4 Processing Scanned Data
4.1 Surfacing Options
The FastSCAN
TM
software deals with three surfaces: the Sweeps Surface, the Basic
Surface and the RBF Surface. Figure 16 shows the path taken to generate these three
surfaces.

TM
program.
The display view may be changed between the Sweeps Surface, Basic Surface and
RBF Surface. If processing is required to obtain a view it will begin automatically
when that display option is selected.
4.1.1 Sweeps Surface
The Sweeps Surface is effectively the raw data gathered by the scanner
and is made up of a number of individual sweeps of the object. The
(individual) sweeps may overlap and intersect each other, contain holes
and may have been scanned with differing resolutions.
