1 Introduction
Thank you for purchasing a FastSCANTM 3D laser scanner. Your scanner will quickly
and conveniently digitize the surface of any object into a series of points that fit to-
gether in 3D space. The FastSCANTM software then transforms this data into a detailed
3D object, in a file format that suits your needs.
The FastSCANTM software combines overlapping sweeps and eliminates redundant
data to create a complete surface. This can then be further processed using mathe-
matical functions called RBFs (Radial Basis Functions) to create a smooth watertight
surface in the form of your scanned object. The resulting 3D object can be exported
in a range of industry standard formats for use in other applications.
Please ensure you have read Section 12: Safety Guidelines before using this product.

2.2 Computer Requirements
•Windows Vista or XP (SP2) 32 or 64 bit OS, or Windows 2000 SP4.
◦1 GHz Intel Pentium III or greater
(2 GHz Intel Pentium IV or greater recommended for RBF processing)
◦512 MB RAM or greater.
◦USB port.
•OpenGL compatible hardware accelerated graphics adapter in 32-bit (true color)
mode (minimum resolution 1024 x 768).
2.3 Installing the Software
Important: In order to install FastSCANTM ensure you have administrator privileges
on the computer.

it doesn’t, open the FastSCANTM CD folder manually and double-click on the
FastSCAN Setup.exe file to run the wizard.
2. You will be guided through the installation of the FastSCANTM software. Install
the FastSCANTM files in the default directory. The setup program will also install
the USB drivers automatically. During the process you may be alerted that
the FastSCANTM USB software has not passed Windows Logo Testing—if this
happens click the Continue Anyway button. You will be prompted to restart
your computer if necessary.
3. When the software has finished installing open the CD folder, double-click on
the license file FastSCAN.lic.exe and follow the instructions.
4. After the license file has installed double-click on the wand(model#)CFG.exe
file to install the calibration data for your particular Wand.
