There is also a Facebook group lobbying against this
http://www.facebook.com/group.php?gid=105741059455603
    It's rather worrying when organizations like the BBC are involved
and lobbying for control of orphan works.  Those of us who have
contributed editorial features to BBC Worldwide have reason for
concern that despite clearly stated T and C's limiting use there may
well be the possibility of them "discovering" material on file that
should have been deleted and seeking to exploit that.  Having had to
go through the process of a novation agreement when one of the BBC WW
titles was sold to another publisher I have suspicions that "Aunty"
isn't the kind old dear that we are led to believe!

Hi,

what catched my eyes in the posted link was not the 3D stuff (I'm still
not convinced that it is just fake - Google has 3D data from the laser
scanners) but the interactive way to view user photos (upper left
corner). There, a Photosynth-like transition between images is
implemented. I tried it out for photos around the empire state building
- - quite impressive.

Aren't we a bit too paranoid today? Why should it be a fake/joke? It apparently
works (I
have no 3D glasses to verify it, but it looks like other 3D images), all over
the world,
so it's not a mockup from Sidney alone. And if it works like that, about as bad
as normal
GSV,  why should it be a joke? If you were tricked to go to that URL to view 3D
GSV, and
there was none - that would've been an Aprils fools joke?
I saw another GSV message though, where it was said that Google would test live
video GSV
at a certain location at a given time, and that one is obviously a joke, where
they can
"measure" how many were tricked ;)

For a April 1 joke it is done very well but not for a real experiment.

With a red/cyan anaglyph viewer I noticed that the stereo separation, which
should be applied to far objects, was set to close by objects resulting in a
severe stereo window violation (I know this because I made the same huge
mistake when I started making 3D panos).

I m pretty sure that this is a plain pano that is manipulated with software
to show an artificial 3D effect, there are to many things not right in the
pano, you can see it when you rotate the pano with a viewer on.
There is another thing that makes it almost for sure a fake 3D pano, for
shooting 3D panos in a dynamic environment like a streetview you must have
at least 24 (more is better) static mounted cameras and then use the
parallax between the images to create the left and right eye panos needed
for the creation of an anagyph 3D pano.

BTW, making a 3D pano can be done even with a single camera and a fisheye
lens but for this you need a "frozen" scene.  On the website of NodalNinja I
posted a tutorial how to do this.

You want to be able to create your tours quickly and have many options
open... that means:

http://flashpanoramas.com/player (FPP) combined with
http://flashificator.com (FFC)

With that combo, you can drag and drop your hotspots into the panorama in
real time, move the items in real time into correct positions, link things,
add maps/floorplans, etc. etc. etc. with a few clicks of the mouse.

If you want an offline presentation, it takes a single click in the
interface to create a standalone flash projector with your entire project.

Works for Macs and PC's alike.

The best panorama format to use in FPP is 6 seperate cubefaces, but it does
also support equirectangular, stripe, mov and cylindrical (even though the
cylindrical projection is not what it "should" be).

If you choose FPP without FFC, you will have to dig into xml coding, since
FFC is the front end GUI for FPP.

KRP is another great panorama viewer, but it is 99% based on hand coding,
and that can be too big a bite for many (me absolutely included).

Hope this helps.

(the "father" of Flashificator)

Before the rumors start floating around I thought I should make mention of an
important upgrade we are performing on our servers.

We are combining 2 servers (website and store) into one. The newer dedicated
sever is much bigger and faster (100Mps) with higher performing CPU
(QuadCore 8GB Ram).
During this time our website and NN forum will see occasional outages
(emails are working). The e-store (store.nodalninja.com) and all links to it
however will not be affected until we are ready to migrate it a few weeks
down the road.
Thank you for your patience.

I didn't use compatibility setting. I use Deval stand alone for local
viewing anyway, but unfortunately this wasn't possible for web pages
(since I didn't want to have Deval process all MOVs).

I already had a headache before I read your message and started thinking about
it, so please forgive me if I say something stupid.

The stereo separation is basically the same thing as parallax "error" between
your two eyes, right? And we all know that the closer objects are to the lens,
the more parallax errors are an issue. Parallax issues are far less of a problem
with far away objects (ie: mountain views are easy to stitch).

So... shouldn't far away objects have little separation in stereo panoramas?
Just like Google does it now?

Ofcourse this is on the assumption that you are focussing at infinity; if you
focus closer than infinity you may get stereo-separation again on distant
objects because your eyes are slightly crosseyed. Objects further away than the
focuspoint will separate in the other direction than objects nearer than the
focuspoint. Or am I mistaken?

Ouch, headache...

PS: I am still convinced there is no such thing as a fully "correct" 360x180
spherical stereo panorama. I guess I may have to wait until Plymouth to be
really convinced.

Did you expect a 64 bit program? It needs to plug into firefox f.e.
which isn't available as 64 bit either...

no that is right

Stereo games drivers have an autoconvergence feature so that the bulk of the
scene is always behind the "window" -- ie. the apparent plane of the screen --
but not too far behind.  This would be a handy feature for stereo pano viewers
too but it would need a depth map to work I think. You can generate a depth map
from the parallax information in a stereo view but I dont know how well depth
map generation can be done in real time. If you have a depth map anyway like
StreetView would have if they started shooting stereo panos then it would not be
an issue.

  There is the concept of the depth budget of stereo displays too viz. the range
of reproducible depth impression of a particular display technology. Projection
3d has a large depth budget, lenticular and autostereoscopic displays generally
small. Subject depth must be matched to the depth budget of the targeted display
otherwise the depth impression will be too small or large. If too small things
look flat, if too large your brain wont resolve the parallax. In real world
situations when we look at something close we ignore the image doubling in the
background but not so much with displays.

With stereo panoramas you will often have a difficult situation for depth
budgets. The nearest thing to the camera will often be 2m away at ground level
around the camera, and the furthest infinity. Which is a big range if the main
interest is more than a few meters away. The screen depth will have to placed at
2m which means the depth budget for the more distant background is meagre. So
there is a big argument for pole panoramas for hyperstereoscopic outdooor
scenes.
