The changes were intended to synchronize PTBatcherGUI and PTBatcher.
Both are using the same queue. But when PTBatcherGUI was running and a
project was added or removed with command line (ptbatcher),
PTBatcherGUI doesn't reflect the changes in the running instance. You
had to restart PTBatcherGUI to see the changes. Currently I try to
reread the queue when the file was changed.

These things are running without problems on my machine with Vista. I
see the same implementation make troubles on Linux.
Are there user (especially on linux) which are using PTBatcherGUI to
monitor the queue and manage the queue more likely with command line
ptbatcher?

The simplest solution would be to comment out the synchronisation
part, which probably causes the troubles. So we could release 0.8 with
PTBatcher. The fix of the problem would be a matter for the next
version.

Ha! You're right. The program should, but doesn't read the dimensions
of the images, and adjust the rectangles from that. Did you read the
comment at the top, it says that it works for my project and probably
won't for yours. :-)  Sorry.

If you exchange all the two's and threes where there are lots
of twos and threes near eachother in one big printf, it will work for
you
(but no longer for the project I made this for initially)

ok, the trunk now runs without crashing, though it doesn't pick up 
the content of the queue file when it starts and soon enough 
locks up with an error like this:

   Xlib: unexpected async reply (sequence 0x2839)!

Thomas, how close do you think this is to being releasable?

I don't really understand how it is supposed to work, there is a 
whole facility for saving and loading queue files, but why would 
anyone ever want more than one queue per user?  Surely that is the 
whole point?

i just tried your ptomapper.  it read my pto file fine and the
postscript file was created successfully, however there is an issue
with the image map.  the rectangles representing each image are
rotated 90 degrees.  i shot the images in potrait mode, they are shown
in landscape in the postscript file.

i can initially use a tool like this to check my overlap in photos,
very useful to fine tune the angles at which i need to shoot for a
given lens/focal length.

[Joe Templeman]

Polar panoramas generally do have this effect. A lot of planets you see will
in fact be stereographic projections. This is a completely different
distortion and MUCH better in most cases. You can do this again in hugin by
starting a new project, importing your equirectangular image, setting the
pitch to 90 and the projection to stereographic. This will generally create
a planet with much nicer proportions.

I posted a tutorial on flickr ages ago (its an old version of hugin) but it
should still hold true.

Hope this helps.

[hugin-ptx] 360x180 planet panos and distortion

[slaterson]

i recently started shooting full 360x180 panos.  i was surprised at
how quickly i was able to get good results when making these, i have
shot only five or six sets of photos in a couple locations so far and
i've gotten three decent planet panos out of it.  i would like to make
great panos, though. :)

the first thing i have noticed is distortion.  when comparing my panos
to others online, mine seem to be much more distorted.  i'm shooting
with a 28mm focal length, and end up with 90 images + 1 nadir and 1
zenith.  after stitching these together, i open the resulting image in
gimp and resize to a square image (6000 x 6000 for example) and then
apply a polar distortion.  the result is a planet, but distortion is
visible.  any people in the shot look short and wide.  the people in
the photos are about 5-10 feet from the camera, it doesn't seem to
matter if they are closer or further away.

is this a result of the way i am taking photos or how i am stitching
and distorting the pano?

[hugin-ptx] Re: Stereographic video

[Dale Beams]

Immersive video, not there yet.

These are great examples of video panoramas.  On a side note to be truely 
immersive it would need:

1. A spherical room or VR goggles.  As impressive as this is (and it is 
impressive) one is still limited to a flat view on a flat screen with a cropped 
view 4:3(?).  My peripheral vision is about 180 and it's out of my peripheral 
vision I pick up a lot of information.  The ability to move one's head around 
while keeping the peripheral vision view is important.
2. Truely sterographic (ie, 3D).  True sterographic is filmed with two cameras, 
about 3-4 inches apart allowing a green/red with 3D or sterographic glasses.  
For films this means processing two sets of almost identical film.  With low 
end video equipment, the cost would be on the processing power of the 
individual.
3. Interactive.  The ability to click within the panorama and get audio 
feedback.  Ie., seeing and individual with a clickable icon/box and clicking on 
them to hear the audio from them.  This would require more effort, as it would 
require a "reporting" team to get audo interaction between two people or about 
objects within the panorama.  This is great for live events or museams.
4. "Live".  This i see as almost impossible, but not quite.  Stitching six 
different "live" video feeds with small delays would make it truly a immersive 
experience.  The videographer could be fitted with a earpiece and  then under 
the control of a web viewer (one at a time) could be directed to interview 
individuals or inspect objects.  This would be truely live television.
5. The implications of "live" panoramas are enourmous.  For example, a team of 
indivudals with various "light" seeing cameras and and motion detection 
technologoy (all of which are availabe to us - in linux no less :) ) could walk 
through hostile situations with "an extra set of eyes" watching what they are 
watching as a margin of saftey allowing the "human" factor to stay involved.  
This would take field agents out of the field, put them behind the saftey of a 
screen or panoramic room.

I have to agree.  The light on the singer does not change when switching

from evening to night.

Once each frame is stitched to a pano it can be remapped easily.

I was considering a windowless room lid by artificial incadescent light. 
It is surprising that obviously noone has ever really tried this so far. 
But maybe for most panoramic applications, the accuracy of the 
vignetting calibration is not that important, as enblend & Co. correct 
for the seams nicely. Still, for me this is not an option, so I will try 
to find a suitable room now. The tripod-head is also selected and should 
arrive a bit later ;-)

CU Lars.

[hugin-ptx] hugin installer for Windows Vista/XP

[Ad Huikeshoven]

A fresh hugin installer has been built for Windows Vista/XP based on SVN
revision 3797. Known issues include but are not limited to PTBatcherGUI
hanging and the new fast preview window might crash your system.

Since the previous installer was pasted a week ago, 13 patches have been
applied. These include multiple translations updates by Bruno Postle and
others. prokoudine and tmodes issue several patches related to PTBatcher -
so maybe one day the known feature of PTBatcherGUI hanging will be resolved.
ippei, harryvanderwolf and blimbo also issued patches.

Please find the installer here: hugin installer for Windows
Vista
.
