helmut,
will it be possible to rotate object and pano separately?
or just the object while active, perhaps?
i.e.: i can much easier think of applications where one might
want to load an object then rotate it and unload it so that the
background pano stays at a certain fixed point during the time
the object is active.
also, the rendering of object movies seems to take a lot longer than that of
panoramas of the same size, or larger. is that normal? i use single rows
with 36 images usually . . .

Subject: imove .pan edit how?
Hello Ralph.
I made a little program that converts an Equirectangular Panorama to the
.PAN format.
Helmut helped me with it a little time ago.
Is just like the MakePan program from Helmut but for Windows, I called it
"MakePan for Windows".
You can open BMP, JPEG and TIF files with it and control the JPEG
Compression of the final PAN file.
I work usually with uncompressed BMP files in true colour and then when
ready use the converter.
If you just rename your JPEG files to the PAN extension, you do not include
the header information which has the total size of the file needed for the
show percentange when downloading.
My program only outputs JPEG Pan files.
If you want it ( or anyone else on the list ) just let me know. I can E-Mail
it to you.
Is 936 KB.

Subject: Digital camera set to wide
I have a 50mm lens camera which has produced some excellent panorama
pics via PanoTools and PTGui.
However, a colleague has sent me some photos he took with a digital
camera with the zoom set to fully-zoomed out. He says the manual tells
him that this is equivalent to a 55mm lens. The images have a slight
wide-angle distortion and try as I might I can not get PTGui to produce
a sensible panorama - it usually has the first image as a wedge and the
other images placed on top of one another (I think!) very small in the
centre of the 'panorama'. I set the lens type to rectilinear in PTGui
as it is not a full frame fisheye, but I suspect the distortion of the
images is getting PanoTools confused. I have tried other lens types in
PTGui but nothing helps.
Can anyone suggest how to process these pics to get a panorama?
Thanks in anticipation

Subject: Stand-alone 3D-accelerated viewer?
Is there a stand-alone EXE viewer on Windows that uses 3D hardware to
accelerate panorama viewing?
I'm thinking of something like a VRML viewer but stand-alone, something
you double click, without needing a browser and HTML file.
A long while ago I tried the Dagoth Moor Zoological Gardens demo from
the GeFORCE people, and in their wireframe mode you could tell that the
"world background" wasn't a six-sided cube: it was hundreds of triangles
tessellated in a near-sphere around you. Wouldn't this give better rez
and less distortion than the VRML cube background? Is there another 3D
viewer system that uses this trick?
Obviously what I'm looking for is a pano viewer where "navigation" --
panning and tilting to view the pano -- is as fast and natural to use as
Half-Life or Quake. Thanks.

Are you sure of that ? "standard" zooms on compacts or digicams are more
often 35 to 105 mm equivalent, perhaps you should try 35 mm (50° hfov). But
optimizer should probably take care of that...
Another problem that might happen: your friend rotate in the other way, and
you should negate initial yaw angles accordingly.

Most VRML-viewers don't need a HTML-file, but can directly read
'wrl'-worlds. Other than that you could use Quicktime VR
which (AFAIK) uses hardware acceleration.

No, it would not give less distortions, but would require
more time to render, and would give worse image quality
since there are more edges, which are always problematic.

VRML can do that and probably almost any
other VR-modeling system. You have to set up
the triangulized grid background, and texture
map the panorama onto the triangles.
You could also force PTViewer to act like that using
multiple instances of PTZoom.

Some of these games (I guess it is Quake but I'm not sure)
can be used as Panorama viewers in that they provide
means to construct your own world with cubic background etc.

Subject: memory bloating with ptstitcher
Attempting to figure out why ptstitcher continually crashes in the last
phase of creating a panorama, I carefully watched the memory requirements on
my mac. I was creating a 14350 x 2708 pixel image from 13 x 2000 x 3000
pixel images. Everything went fine until ptstitcher tried to insert the
final tiff, at which point the memory requirement suddenly ballooned to 760
Mb, hit the ceiling, and the app crashed. Two hours of rendering wasted!
According to the readme of version 2.5
> Memory Requirements:

according to this equation the RAM required is about 14350 x 2708 x 4 + 1
bytes, which works out to 156 Mb. This is exactly the size of the
almost-rendered pano file, but the app seems to be looking for at least
*four times* this at the end of the process.

Oh great.... just when I decided to cut vr objects out of a rainforest
project I'll be working on because your couldn't zoom. It'll be a lot of

The speed's pretty good considering the extra interpolation quality. Very

Johnny
Somewhere in the package (within the goodies folder) you downloaded there is
a .tif named: 'flags'
You have to manually cut and past (hopefully in a layer other than the
canvas or in a copy) those ugly (sorry prof:-) arrowed flags and than
1) make the plug-in read' em
2) run the optimizer
Or you may drow your own arrowes with the Photoshop line tool and than write
down x/y values by hand
And even use PTPiker to mark the feature.
There aren't many advises to follow in order to determine haw to set control
points but Two:
1) Choose something that shows a good contrast difference (an angle of a
door in a building, for one) But it should be nice if - a day - Prof Dersch
implemented the chroma difference also: as in several motion tracking
system.
2) Do not set any of them close to the border of the seam, neither
orizontally nor vertically. Especially with regards of vertical onces vhere
the optimizer routines can't often cope With the very high imagines
curvature.
Never-the-less
There are Exellent tutorials around the web: look for those of Philo and ben

Shockwave 3D has the ability to be accellerated by DirectX OpenGL or via

I am suprised that Netscape performes slightly better without the java
plugin/shared library. This isn't the latest available, and perhapse
Sun's would perform better, but I didn't want to spend another 15
minutes trying. Later I may install NS6 and post it's results.
Now that I've played with the appletviewer and see this in comparison
with other people's numbers I know what I was missing =).

