Graph visualisation

Not really on-topic, but I've been always interested in graph theory:

(its a pdf!)

(It's about a new method to visualise large graphs, as you can see above.)

Laser Scanning Brings New Asset to Accident Investigations—and Surveyors

"Laser Scanning technology is revolutionizing many aspects of surveying and applied measurement, but it's been especially game changing in the rarified niches of forensics and accident investigation. The main strengths of scanning--speed, safety, accuracy, comprehensiveness, and the ability to return to the same data set and make new observations--serve forensic engineers especially well. Money is also a factor: when so much is riding on a court case, the extra costs associated with adopting new technology don't seem especially significant....."





I hope we will see some TLS documentation in the following Dexter episode`s..... :)

iTacitus

Augmented reality is a buzzword nowadays, and iTacitus is just about that. AR + tourist information, to be precise.

It would be interesting to see that in action, I'm curious, how fast will it spread.

On the other hand, it would be nice to see some AR applications while scanning an area! For instance, you could upload a part of the scanned points on your phone, and an AR software could show you, which parts of the area have been scanned already. The problem is, that you need instant GPS data for that, and you have to merge the different scanning position datas instantly. Without a specific software it could be quite difficult to do that.

However, links for iTacitus:

Sig.ma

Sig.ma is a visual browser and meshup generator, which will crawl the web for informations, semantic data, and even search inside applications.

You can get some information about laserscanning at this link: http://sig.ma/search?q=laserscanning (A nice start to get familiar with Sig.ma)

However, I find this tool rather interesting than useful. At least for now.... semantic web is the future.

Laser Strike at the Galactic Center

You should check out this one as well!! Interesting idea.
