 Gary,
 There is another option for producing highly accurate 3D models using
 software, computer and a good camera .  There are several products out
 there.   We use one called Photomodeler.  It's based on phogrammetry -
 essentially numerous stereo pair photographs to create measured 3D
 models.  It's used for architectural restoration, crime screens, plant
 engineering, etc.  The same points are identified on various photographs
 and the computer relates that to a point in 3D space.  Surface maps can
 also be extracted.  The software is under $1,000.00 and it's relatively
 easy to use.
