Re: [hugin-ptx] Re: Hugin 2010.1.0-svn4933 for download

[Carl von Einem]

Hi George,

2010.1.0-svn4933 definitely works on my PPC G5 when started from the
10.4.11 HD. I just tested with two projects, one from 2009-12-30, the
other one from 2009-08-29. Both open nicely, also using the fast preview
window. Oh, and it also works with projects (dating back to 2009-12-30
and 2009-09-01) just like yours: a single Equirectangular that needs to
be converted into a "little planet" Stereographic projection.

I suspect something is wrong with your pto file or maybe the input image
is corrupted. Does the .pto open in a text editor (e.g. TextWrangler,
just temporarily rename the extension from .pto to .txt)? Does the input
image open in an image editor (e.g. Photoshop, GraphicConverter)?

Only with recent builds.
2009.4 works fine.


This is probably related to the merging of the layout branch. There 
shouldn't be any '=' references in the first image at all.

Harry,

Would you expect this version to run on my old PPC G5 that is STILL
running 10.4.11?

I ask because I tried to open an existing project file with this
version of Hugin and it crashed almost immediately.
It was a simple project with a single Equirectangular that was getting
transformed into a Stereographic.

When I started a new project  and imported a single file and recreated
the transformation ... I must say the new fast preview is pretty
impressive ... based on the last five minutes experience! ... it
seemed to go OK ... it is rendering the output file while I am here
typing.

all the best

So it's crashing cause it's expecting an image before the first one.
To me it looks as a Hugin error.


In practice Hugin doesn't cope with any of these '=' references 
pointing to an image with a later number, so image 0 should never 
have any.  This sounds like a bug, do you only see this with the 
trunk?



The PTO file specification (which I never seem to be able to
find) allows for 'dummy' images which aren't really images, but
contain various settings which can then be reused using these '='
signs. Are there any dummy images present in the original .pto?


Never saw them before.


PTGui has these 'dummy' images that are not part of the project.  
Hugin has a different system where 'lens numbers' are implicit, so 
all 'i' image lines in the project refer to real photos.

I finally found some time to have another (better) look at this.
The image I uploaded is the general panini projection resulting from
selecting auto-crop in the stitcher tab.
I have tried this exercise again and although the crop boundaries are
shown as expected in the fast preview window, using the fast preview
crop or the stitcher tab auto-crop, the resulting stitch does not
comply with the crop boundaries.
Sorry I was a bit vague in the last post, I had tried to quickly catch

Here is the link to the uploaded image, it is about a mile long, hope

I made a simple one. Here's the rar: 
http://lemur.dreamhosters.com/hugin/ptMenderTest.rar
It contains my low pano and pto + ptstitcher scripts for a simple -90
pitch transform.
It also has an output, images + log.

Please test it out.

BTW in low-res Nona kicks PTmenders ass as it seems.

Well, I just rendered another test, and yes the outputs are the same
as Nona minus the vignetting correction.
I also saved the console output and it's a whooping 92mb log. Here's
the first 2k lines: http://pastebin.com/f503eff26

Tried it on a simple pitch transform (p-90) on a equirectangular image
and it's noticeably faster than Nona.
Though it only outputted a cropped square in the middle of the pano
instead of the whole thing (tried 2 versions of PTmender).

The script seems fine to me:

p f2 w11922 h5961 v360  n"TIFF c:NONE"
m g1 i0 f0 m2 p0.00784314

# output image lines

Sorry, i guess I just have to click one more time.

So from what I see, PTmender is not outputing correctly the entire
image? but what it outputs is accurate?
Not many people are using PTmender these days, so there isn't a lot of
testing on it.
But I want to fix the problems. So if we can find a good test case
that shows the bug, I'll take care of it.

Re: [hugin-ptx] Weird panomatic problem

[hdrpano]

Didn't know that.  I thought I read on some forum that panomatic was better
than autopano-sift-c for fisheye.  In the thread parallel to this one,
someone mentioned there was a bug that prevents autopano-sift-c from working
if you shoot landscape.  So that could explain why I always get zero points. 
Panomatic has worked beautifully for me up to these images, which are an
exception.


It is a known fact that Panomatic does not give good results for fisheye
lenses. The algoritms do not work correctly with fisheye lenses. Please
don't ask me why as I don't know. Sometimes you're lucky, sometimes you're
not like now. You should better stick to autopano-sift-c for (Full
frame)(circular) fisheye.

The problematic one is here: http://pastebin.com/f21e22535
I get that one when I load an already optimized project, add more
images and try to create new CPs. To be clear it's a temp pto.
If I save the project the first image is always ok.
All saved pto files look like: http://pastebin.com/f5338507d

Have no idea why it happens :?
Sometimes it works and the temp pto is like: http://pastebin.com/f31fd4213

Ok, that makes sense :) Thanks for the info!

So it's crashing cause it's expecting an image before the first one.
To me it looks as a Hugin error.

Never saw them before.

[hugin-ptx] Re: Hugin for Circular Fisheye

[Jeffrey Martin]

yes, Bruno is correct as usual. and it will work, i'm doing that right
now.

Wolfgang, you can certainly shoot with your 15mm handheld. Just
practice :)

if you want 3 shot panos, get a shaved nikkor or samyang. MUCH higher
resolution final panos, still in 3 shots.

Re: [hugin-ptx] Weird panomatic problem

[Harry van der Wolf]

It is a known fact that Panomatic does not give good results for fisheye
lenses. The algoritms do not work correctly with fisheye lenses. Please
don't ask me why as I don't know. Sometimes you're lucky, sometimes you're
not like now. You should better stick to autopano-sift-c for (Full
frame)(circular) fisheye.

Re: [hugin-ptx] Re: Hugin for Circular Fisheye

[Wolfgang Lin]

I did not get any ctrl point if I shot Circular in landscape. Berno
told me that it was because of the bug in autopano-sift-c had a
trouble to handle if the grog > 225 degree.  He told me to shoot using
portrait, then I should get ctrl point created!  I have not tried this
yet!

Jeff, the reason I use circular because for some situation I want to
shoot hand held with as less shot as I can. I also have a Canon 15mm
but I have to shoot with tripod and pano head with it.

[hugin-ptx] Re: APSC gives array out of bounds?

[Bart van Andel]

What does the original .pto look like? The '=' signs are used to refer
to images loaded earlier, e.g. 'v=0' means: 'take the v-value from
image 0'. The PTO file specification (which I never seem to be able to
find) allows for 'dummy' images which aren't really images, but
contain various settings which can then be reused using these '='
signs. Are there any dummy images present in the original .pto?

See [0] for an example (search for '-dummyimage')

(is Hugin actually using these dummy images? I'm not sure but I know
I've seen such lines somewhere...)

[hugin-ptx] Re: Hugin for Circular Fisheye

[Jeffrey Martin]

Hi Wolfgang,

slightly off topic, but why are you shooting panos with a 5d mk2 and
sigma fisheye? That's a terrible waste of your beautiful sensor. Get a
fullframe fisheye, or a samyang, or a tokina 10-17, or a shaved
nikkor. anything but a full circular fisheye

btw I use autopano-sift-c and circular fisheyes, and it generates lots
of ctrl points.
