These executables are then added to the download section on SourceForge at http://sourceforge.net/projects/hugin/files/hugin/ A number of users have built recent snapshots and executables are likely to be announced within a few days of this tarball release. Watch http://groups.google.com/group/hugin-ptx for the announcements of binary releases. If you don't see a binary for your platform it has most likely not been produced yet. Consider stepping up to the task. Instructions at http://wiki.panotools.org/Development_of_Open_Source_tools#Supported_Platforms Announce your build on http://groups.google.com/group/hugin-ptx SPLASH SCREEN To promote artists using Hugin the project has adopted a user-contributed artwork to enrich the splash screen of this release.

Hugin has received a Python scripting interface and new lens calibration tool. A critical bug affecting a significant number of Mac users has been fixed and many general improvements have been made. _Lens Calibration Tool_ Lenses are designed to follow a perfect geometric model. For rectilinear lenses, a straight line in the depicted scene should be straight in the picture. This is not always the case: most lenses have an inherent deviation from the perfect model, resulting in imperfections such as pincushion or barrel distortion in rectilinear lenses. Adherence to the perfect geometric model is desirable for aesthetic purposes and indespensible to achieve proper alignment when stitching images. Hugin can calculate lens distortion parameters on the fly when optimizing a project, however this requires more control points and more computational effort than a project starting with a calibrated lens, and is prone to more errors. The new lens calibration tool calculates the distortion parameters of a lens based on an input image. The input image must contain straight lines, ideally many of them at different distances from the center of the lens, covering at least one quadrant of the image. The calculated parameters are valid for a given combination of focal distance, aperture (F-stop), and sensor. The values, saved into a lens profile, can be used in Hugin to achieve a better stitch, or on single images taken with this lens / settings combination to achieve a more aesthetically pleasing outcome. _Python Scripting Interface_ Hugin now exposes some of its data structure and functionalities through a Python module. To get started with scripting, start your Python interpreter and type: >>> import hsi >>> help (hsi) Standalone Python programs can access a panorama object with Hugin's functionality. It is possible to develop complete command line and even GUI tools based on this module. The Python Scripting Interface does not work on Mac OSX yet. _Python Plugin Interface_ Hugin can now run Python scripts inside the application. In an enabled Hugin binary, a new "Actions" menu gives access to system-wide plugins distributed with Hugin. Moreover, plugins can be written, modified, customized in the user's own directory. Currently there are only a few plugins available, but we expect the body of available plugins and functionality to grow organically as the interface is being made available to the general public. The Python Plugin Interface does not work on Mac OSX yet. _Other Improvements_ * PTBatcherGUI has matured to become the default processor for stitching projects. * ICC profiles saved in output. * Support for newer Olympus camera. * Improved auto cropping. * New mask type: exclude region from all images shot with the same lens * Copy&paste of masks in Mask Tab * Show extent of active masks and crop in Mask Editor * Fix for critical issue affecting stitching on Mac OS X Leopard. * Many more improvements and bug fixes. _Libraries and Build_ The Python interface introduces new dependencies: * SWIG >2.0 * Python UPGRADING Upgrading from previous versions of Hugin should be seamless. If you do have problems with old settings, these can be reset in the Preferences by clicking 'Load defaults'. It is strongly recommeded to set the default control point detector to Hugin's CPFind. It is the only control point generator endorsed by Hugin. Third-party generators may be compatible with the plug-in architecture. COMPILING Users compiling from source refer to the dependencies listed at http://wiki.panotools.org/Development_of_Open_Source_tools#Dependencies and the build processes listed at http://wiki.panotools.org/Development_of_Open_Source_tools#Build_your_Own_Test_Builds More information in the README and INSTALL_cmake files in the tarball. KNOWN ISSUES AND WORKAROUNDS Panosphere Overview window seperated from the content https://bugs.launchpad.net/hugin/+bug/726997 There is a known problem building Hugin with CMake 2.8.5rc2. Workaround: Upgrade to a newer CMake version. Mac OS X Users at Tiger and Lion: this version of Hugin contains an openMP enabled enblend and enfuse. These versions don't run on Tiger and currently not on Lion either. Please use the Tiger-compatible enblend and enfuse from the enblend-enfuse-4.0 folder in this dmg. You can specify alternative "external" enblend and enfuse from the Programs pane in the preferences after installing these special version by following the instructions in the README in the enblend-enfuse-4.0 folder. https://bugs.launchpad.net/hugin/+bug/814280 An updated list of issues deemed to be critical, including discussions and workarounds is in the issue tracker. https://bugs.launchpad.net/hugin/+bugs?search=Search&field.importance=Critical THANKS Thanks to all the contributors to this release and members of the hugin-ptx mailing list, too many to mention here.
