RORO01  The tip provided below by PLANET is tedious and not necessary any more.

1. Create a folder and name it Hugin in /Library/Application Support

2. Create a folder and name it Autopano inside the above folder

3. Copy the file "Autopano-SIFT-C 2.5.huginAutoCP" (provided in the download) into that

Autopano folder

4. Launch the application and go to Preferences>Autopano and ...

A. Under "Select Autopano" choose "Autopano-SIFT (by S. Nowozin)"

B. Ensure the checkbox in front of "Use alternative Autopano-SIFT program" is NOT ticked

Autopano-SIFT is now set up - enjoy using Hugin!!!

PLANET  This is the best piece of open source software I've ever used altough the provided "put autopano sift to hugin" script always failed and the developers made a big secret how to use autopano sift with Hugin.

After using the "sift helper" programm for one year I found a workaround:

How to set up autopano sift with HUGIN:

1. Right click on Hugin.app : show folder content.

2. Navigate to the folder Hugin/contents/resources/

3. in the folder "resources" create a new folder: autopano-sift

4. the following files must be copied into the new "autopano-sift" folder:

- autopano

- autopano-complete-mac.sh

- autopano-complete.old.sh

- autopano-complete.sh

- autopano-win32

- autopano.exe

- autopanog

- generatekeys

- generatekeys-sd

- generatekeys-sd.exe

- ICSharpCode.SharpZipLib.dll

- libsift.dll

- showone

- showtwo

5. now autopano sift works fine.

One of the best kept secrets solved.

RORO01  Many, Many Thanks!!!

I'm very grateful to the developers of this wonderful application. It is a must have if you like traveling and have a digital camera. Also, many thanks for creating a perfect Help documentation.

ISGOED  Typical OpenSource: 0.7b1. Too confusing and not maclike at all. Crashes when aligning or runs forever  
(Version 0.7RC6)

THREEDEE912  This software makes great panoramas, but it's a bit confusing to setup use, even with the new "Panorama Helper" thing, and the UI is also a bit confusing. The price can't be beat, however.  
(Version 0.7RC5+)

RORO01  Panorama preview window - Version: 0.6.1

The buttons "show all images", "show none of the images" and the numbered buttons are not working. iMac Intel 10.4.11  
(Version 0.7b4)

TOMIS  The Download links to the 0.7b4 source code, you will need the Apple developer tools to compile it.

The last MacOS X binary (ie, built application) was version 0.7b1, you can download it at http://downloads.sourceforge.net/hugin/HuginOSX-v07b1.zip  
(Version 0.7b4)

DRAW  Something for freaky software developers. I found not one application to start in the all the files.

That is windows like....

RORO01  A VERY USEFUL APPLICATION BUT CAN'T CALL AUTOPANO-SIFT.

I have installed mono framework and autopano-sift onto my Intel iMac (running OS 10.4.8) and HuginOSX works perfectly. I have chosen "use alternative autopano-sift programme" from the preferences of Hugin OSX and directed it to autopano-sift-2.4/bin/autopano-complete.sh.

When I click on "create ctrl points" in Hugin I get a panel headed "running autopano" which says "please wait while autopano searches control points ..." After a short while I then get an error message headed "autopano failure -Could not open autopano_results_tempfile.pto for reading. This is an indicator that the autopano call failed, or wrong command line parameter have been used."

I ran the script autopano-complete.sh independently via ScriptGUI and it returned the result:

fork: Resource temporarily unavailable

csh: No more processes.

I have been trying this for the last month to no avail and have emailed the autopano-sift developer but haven't received a reply.
