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

Is it possible to export the point cloud in an ascii file format, with X,Y and z point data?
For Photosynth 1 synths (made with the Photosynth desktop application for Windows), it is indeed!

Check out SynthExport by Christoph Hausner ( http://photosynth.net/userprofilepage.aspx?user=christoph_hausner )
http://bit.ly/synthexport

Christoph is currently working on adding the ability to save the data from Photosynth 2 synths (made in Windows Azure through http://photosynth.net/preview ) as well as stitched panoramas from ICE, Photoshop, Windows 8.1, and Photosynth's mobile panorama apps as well, but isn't finished with that part yet. http://photosynth.net/discussion.aspx?cat=ceca0f30-0f7c-4468-811a-32b623ea8563&dis=cde6b799-8a9d-4ab3-ad00-412e25be4214
Henri Astre ( http://photosynth.net/userprofilepage.aspx?user=dddexperiments ) also made a data exporter for Photosynth 1 synths: 
http://bit.ly/photosynth-toolkit

It downloads the primary (largest) point cloud from a synth but also has the ability to download the photos that compose it: both a thumbnail version (which stores all the EXIF metadata) and the original resolution (and it will automatically put the metadata back into the full resolution photos if you download both).

Point clouds from ICE, I never realised there were any there in the first place, so glad he is working on supporting version 2.

Well, although image keypoints are detected between image borders and matched in stitched panoramas, this data is not saved in the output cube map.

Rather, as panoramas go here on Photosynth.net, ever since their mobile panorama apps launched in 2011 we've had users asking here on the forum for a way to save a local copy of their panos that they'd uploaded to their Photosynth.net account.

This applied for folks who had deleted the local copy off their phone individually, folks who had uninstalled the app (thus deleting all local data), etc. and has been an ongoing sore spot. When making panoramas in ICE or Photoshop to upload to our account, we retain access to the input images and also have the ability to save a local copy, but with Photosynth's mobile panorama apps this is not the case.

So what is planned for SynthExport as far as panos go is to just download the cube faces + then stitch them in ICE locally to give one a local copy.
