[OSX] 20120101 New Hugin bundle 2011.5.0.5720:dcea30ca8a02 including new experimental multiblend

[Harry van der Wolf]

Hi mac users,

Happy new year to you all.

I built a new Hugin bundle including the new multiblend 0.1a. (1,2,3) from David Horman. You might already have read about it.

It's not completely integrated in the bundle yet, so how do you use it:
- In Preferences, goto programs -> use other enblend
- browse to the HuginTools folder (next to your Hugin.app and PTBatcherGui.app) and select multiblend
- If you set advanced enblend options leave them out temporarily (experiment later).

Notes:
- multiblend can only run on Intel machines (universal i386/x86_64 binary) !!!
- multiblend can only create tiffs. If you have jpeg as default (like I have), make sure to specify the correct output format.
- multiblend uses a lot of memory, especially with larger panos (logical off course).
- The error mentioned in (3) has already been corrected.


Please experiment and report your findings here in the hugin google group. This means both errors in multiblend itself as well as in my configuration.
I'm not sure yet whether multiblend errors should come in the hugin launchpad.


Tiger and Lion users: Use the Tiger enblend from the enblend-enfuse-4.0 folder inside the .dmg.
(This is the normal reminder if you use enblend. Does not relate to multiblend)

Here’s my results. I just went out and shot these, and then put them through this edition of hugin, set to multiblend according to your instructions. http://www.flickr.com/photos/iantindale/archives/date-posted/2012/01/02/

Looks fine, apart from the missing wrap. We'll need that for 360X180.

Thanks for testing. Nice images apart from the very obvious seam at 360 (due to multiblend's unability to do that yet).
Did you do a speed comparison between enblend and multiblend?

My experiences so far are that multiblend is around 3-5 times faster.

I didn’t do a speed comparison, it all went by too fast. It’s on a hackintosh i7-2700K with 16GB ram, running Lion, and it couldn’t match the control points properly on all of the shots until I took over and did that bit manually (which is fair enough — it’s only the horizon that contains anything useful and much of that is repetitive intervals of lights). Once I’d manually matched up a few, it matched the rest easily, and then for the stitching, it just zipped by almost immediately. 

I say that it’s a six shot pitch variation, but it’s actually seven — six shots, 60° apart around, and angled up or down at: -15°; +20°, +20°, -15°; +20°, +20°, then back at position zero I took another at +50° to get the zenith (and also to compensate for the drop in daylighting by the time I’d done the circuit). I should have shot a nadir but that’s a] very difficult without mostly shooting the tripod, and b] on the way to being unnecessary at night as I can almost get away with filling the ground in with darkness. For some reason I did it wrong, as I had actually intended to do -20°, +15°; +15°; -20°, +15°; +15°; then a repeat at zero position at +50° for the zenith. That would have given me a touch more ground than I ended up with. Oh well.