Subject: Installing PanoTools on Linux, libpano12.so issues - Update
Hans-Dieter Kluge emailed me with some suggestions, and by following
them I was able to use Sun's Java port of jdk1.3.1 to Linux.
Basically I needed to use the library switch:
- -Djava.library.path=/usr/lib when calling their java interpreter, since
my libpano12.so is installed in (copied to) /usr/lib.
E.g.: java -Djava.library.path=/usr/lib -mx64m -jar ptpicker.jar
This seemed to run just as well as blackdown's port, which must look in
/usr/lib by default rather than /lib or where ever Sun's default
location is.
Setting the environment variables make things more convenient, but I
found only the library switch to be necessary.
E.g. (bash/sh style):
export JAVA_HOME=/usr/java/jdk1.3.1/jre
export PATH=$PATH:/usr/java/jdk1.3.1/jre/bin

John,
I don't know what has happened here. Are you sure that
the app really requested 760MB, ie did you check
the corresponding 'About this Macintosh' dialog?
Could you tell what output options you were using, and
at exactly what stage the app crashed (most recent
progress message + failure message).
There may be many other reasons for a failure
eg disk space. In your example at least 14 full
sized panoramas need to fit on disk, ie 2.1 GByte
space is required. The alpha channel does not
need any extra space, as you suspected in another
mail, since it is stored in the fourth pixel, and we use
4Bytes per pixel anyway.

Subject: Parameter settings in PTStitcher-Script
Hi,
perhaps someone of you could do me a favour:
Due to the results (not satisfying because I'm using not a common lens) I
got with PTStitcher, I tried to vary the parameter settings in the
PTStitcher (the optional lens correction settings a, b and c and the HFOV
that I do not exactly know for my lens).
Could someone please explain me the effects these settings have? What
exactly is happening to the image when I increase/decrease this values or
change the sign?
What is the mathematical relationship between a, b and c?
Thanks for your assistance,
best regards
Guido Kowollik

I've contacted him again, and he's rechecked the details. Here are the
'correct' details!
The camera is a Kodak DC280. The manual says it is a 30mm lens
equivalent when fully zoomed out. He has now measured the hfov as being
just over 60 degrees. I haven't yet had the chance to try 60 degrees in
PTGui but I did try a large range of angles and they appeared to make
very little difference.
Is this lens type rectilinear, even though there is quite a lot of
pronounced 'bowing' of verticals? I'm not an experienced photographer,
but I was a little surprised to see this 'bowing' because the only wide
angle lens I have encountered before (which was on a fixed-focus
camera) had perfectly straight verticals and horizontals. I am right in
assuming that the optimiser should be able to straighten these images
out automatically without any manual pre-processing?

I've checked that. All five images are arranged correctly from left to
right. The optimiser does however generate some weird figures for the
yaw - e.g. with central image set to 0 degrees the fifth image is
generated as -172 degrees!

This value seems better, but as you mentioned it won't probably make a
difference after optimisation.

Yes, this bowing will be corrected if you provide enough control points and
you optimize for (at least) b parameter.

Partial panoramas are actually more difficult to optimize than 360° ones,
because there is no absolute reference for hfov. Try a step by step
optimisation: First optimize for angles, without optimizing for hfov or
a,b,c correction (let a=b=c=0). Then add optimisation for hfov, then add
optimisation for b (set initial value to -0.03).
If this doesn't work, send me your scripts before and after optimisation,
I'll check them !

I'm running with roughly the same software setup as Jacob and can
confirm the extremely slow framerates of the combinations mention
above.
I got fed up with NS 4.7 and upgraded to mozilla 0.9.2 and sun's 1.3.1
J2RE earlier today. All that I can say is: "WOW!" Is this how PTViewer
is supposed to look and feel? I couldn't understand what all the fuss
about "ballistics" was all about earlier in the week, as I have never
ran PTViewer as a standalone program.
NS4 didn't allow me to even get a feel of PTViewer's performance.
Linux users: you owe it to yourselves to upgrade browsers.
sorry i don't have concrete numbers for the frame rate but it is 10x
faster than it used to be.
cheers,
Kobus.

Yes, that's where I was watching the process.

here is the p-line from the script
p f1 w14350 h2708 v360 u10 n"PSD_mask" -buf
(the same thing appears to happen with PSD_nomask but I will run it again to
be sure)
The last progress message was 'Inserting Tiff 0' or something very similar.
The app had definitely (1) converted all the image files and created the
alpha masks, and was on the *last* image insertion when the problem
happened.

There was at least 4Gb available on the disk before I started the process so
I doubt this was the problem, and like I say the app failed with an 'out of
memory' message, and I watched the 'about this Mac' memory bar shoot up to
760 Mb on this last phase of the operation.
I will try to recreate the problem and give you more details.
There is also another experiment I can try which may throw some light on
this.
