I would love to be able to export photosunths point cloud into an external 3D program to be used as reference for 3D modelling...

even better,would be to let the user create geometry by selecting key particles within photosynths point cloud to become vertex points of a basic polygonal object.

photosynth should then be able to take the photos used within the point cloud, and stitch together a texture map that can be mapped onto this polygonal geometry.

Using creative expressions panoramic photo-stitching technology to stitch together multiple images into a seamless texture. The Photosynth texture map can also utilise deep-zoom technology to have multiple levels of detail.

Absolutely Second.
Just a automatic export of a point cloud to something like dxf would be insanely usefull.

If Photosynth were to export to DXF, would it be sufficient if it is just the points - no lines or polygons?

I think my only beef with export to DXF (which would be COOL, by the way) is that the DXF format has no real way to attach color information to an object.  Ok, ok, it does, but it's not what it was intended for, and it would be a pretty kludgy way to get that done.

It might be better to be able to export to a format that's designed for 3D modeling, like .OBJ or .PLY, where color information on an object-by-object basis is already part of the whole idea.

Having Photosynth mesh the point cloud would be neat, but wouldn't be strictly necessary.  There are applications out there already that do a good job of this.

Getting at the point cloud is already possible and although I too would like to see a simple "Export Pointcloud As:" dropdown list of formats, what I would like to see (which I have not seen anyone reference yet) is a way to include the positions, orientation, dimensions, etc. of the camera frusta in the model, à la Photo Tourism, the Photosynth Tech Preview, (and even the current Photosynth data, of course, although it is no longer visible except by iSynth).

To me, the model is incomplete without this data, and that data would certainly be described using "lines or polygons". If you had this camera position information you could go about finding someone in the Blender community or other similar communities who could help you go about beginning experimentation with dense reconstruction on your own time. Certainly I expect community driven efforts to be far less polished than that of professional Microsoft devs and researchers, but you could get a sneak preview Tom.

even just XYZ excell spreadsheet would be useful... or mabe XYZRGB, for import into better software.
