DAVID Laserscanner is a software package for low-cost 3D laser scanning. It allows scanning and digitizing of three-dimensional objects using a camera (e.g. a web cam), a hand-held line laser (i.e. one that projects a line, not just a point), and two plain boards in the background. Its most distinctive feature is that the laser line can simply be swept over the object by hand (like a virtual brush) until the results are satisfactory.
