In fact, "Family" was probably the only image that I could turn easily into
a 360 pano, as my other stills are not meant to be seen from another point
of view. I wanted to do the "Wet bird", for instance, but I realised that I
had to create other buildings, add more cars (and create headlights for the
cars...) etc. And yes, a good 360 pano should be created on purpose from the
very start. It's quite an interesting challenge.

I'm not sure if you mean the "Family" image itself or just the QTVR... I may
write a "making of" in the future, but in a nutshell it's just a bunch of
pipes created with my "MadPipe" macro with additional props (particularly
some from http://www.baument.com) and Poser characters thrown in.
If you mean how to turn the POV-Ray scene into a QTVR file, here's how to do
it:
- download Panocube http://www.panoshow.com/panocube.htm and the Panotools
suite http://www.path.unimelb.edu.au/~dersch
- create a directory so that there is no space in the path name, such as
c:\panorama (but NOT c:\program files\panorama)
- unzip the Panocube file and put Ptstitcher.exe and Pano12.dll in this
directory
- drag and drop Ptstitcher.exe on Panocube.exe : this tells Panocube where
Ptstitcher is and needs to be done only once
- to create the QTVR, drag and drop the image file on Panocube.exe, and
Other conversion options (size, etc.) can be edited in the script.txt file.
There's also a commercial version of Panocube with more options.

Why not? To get a panorama like this the image is already 3000*1500. I'd
need something like 12000*6000...
It's much more work though, because I'll need much higher radiosity for some
of the parts otherwise the Poser folks will just look like they have some
skin disease. I had this problem with the still version and I had to go
through the painstaking process of using masks to insert high radiosity
versions of the characters into the low rad version of the rest of the
scene. Well if I can find the time I'll have a look.

Oh, I see. I thought this is a cube map and you had to render six sides...

It's the best 360 image I've ever seen. Most 360 images are photos and
always have artifacts or seams, but not here. Very impressive.

being spherical, not cylindrical. (At least, I *think* the number is
64800, calculation could be wrong)

No. Degrees (and radians) are used only to measure 2-dimensional angles.
You can't measure spatial angles (I think that the mathematical term
is "solid angle") with degrees.
Solid angles are measured in steradians. The solid angle subtended by
a surface is defined as the surface area of a unit sphere covered by
the surface's projection onto the sphere.
The solid angle corresponding to all of space being subtended
is 4*pi steradians.

Hi Gilles,
Tried it but when dropping the image on the exe, it says "Not
equirectangular input" ?? (For info, my picture size is 400x400 (dividable
by 4) and the camera was spherical camera angle=360d -HORIZONTAL - what
about the vertical ?)
Thanks,

Though astronomers and astrophotographers like to talk about "squared
degrees"...
