      Hugin-0.7.0 release notes

      Hugin is a panorama stitcher and more.

      Changes since 0.6.1

      Hugin has changed enormously in the two years since the 0.6.1
      release, hardly any part of the code has remained untouched. There
      have been many many bug-fixes, improvements to the interface and
      lots of new features - Here are just some of them:

      Online help

      Hugin now has comprehensive help documentation for the entire user
      interface, the manual now includes glossary items explaining many
      panorama stitching and related photography concepts.

      Languages

      New translations include Slovak, Korean, Bulgarian and Spanish. This
      means that hugin is now usable with a total of twenty languages.

      New Assistant panel

      Creating simple panoramas is much easier, hugin now starts showing
      an Assistant with a simple 1-2-3 approach for loading images,
      aligning and creating the final output.

      The Assistant will estimate lens and camera parameters, then pick a
      suitable output projection and size, advanced options are still
      available for manual adjustment.

      Photometric model

      Previous versions of hugin and panotools had basic support for
      correcting vignetting and exposure differences between photos.

      This has been completely overhauled, hugin now internally uses the
      EMoR model for representing exposure photometrically. This means
      that the camera response curve, vignetting, colour balance and
      exposure can now be optimised in much the same way as geometrical
      properties such as position and lens distortion.

      The result is that blending between photos is better than ever
      before.

      HDR

      Previously hugin supported High Dynamic Range imaging solely by
      allowing stitching of HDR floating-point TIFF photos - These images
      themselves had to be created in another tool.

      Now, thanks to the internal photometric model, hugin can now create
      HDR output from normal exposure bracketed photos. The photos don't
      have to be perfectly-aligned, they don't even need to be
      nearly-aligned or have consistent exposure differences - The hugin
      optimiser will sort all this stuff out, and the stitcher will create
      OpenEXR or TIFF HDR output files for later tonemapping or use as
      lightprobes.

      Exposure blending

      HDR and tonemapping isn't for everybody, enfuse introduced exposure
      blending to the world, and hugin supports aligning and fusing
      bracketed stacks of photos, perfectly, all as part of the stitching
      process.

      So now with hugin-0.7.0 and enblend-3.2 you can create realistic,
      photographic panoramas that have no over-exposed or under-exposed
      areas.

      Makefile stitching

      hugin-0.7.0 introduces a new stitching back-end: previously the
      various stitching tools were executed directly by the GUI, now all
      the commands required to generate the output are written to a
      Makefile which is then processed independently of hugin itself.

      Aside from easier debugging and customisation; this background
      stitching allows you to get on with creating a new project while
      waiting for the previous job to finish - Stitching can also be
      deferred or shifted to another machine, even 'headless' servers can
      now be used.

      Projections

      Hugin has always had the ability to save panoramas using simulated
      normal and fisheye lenses, or 360 degree cylindrical and spherical
      projections.

      Now a whole series of alternative cartographic mappings are
      available, of particular interest are the 'conformal' stereographic
      and Mercator projections which can be used to show extremely large
      angles of view with no local distortion.

      Project templates

      Hugin project files can now be used as templates for new panorama
      projects. This is useful if you take a lot of panoramas with exactly
      the same camera positions.

      Other improvements

      There's a whole lot of other new stuff in this release: numbering in
      the control-point editor, straight-line control-points, numeric
      transform, clicking to rotate the preview, a straighten button,
      cropping of the output and probably more.

      Command-line tools

      This release provides new command-line tools:

      * align_image_stack: align a nearly-aligned stack of photos
      * pto2mk: create a stitching Makefile from a pto project
      * vig_optimise: optimise photometric parameters
      * tca_correct: calculate lens chromatic aberration
      * hugin_hdrmerge: assemble a bracketed stack to HDR
      * matchpoint: classify control point features

      Control point generators

      Hugin doesn't yet ship with a 'Patent Free' control point generator.
      So you either need to pick control points manually - Not as
      difficult as it sounds - or install and configure one of the
      following control-point generators as 'plug-ins', in no particular
      order:

      * autopano-sift-C
      * panomatic
      * Autopano-SIFT
      * Autopano freeware version

      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'.

      See the the README and INSTALL_cmake files for more information.

      Thanks to all the contributors to this release and members of the
      ptx mailing list, too many to mention here.

            Indeed. It appears I've been "out on a limb",
            since I'm using Hugin under Linux, and enjoying it.

            I didn't know so many (other) people didn't know about it.

            The performance of Hugin/Enfuse greatly exceeds their
            cost :-)
