I have also noticed this (Linux x64). It has happened since the OpenGL
preview was added. It renders the OpenGL preview useless; the only
solution is to close and restart hugin. However this bug is hard to
repeat: it just "happens" after you start optimizing, adding control
points, changing the lens settings, etc.

[reviving this thread] I don't see this problem but I'd like to hear
opinions as to whether this is a critical bug and should block the
0.8.0 release?

My experience with this problem on Windows Vista is that it is bad
enough to degrade the overalll user expereince from 0.7.0.  If it does
get released without fixing it, then there should be an option to use
the old preview as a default, so that the problem can be avoided.

+1. My TIFF files are on a network drive. Maybe on a local drive, and
with a larger default cache memory (75MB is kind of ridiculous
nowadays?) it is less of a problem.

The one thing that I'd change is that when the fast preview is closed,
so should the listeners that do the reload.

i am experiencing this problem on linux x64.  the opengl preview
window works very well until an image is added or removed from the
project.  if that happens, i've got to either close the preview window
and work without it, or restart hugin.  i've learned to work around
this, it definitely makes the user experience less enjoyable.  :)

I see this now and then on WinXP, even with much larger cache
settings.
I think it is a very annoying bug, and will lead new users to turn
away from hugin if they experience it in the first few times of use.
If it is possible to fix this within a limited timeframe (1 month or
so)  I would definitely hold up the release.

Thomas committed some cache related fixes three days ago (svn 3891).  
I have no idea if this helps, but I intend to do another release
candidate anyway to see where we are at - Since there have been a
lot of other recent changes.

I first couldn't decide here, but after an evening of
waiting-for-preview-to-close, saving panorama and reloading it, just to
be able to quickly identify some freak images in between the others and
deleting them I vote for fixing this bug as soon as possible, and if
needed waiting with the 0.8 release until it is fixed, as it is - in my
opinion - pretty simple to reproduce this bug (I can't imagine this
won't happen to anyone) by just removing an image while using the
preview or re-optimizing while the preview is closed.

If there might be a fix for this I'll try a recent trunk version by
tomorrow... :)

Hello,

Just posting my findings...

I believe I am seeing this problem under linux.  If I load a pano project and open the fast preview window.  There is a slight delay and then I can smoothly move the pano around as excepted.  If I then re-optimize the pano and try to drag around, the performace has dropped considerably.  I profiled  and found that vigra::resizeImageNoInterpolation() from resizeimage.hxx line 279 is using 88% of cpu time when this is happening. Profiling the good case shows the same function using 11%.  I am sure this would drop if I ran the program longer.


So...why is vigra::resizeImageNoInterpolation() getting called so often when dragging the pano  around after re-optimizing?  This is something to look into.  My free time has dropped to zero lately, so it may be a while before I can look at this futher.   But it may point someone in the right direction.

Best Regards,

- Gerry

Hi All,

I believe I have found the problem.  I have commit-ed a fix as of rev 3904.  The fast preview would realize it needed to regenerate textures, but wouldn't store their metadata properly.  So it kept regenerating again, and again....

I can't see any slowdown now. Only the crash (but It crashed also with
the svn 3888). I don't know if this crash is there for a long time or
not, because in fact today was the first day I've tried to reproduce
the slowdown which after a while causes crash.

I'm not sure, I'll take a look into bugtracker. Anyway, debugger gave
me this info:

hugin: /home/lukas/DEBUG/test-build/src/hugin-build/src/hugin_base/panodata/Panorama.cpp:1489:
virtual void HuginBase::Panorama::setSrcImage(unsigned int, const
HuginBase::SrcPanoImage&): Assertion `imgNr < state.images.size()'
failed.

So it may not be a crash but an assertion error.

I don't know what exactly triggers it, but it seems that when I open
the GL preview then remove some image, re-optimize it (It's exactly
the same process as what I needed for reproduce slowdown in GL
preview) then open the preview, select drag and play a bit it aborts.

Hi All,

I have checked in a fix for this as of Rev 3908.  I was able to trigger the error by:

1. loading project (this project only had 2 images)
   
2. opening gl preview
3. removing image
4. dragging image

Once I let go of the left mouse button, it would crash every time.

Best Regards,

- Gerry

Wow, that was fast. Thanks a lot, it would take me much more time to
find where the problem is, because I'm unfamiliar with the preview
code.

I have just tried to load and align a project that I had succesfully
processed using SVN3884.  I found that with SVN3906, I get an
"unhandled exception" after choosing "Align" from the assistant tab,
during the "Loading images..." stage.

Hello,

What platform are you using?

So understand, the steps to reproduce this problem are:

1. load a project .pto file
2. press the align button on the assistant tab.

Is this correct?

Rick is using Windows, but possibly this only appears with a zh_TW
locale.

Yes, I am using Vista.  I duplicated this issue in Traditional Chinese
and English, just to be sure it was not a wide character issue.

I loaded a project file from a project I previoulsy complete, 94
images enfused blended pano. Then press align button.  After the
"Levelling panorama" step, it starts "Loading Images" and crashes
about 10 seconds into that after loading a few images.  The Fast
Preview window never opens.

Let me know if you additional details.
