Can’t seem to get something to synth right? Curious about what lens is best? Ask your fellow Photosynthers here.


Topic: Just simply jump from one pano synth to another?

in 1995, It appeared simple to take a QuickTake 100, 28 pictures per panoramas, stitch them on a Mac and link them with hot spots in QuickTime VR.

In 2011, can someone please tell us how to do that simple feat with Photosynth?

The students have already taken a lot of panoramic synths around the school (20 some classes), and we would like to publish and link them for a school virtual tour.

Thanks in advance.

Hello, estroissynthfdl, 

Photosynth currently hosts two different types of imagery: 
1) photosynths released 2008 (multiple photos taken from many different positions, looking at the same object or set of objects, resulting in an underlying sparse 3D reconstruction of the object or scene called a point cloud and additionally the ability to move all the way through an environment moving from photo to photo)

2) panoramas added 2010 (multiple photos taken from one single position, looking at the same object or set of objects, resulting in a single fused photo which is simple to pan through, but contains no depth information for the scene)

In other words, photosynths are essentially what you're after and have been since 2008, except that: 
a) not every position will be a panorama, but a single photo and 
b) instead of manually linking from one photo to another, you instead take the photos in such a way that they can be automatically linked by Photosynth.

Here are a few example photosynths for you to browse: 
(The original viewer requires 1: Windows, 2: Photosynth, and 3: either IE or Firefox 3. Firefox 4 - 9 breaks the D3D viewer.)

Linking photosynths to each other so that you can move through the world as though it were one large photosynth has long been the dream of Photosynth ( http://getsatisfaction.com/livelabs/topics/linking_synths ), however the legal side of displaying multiple people's photos together which have been uploaded with different photo licenses has been a tough nut to crack and has held back progress, although the technical side is certainly possible. 

Since panoramas are also a part of the equation now and 'spin movies' (think QuickTime VR 'Objects' except with some ease of shooting and technical presentation improvements) have also been demoed ( http://bit.ly/spinmovies ), these are naturally things which we all would like to link together and browse as one. 

To this end, the team at Bing is hard at work on a new project entitled Read/Write World which will hopefully bring much of this linking to fruition in beta form next year. Information: http://bit.ly/readwriteworld

In the mean time, I see a couple of options: 

Option 1) The simplest solution, if you have had the children shoot with panorama methodology, rather than shoot for 3D reconstruction is to: 
a) Tag each child's photos' 'Author' metadata with their name (or if this is deemed a privacy|security liability, then credit the photos with the class's name or the school's name)
b) If the photos were truly shot as panos, rather than synths, you may want to upload them as panoramas by using Microsoft ICE http://bit.ly/microsoftice or the Photoshop to Photosynth panorama publishing plugin: http://bit.ly/pstops
c) Geo-tag and Geo-align each individual panorama on Bing Maps. (Just click the [Edit this...] button underneath each pano|synth.)
d) For the tour, you could simply get a link to the appropriate part of Bing Maps with the Photosynth map app turned on and easily click on any of the Photosynth pushpins to enter a panorama or a photosynth.

Option 2) Attempt to create a single large photosynth from all existing photo sets by combining them with additional 'bridge' photos.
a) Tag each child's photos' 'Author' metadata with their name (or if this is deemed a privacy|security liability, then credit the photos with the class' name or the school's name)
b) Teach some of the students to take photos which begin at a point within one of the existing panoramic photo sets and walks through the environment until it reaches the next so that the two are automatically linked by Photosynth.
c) Add 'Highlights' to the final synth, when you have gotten everything to link together the way you want - at least one per classroom to begin with.

This option necessitates learning to shoot for 3D reconstruction, rather than old fashioned panoramic shooting.

Option 3) If you have someone on your staff who is familiar with Javascript, you can actually create your own hotlinking system. 

Take a look at http://stargate.mgm.com/photosynth/ and note that they are changing the caption on the webpage (just under the title of each synth) based on where you are inside the synth viewer. This sometimes includes hyperlinks which could be to other synths or panos or simply a different perspective inside that synth.

Here's the Javascript API for whoever wants to attempt this: http://photosynth.net/api/docs/default.html

Two examples of Option 2 above would be: 

1) these quick seven panoramas I shot for fun on Sunday afternoon after church on my phone. http://www.bing.com/maps/explore/?#/lsm2l6kslbvjcbow and 

2) Thomas Hayden's collection of panoramas at the Oregon Museum of Science and Industry:

Oops. The two links I posted in the previous entry are examples of Option 1, not Option 2.

Hello natelawrence.

Thanks for the precise response. I will read it carefully, follow links and come back to you about it.

The clarity of your responses made me realize I could have been more explicit in my original request.

We do shoot fully complete bubble stiched or cylinder pictures (panoramas added 2010 taken from one position) alike the QuickTime VR of 1995 and want to link them together so that web visitors can go from class to class using hotlink-like QuickTime VR of 1995.

Is a virtual tour possible in the panoramas added 2010 taken from one position technology imitating QTVR from 1995.

FDL, I was hoping that I would hear back from you and that your question in your last post would have been answered by what I typed the first time.

Since it's been a week now and you have yet to reply, I'll assume that you're waiting on my reply.

In short, no, Photosynth does not, at the time of this writing, support linking multiple stitched panoramas (much to my chagrin), nor does it yet support correctly projecting cylindrical or spherical panoramas *within* the larger context of a single photosynth.

Photosynth has never (to date) been about the manual linking of one image to another. It is entirely about the automated linking of images. It does this very well with individual images and the ability to move the camera through + around the environment (3D stitching) is a leap beyond single panoramas (2D stitching).

I believe that next year we'll see the ability to derive 3D reconstruction from multiple panoramas as we currently can from multiple photos.

Hi there Nate, Sorry for the long delays. It's been a big pull at school and this morning is Xmas vacation starting. I'll look into it now that the pressure is off. Sorry to hear that Photosynth is not geared to what Quicktime VR did in 95 but one of your links reminded me that code is powerful and it might be done in Javascript or HTML 5 for example. Maybe I should even use be using another software. Anyhow, i'll get to it during the holidays and get back to you here on this page. Merry Xmas 2011 and Happy New Year 2012!
