Photosynth of a building in our neighborhood. This one only ended up being 45% synthy (up from 33% of a previous synth). The synth factor (or synthiness as M$ calls it) is a percentage of how well the image can be stitched together. In this case some of the detail shots were not able to be stitched in. I think that was because I was too close in a few of them. Also, I did not document corners as well as could have been which makes the tranistions a bit awkward.
From this, I have a better idea for how to do this again:
more pictures of corners and other direction changes. The software must be able to figure out that it is going around a corner
possibly several pictures between a wide angle and a zoom in of detail.
more up and down shots overall.
You need to run the creation tool in Windows, but the viewer can be used on any Silverlight platform. Click through to see what the synth looks like.
