Microsoft Releases Photosynth 247
Spy Hunter writes "Photosynth has graduated from a 'tech preview' to a complete service. Now you can upload your own photos and have them automatically transformed into a 'synth': a 3D fly-through reconstruction of your home, your vacation, or anything else you can take pictures of. Learn more about Photosynth at the official blog, see what Walt Mossberg has to say about it, or just go try it out right now." According to Mossberg, Photosynth works on PCs using IE or Firefox, but not yet on Macs. We've been discussing Photosynth since its introduction.

It does make them 3D (I remember seeing the video of the first demo last year I think it was). But it's not quite precise enough to be used for level design, or at least it wasn't back then. Still very cool though :)

Remember kids, set Graphic Acceleration to Full!
Minimum System Requirements
Important: Photosynth makes heavy use of your graphics hardware. If you have an older graphics system, Photosynth may not run. Also, Photosynth requires that your graphics acceleration be set to full.
Operating System: Only Windows XP (SP2 or SP3) and Windows Vista are supported at this time. Running Windows on a Mac? Photosynth runs under Boot Camp only. Parallels and other VM software cannot run the viewer.
Web Browser: Internet Explorer 7, Firefox 2, and Firefox 3
Memory: 256 MB of memory is a bare minimum; 1GB is recommended.
Graphics: Minimum 32MB of graphics memory required, 64MB or more is recommended. Photosynth runs on some DirectX6 capable cards and all DirectX7 cards.

So no Linux, probably not for a long time. Anyway, I can't see why things like this need to be a web service, so I'm waiting for the open-source variant.

Here's what it does:
Just like a typical panorama stitcher, it identifies similar points, then runs an optimisation algorithm in order to line those points up.
Whereas a panorama stitcher warps the images to match a particular projection, and optimises the points in 2D, PhotoSynth optimises the points in 3D.
The viewer application then lets you view the collection of photographs, as if they were hanging in 3D space -- in the right part of space -- and fade in and out of view as you stand in the right place to see them.
For quite a small number of photos, you get a BIG cloud of control points, and the application lets you view that cloud and hides the photos. Often the result is quite a good 3D model - it's clear that if you were to draw vertices between them you'd get a decent wireframe of the subject.
However, the application does not attempt to turn your photos into a convincing fully rendered 3D model. Rather it provides a spacial model for navigating between photos. It's always explicit that you are looking at one photo, with some other photos, dimmer, around it.
I think that's quite nice - that it doesn't pretend to be more than it is.
The slideshow option is rather neat. It simply steps through all the photos, but the transition between them shows you how they are spacially related.

Actually it doesn't do this at all. Time to at least give Microsoft some credit here, it does a pretty decent job of figuring out the 3D layout of everything and allows you to move around as much as you like.
It's obviously not EXACTLY right (Although I'd bet that with more pictures, it's more accurate) but it's close enough that you could make a pretty good "virtual tour" of just about anywhere with nothing more than a bog-standard digital camera.
It's definitely impressive.

You have been trolled by Microsoft. You have lost. Have a nice day.

I know its hard to beleive, but Microsoft -does- add APIs from versions to versions, and XP (and even more so Vista) have a lot of these. They're not going to spend months recoding a feature from scratch for 2k thats built in XP.

The short version: it's pretty fucking cool [ted.com].
The long version: The first time I saw the demo of Photosynth I was blown away. The second viewing wasn't as exciting which tells me that it's the concept of connecting 2D photos to a 3D model that's really amazing, a spatial way to navigate disconnected 2D data.
