1.7GB RAM
to run quickly, otherwise enblend goes to disk with slows down the
process.

[hugin-ptx] Hugin 0.8 rc5 fast preview and celeste

[Steve Rigby]

   I have two things to mention as related to the subject of this  
message.  Firstly, how do I turn off the apparently default selection  
within Hugin of the Fast Preview window?

   Secondly, I am having a difficulty using Celeste in conjunction  
with the Fast Preview window when I have set Celeste to run  
automatically after the generation of control points.  Hugin crashes  
in this situation, though this behavior may be erratic.  I'll have to  
look at this a bit more in depth, but was wondering of anyone else is  
seeing something similar?

   I am using an iMac, Core 2 Duo and Leopard 10.5.4.

   I see that the "Hugin has unexpectedly quit" situation remains  
after using the Fast Preview window.  This is not a problem for me,  
just an observation of a long term iissue.

   Steve
