Greetings Fellow Synthers,

I'm preparing a Photosynth presentation for a local computer society. I am collecting references and am in need of technical details of exactly how Photosynth works its magic. In addition to synthing, this includes Silverlight, Seadragon, and DeepZoom. I have a fair understanding of how most of this works, but could still learn more.

TIA.

InquiringlYours,

swami_worldsynther

P.S. Check out my latest synth of the Hiroshima A-Bomb Dome (~600 pix, 100% synthy, plus guided tour highlights) here http://photosynth.net/view.aspx?cid=b7b9e5b0-300b-4d0b-9f80-c5616e797c48 .

Swami...
Give me a couple of hours and I'll get you a link to a ton of interviews that should be exactly what you want.

Great! Tnx Nathanael:) Will stay tuned...

Depending on the form my presentation takes perhaps I can make it available to the synth community, or even give the talk to groups you could recommend. I enjoy this kind of thing. If it's a real possibility, we can work out the details.

P.S. How does a guy get his synth featured, anyhow? Would love to share my hard work on A-Bomb Dome w/ a wider audience. TIA.

FYI, have found some interesting details thru Wikipedia, but not sure what implementation is actually being used in Photosynth. Fascinating stuff. And luckily I have a background (BSEE-Elec Eng, w/ emphasis in computers and robotics, plus an extensive career in 3D graphics, including custom programming) to understand the details to a fair degree.

Hello Nathanael,

I've found some good references, but still look forward to what you might be able to provide.

TIA.

Swami... so sorry about leaving you hanging here. So much for a couple of hours. 

I don't know how much time you have left before you present and I know from other topics that you've posted that you've certainly found several of the same videos that I've collected over the years, but I'll link you to what I've listed so far.

I have some other videos that I still need to put in this list and there's still far more detail that I need to put into the spreadsheet as well as a few dead links that I've found where I have a copy downloaded but the online version has gone dark. I'll be patching that all up as time permits, but thought I'd better just get what I've got together in your hands as is.

Not all of what I link to here is technical by any means, but some is relevant to Photosynth's history.

You'll want Excel 2007 or 2010 to view it properly, but I'll post all updates to this link:

Swami, that's a great synth.  The centrally featured synths aren't usually quite that big.  Huge synths on the home page have an impact on page load time, so it's usually something under or around 300 images.  More on how to get your synth featured here: http://blogs.msdn.com/photosynth/archive/2009/09/01/getting-your-synth-featured-on-the-homepage.aspx

@madeeds: Tnx. I put a lot into the A-Bomb Dome synth and am pleased w/ the results. Too bad it's too big to be featured:( So, here's a smaller one in a similar vein: "Mayan Ruins of Palenque" http://photosynth.net/view.aspx?cid=0c71b1c4-8113-4bc4-bf4d-71ec4d9c6749 .
