Redoing my Synths on another account I notice that while orienting the Synth only some of the Synths photos are shown to use for orientation. Also, after orienting the test button is not enabled. Such Synth fails to dive-in properly on Bing Maps. I can't recall I have experienced these before. Last year I used win 7 32-bit. Now I use IE9 on Win 7 64-bit.

Checked on win7 32-bit. Same issues.

Hi, Joscelin, 

Ever since geo-alignment was introduced, we have only been allowed to use the largest cluster of photos/largest point cloud in a Photosynth to align to the map. 

Back when geoalignment was new, I requested that we be allowed to align each cluster independently, as that would allow us to manually tell Photosynth how unconnected clusters connect: http://photosynth.net/discussion.aspx?cat=01b6f15f-42eb-49cb-a221-ed56615e1c47&dis=edb44f3b-b687-4954-97c5-81f01b208513

Hi Nathan, is this also true for 100% synthy Synths? And how about the greyed out TEST button, which results on a non-functional dive-in? Any clues?

Well... you would expect '100% synthy' to mean that everything is connected, but sometimes the website awards a high synthy score, even though some of the images are only barely connected. The Photosynth team calls these 'portal' images as they act like a gateway from one large cluster to another but are a very weak connection. This means that sometimes when you look at a synth in 2D view, some of the images in the largest/only cluster may not actually belong to the same point cloud. In that case, only the images which are attached to the largest point cloud are available for alignment. 

If you still have the log files for your synths ( %temp%\photosynther ), you can open them up and scroll down until you see 'Synth 0'. That will be the images on your largest point cloud. On a truly 100% synthy synth, that should be all that there is. If you see 'Synth 1', 'Synth 2', etc. then that is indication that there is more than one point cloud in the synth.

As to the greyed out [Test] button - I believe that in the current version of the editor (possibly all three versions that I remember) the [Test] button has always been greyed out after saving. I am not positive, but my instinct is that if you begin editing the alignment again, the [Test] button will be operational again. 

In my experience, this has no bearing on whether Bing Maps will dive in correctly or not. Once the point cloud is correctly aligned to the map, the map should swivel to the orientation of the photo in the synth which is currently set to be the first photo. 

If you could make a quick video showing one of your synths in the editor, aligned to the map and then show how diving in on Bing Maps does not correspond, it would help me better understand your problem. I don't know if you're already experienced with capturing video of your screen, but if not, I recommend Expression Encoder. Tips here: http://bit.ly/psfee

Thanks Nathan. This seems to concern my early Synths only. Yes, although they show 100% synthy, there is only a limited # of pics available for orienting. This is not a matter of the [test] button being greyed out after saving. I guess these things match up with a 100% Synth actually not being 100%. Seems to me it would be nice if such things would be a lot more clear from the site, in order to facilitate learning to create better Synths and trouble shoot them.

Maybe setting a photo as first photo while it is not in the orientation set is causing the issue.

Oh... I think you just figured it out with your last comment. That makes perfect sense.
