Hello,

as there is actual coding of new software going on, maybe one can iron out a deficiency in the Hugin lens model. At least lay the groundwork for it.

The Brown-Conrady model parameters are sound, but the intersection with the abc-Hugin parameter set contains only one (1) non-trivial distortion parameter.

I suggest to add further Brown-Conrady parameters to the software code you are currently writing. Now.

Best regards

Klaus

Monkey, I much appreciate your software.
I like it because I like big panoramas ... and the speedup is welcome.

For big panoramas there's another issue: Geometrical optimization is slow.
I developed a fork for the libpano library that I called fastPTOptimizer.
For large panoramas the speedup factor for optimization can be 100 or more.

I integrated both your multiblend and my fastPTOptimizer into a "development version" of Hugin. Multiblend is now the default enblend-like program (in the GUI is still written "enblend" but you can see that multiblend is used by choosing Preferences / Programs). Only the CMakeLists.txt files are not updated so that Multiblend is automatically integrated
because I'm not yet so familiar with creating files for CMake.

My version of Hugin is here:

    Has anyone out there tried either the x64 or x86 versions of
    Multiblend 2.0 on Windows XP or Windows Vista? Someone's reporting
    vcredist problems and I'm not sure if it's because I built using
    the latest platform toolset.

            It seems Groups won't let me post the quasi-essay I had
            written, complete with images, so the link above will have
            to suffice.

            Here's Multiblend 2.0, faster, better, more... blendy. I'm
            calling it a Release Candidate because there's only so
            much testing I can stand to do, and I've hit a dead-end
            with features, so I thought I'd put it out there for
            people to try. I expect some bugs to be found pretty
            quickly, which I'll hopefully fix pretty quickly.

            It's released under GPLv3.
