Topic: best case and options

If I do a wall of a mountain and have 200 images but only 30 "stitch" could you at least try the rest then give an option to see each group or best case. This way I could fix the problem and move on or combine the groups skipping the missing area instead of starting over each time.

This older discussion is related: http://photosynth.net/discussion.aspx?cat=00581351-82d8-438d-a37b-7eadb3fb4991&dis=c68491bd-7a64-4a84-98cd-e034d120b5e7

The Photosynth team asks there about bringing back 2D View from Photosynth 1 (which clearly showed groups of matching photos, separated by the size they were displayed relative to each other). 

Their relevant quote is, "I'm considering bringing this idea back -- with the difference that in the new Photosynth only the biggest connected component would actually be visible in 3D -- the other photos would be there as thumbs, and you would have to look at the breaks between the sets to work out where you needed to add shots.  Would that help?"

Might I suggest that you try these shots in Photosynth 1 and just use 'Grid View' or '2D View' there to: 
a) check out the full resolution of all of the photos uploaded
b) see the groups matched
c) view each group in 3D

I know it means uploading twice for now.

Not a bad idea, Its more the time it takes to do it, if I could que them up that would help, but IE11 crashed and then you randomly have to do some over... I've taken 10's thousands of photos to upload and it kills my bandwidth and I'm lucky to have 30/5mb.

I wouldn't want to get your ISP irked with you for heavy uploading. 

PS1 does allow queuing up multiple synths to upload one at a time, for whatever it's worth, and it seems like you could fairly easily let that just roll overnight, but if you've got multiple new synths that you're trying to upload to PS2, then I can understand how that would be less enticing.

I'm all for using IE11, but what results do you get uploading in Opera, Firefox, and Chrome?

Doing the full 2D view is a lot more involved than I thought, so it may not be coming soon I'm sorry to say. Here's some things you can know: If you only got 30 out of 200 you submitted, then any other connected component is no more than 30 in size. (We always choose the largest). Also, the photo or photos directly adjacent to the end of the presented connected component are likely to be the problematic ones.

@PhotosynthTeam, that's unfortunate news about 2D view. =\
I'd be interested in hearing the technical challenges either here or some other venue (email?).

At first I thought that perhaps the limitation is merely OpenSeadragon not having support for Deep Zoom Collections at present, but wondered about this since you said that photos not in the primary cluster would only be shown as thumbnails anyway.

Secondly, I thought that perhaps the new pipeline simply doesn't try to match other images if it can't see how to progress beyond a break in the sequence (using different scene reconstruction than the pair seeding that PS1 used, since images are expected to loosely fit a preset reconstruction pattern) and that perhaps this would result in a lack of other connected components to present their groupings in 2D view.

After the dry years of being limited in Silverlight by lack of GPU access, it's quite disappointing to hear that now with WebGL, 2D view is too challenging.
PhotosynthTeam (6 months ago)
It's certainly doable, but it turns out we'd need pipeline changes + backend changes + under interface changes, and we're prioritizing other stuff higher right now.

Due to pivot being killed off due to silver lights death I think this could solve that problem too! I have 10,000 image pivots which are now useless. Check out www.comesagj.com 

also could anyone help make a better concept of the photosynths at the top? Maybe automated with a nice interface.
Nathanael (6 months ago)
@Photosynth Team, understood as far as priorities.

@Don't Panic, yes, thanks for bringing up Pivot! 
It took me a little while to figure out where the pivot embeds were on your site. http://www.comesagj.com/gallery.html

As a complete sidenote, I don't know that Pivot disappearing had so much to do with Silverlight being nixed as it did with Live Labs being dissolved into Bing in 2010 https://getsatisfaction.com/livelabs/topics/live_labs_is_joining_bing and Gary Flake leaving Microsoft as a consequence. https://twitter.com/flakenstein/status/26770365186

For others, here's an old suggestion from 2010 where Don't Panic and I were asking for using Pivot for Photosynth's current 'Explore' and 'Search' page functionality (if not within 2D view of a synth as well) http://photosynth.net/discussion.aspx?cat=01b6f15f-42eb-49cb-a221-ed56615e1c47&dis=990e7ab2-129e-4753-8e8f-40a9bc657054
