3.1 The Scanning Environment
An area of subdued lighting is ideal for scanning, with no external light entering from
windows. Scanning errors can arise when the scanner’s camera views direct sources
of strong, bright light, such as the sun or a powerful incandescent light.
Keep the scanning area at least one meter away from the Processing Unit, computer,
and any other significant metal objects. A wooden table is an ideal surface on which
to place objects for scanning.
For best results always position the Transmitter as close as possible to the object that
you are scanning. It is usually most convenient to place it behind or under the object.
Figure 6: An example of scanning a model. Note the wooden table, placement of the
Transmitter, and the position of the Wand.
In the default Transmitter is Reference mode it is vital that the object remains station-
ary relative to the Transmitter during the scan. If the object cannot remain stationary,
then the Transmitter may be attached to the object, or alternatively the Reference Re-
ceiver may be attached and Receiver is Reference selected in the Scanner menu (refer
to Section 3.5.1).
