Ericsson Labs is showing off an API for navigating through a three-dimensional interpretation of the world based on real imagery powered by Saab spinoff (the defense firm, not the car company) C3 Technologies on Sony Ericsson's upcoming X10 -- and in a word, it's looking impressive. The buttons for controlling the action are a bit hokey, of course, but don't worry too much about that -- this is strictly a proof of concept, and the important thing is that no matter how much panning, tilting, and swooping through the cityscape the demo-giver does, video output stays above 30 frames per second. Thank goodness for Snapdragon , eh? There's no indication that we'll see a shipping version of this app on retail X10s out of the box, but let's hope something awesome comes of this. Follow the break for video.
