While working on my 3D editor back in 2010, I wrote a custom routine to automatically create a spherical mesh out of any set of arbitrary points in 3D space and got tired of testing it with semi-random points in space.
So, a quick trip to the local Canadian Tire (a weird of mix of hardware store, home improvement store, car part store, and house applicance store) to buy
– a 20$ laser level guide,
– add a web cam (already had it, worth about $10),
– a quickly written bit of code,
and voila:
I built myself a 3D scanner for 30$.
