Pretty damn cool

That is very cool indeed.


I thought about this some more. It doesn't have anything to do
with 3D--you can only spin the image in one axis.
I'll bet this is 2D frame-to-frame pixel morphing.
The user takes 4-8 still photos in a regular axis rotation.
Then something vaguely like Xmorph interpolates a bunch
of new frames between the original image points. How that
happens in semi-realtime is a mystery. This is no giant
animated gif. That would take too long to download.
There are a few image editing groups on usenet.
Maybe someone out there really knows.

It's just a series of bout 40 photos. What's the big deal?

Its an imaginative way to show the fly, but I don't see any fancy graphics.

Yes, but I doubt anybody took 40 photos.
I think they took fewer exposures, and then used software to
interpolate the intermediate frames.

Why not? It wouldn't be hard to do with a still camera, especially one
that shoots sequences.

Way out of my depth, but I'm curious. Is there anything visible which tends
to support one theory or the other? Or are we dealing with speculation
based on considerations other than what appears on the screen?

I went back and looked again and I think it is "just" a lot of still photos

Using a trackball type "mouse" and being as careful as I can I get distinct
jumps and can not, ever, find a postion between those jumps.

Camera mounted on tripod, fly mounted on rotating holder, unimaginable
patience ... all it would take G

The most interesting part to me is the control of rotation by the mouse,
which makes it more than a simple animation with 40 photos. Now if I could
have true 3D, being able to look at the fly from any angle (i.e. top and
bottom also) rather than simple rotation......

True. Also the lighting is pretty darn dark on some of the cooler
flies....

Now you're talking about a whole lot of pictures - or the use of interpolation
software previously mentioned.

fwiw, Quicktime VR supported mouse-driven 2D rotation long before it showed up
in Flash.

Years back when digital cameras first came out, I used VR to create all kinds
of 360° views of building interiors and exterior scenes. This is quite a bit
tougher to do than these fly images, because you had to rotate the camera, not
merely the target in front of a fixed camera position, and it's a rare camera
(indeed, perhaps none) that places the tripod mounting hole exactly in the
center of the "film" plane. So the first thing I had to do was make an adapter
that properly aligned the center of the film plane to the rotational center of
the tripod. Such devices can be had via mail order these days...
