Sliced Gigapixel Panorama Rendering: "Slicer"

One of the most annoying problems in gigapixel imaging is the fact that most image formats can't handle large files. Some proprietary (like Photoshop PSB) or rare (like VIPS) can do, but using them will inhibit continous workflow.

In an attempt to circumvent this restriction - and to make rendering faster, i have created a small helper application that will divide a large PTGui/Hugin project into smaller slices.
The rendered panorama slices can be easily post-processed or assembled in your favorite application.

You can download the current version here:

Update 2007/10/17: Microsoft Research has updated its HDMake tool. It can now assemble tiled source images. See this HDView blog entry for more information.

Compiling latest Hugin on OpenSuSE 10.3

Good news: with openSuSE 10.3, most dependent libraries for Hugin 0.7beta are in the correct state, so here's a quick roundup how to get and install:

  • Download latest sources:
    svn co hugin
    See for more information
  • Create bootstrap:
  • run "make", then "make install". You can speed up things with modern computers by using more than 2 CPUs, e.g. "make -j2" will use 2 CPUs.
  • At least for Gnome, Hugin will automatically create a start menu entry

What else is needed to run Hugin?

  • Mandatory: The panotools library (pano12):
    svn co libpano12
    See for more information
  • Optional: Autopano-SIFT (Tool for automatic creation of control points)
    Install instructions for the ignorant:
    - unpack autopano-sift-2.4.tar.gz
    - copy all files from the ../bin subdirectory to your harddisk (e.g. /usr/local/bin)
    - configure Hugin to use for control point creation
  • Optional: Enblend (Tool for seamless blending)
    I recommend still using Enblend Version 2.5 as V3 introduced GPU-based calculation which - at least on my computer - turned out to be tricky to compile.
