I am a little taken aback by their pricing strategy, or maybe I'm misunderstanding it. If you purchase this, you have to pay (at least) $500 a year, for hosting, and $20 per scan, if you scan more than (say) 6 times in a month?

I too was confused but then I realised this isn't meant for fun hacky 3D-mapping. It's meant to sell stuff for the home and I think that's unfortunately going to limit the reach of this technology. The only third party type of business that might be able to make use of this is a real estate company for obvious reasons. I guess they have a public API that can pull the data but even then that requires somebody with the…

Right? Except it's not a $500 paperweight. It's a $4,500 paperweight with an additional $500 a year overhead.

Depending on how effective Project Tango is, this technology might be short lived. Maybe there's some manual labor that has to happen on their end before your files are ready? Otherwise I just don't understand the cost. Storage and bandwidth couldn't possibly cost $50/mo.

Sometimes I really do lament the fact that everyone decided that an ongoing subscription model is the way to go for everything.

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.

It doesn't look ready for consumers. The scans looks like lumps of clay. Shouldn't it look exactly like the spaces it scans ? Thats what scanners do. When I scan a document, it gives me pretty sharp copy. I wouldn't pay for scanner that give me very fuzzy copy of a document, at least i would not try to sell it until i perfect it.

When you scan a document, it produces a two-dimensional image. This is producing a traversable three dimensional space. It's a very different problem for so many reasons, and I don't think it's reasonable to expect the same fidelity in the result in the near future.

As a consumer I don't care how difficult it is for you to implement it. Its the harsh reality of the consumer market.

Can anyone recommend some open source code to experiment with at home? Maybe fed by Google Tango or Microsoft Kinect?

http://pointclouds.org/ has a subproject called (http://pointclouds.org/documentation/tutorials/using_kinfu_l...) that you can feed with a kinect or a similar device. It's quite fun!
