What are the implications for computing - how would it have to

2D mapping has been achievable for a while, but 3D mapping is a fairly
recent phenomena because it's not until recent years that enough
processing power has been available to handle this kind of task in
anything like real time. To a large extent the DARPA urban challenge
was all about 3D mapping and the accompanying sensor technologies
needed to support it.
DARPA challenges are mostly 2.5D, which is a much simpler problem. On
the other hand, 3D mapping is pretty cheap if you have decent
algorithms. The sensors are dirt cheap, so it is mostly knowing what
to do with the data once you have it.
