I'm surprised there hasn't been more improvement in the scans - I would think given the restricted domain of interiors it'd be possible to straighten out edges and things.

Yes. The thing that sticks out the most to me is the poor treatment of edges. One possible reason the edges look bad is that meshing algorithms that take into account sharp edges can produce unrealistic mesh topologies that are difficult to work with. Bad mesh topologies can wreak havoc on some operations like texture mapping, which they obviously use quite heavily. There are algorithms that can clean this up, but it is a messy and computationally intensive business.

Or it could just be poor data from the scanner -- that would be unfortunate. Some of the artifacts are so bad that it would seem to suggest that this is the case (the corner of the countertop in the kitchen is quite bad, or the protrusion in the wall above the entry-way into the kitchen, for some examples). It's hard to tell from looking at the processed result. I wonder what the raw scans look like.

Very cool product though, even if it's rough right now. I can see this looking nice in the future.

Yes, and since everything is triangulated too early (it seems) there's no level-of-detail. The scan in the video looks like puke. The scan that plays in the background when you load the page first looks much better.
