If the FastSCAN

program does not merge the overlapping sweeps correctly when it

blistering occurs as the Basic Surface jumps between the points in the two sweeps.

5.2.2 Decimation:

Increasing the Decimation value in the Generate Surface dialog box (Figure 19) re-

duces the number of points and triangles. This means a smaller export ﬁle and sub-

sequently faster rendering of exported scans when loaded into other programs. De-

creasing the value produces a more detailed mesh and a larger, slower ﬁle. Figure 22

shows the same object exported at two different decimation values.

The amount of blistering that occurs is also dependent on the Decimation parame-
