3 space data acquiring

[Nano]

Greetings Experts,

I'm about to embark on building a device which can determine the
dimensions of a room from a point source, using a laser distance
measuring device (laser tri-angulation). Now in order to do this i need
to spin on 2 axis, aquiring spherical measurement data. In order to do
what i wish to do i need some very fast sample rates on my laser
distance measuring device. The problem now becomes that my device costs
more than my budget. However, if i down scale my spherical measurement
radius to 10cm, and have a 3mm resolution, I can aquire a spherical
measurement of the surrounding area in about 7 minutes. The only
problem is that this wont work for "wire-wrapping" a room from a point
source perspective. So my question is, does anyone have any ideas of
what practical application this 3D point source scanner would have with
a 5-15cm range and a 3mm resolution?
What i was thinking was that for now i could build my device such that
the device could do what i originally wanted it to do, but i'll just
have to replace the laser distance measurement device with something
better in the future. Thanx for your help

In my opinion, you will get much better answers if you post this same
question in comp.robotics.misc.

The exact opposite of your item is called a "flock of birds" and has

long been a stock tool of the animation motion capture folks.

Ascension is one source.
