ZScan User Guide

If you want more details on a particular part of a piece, it is possible to increase the
resolution locally. The Increase Resolution function will increase the resolution of the
selected facets by 4. As you can see in the figure below, the resolution of a part of the
piece was increased in order to have a better view of the details. The effect of that
function is much more drastic than changing the resolution of the volume, hence it
should only be used locally because of memory constraints.
With the ZScanner 800, if you want to increase the resolution on a part of the piece, use
the High Resolution mode on the scanner. This option will turn on the third camera of the
scanner and acquire the laser curves directly in high resolution for better precision and
accuracy in these zones.
Decreasing Resolution
If some regions in the scan have had their resolution increased, it is possible to revert this
surface to the original resolution by using the Decrease Resolution function. As with the
previous tool, this acts on a selected set of triangles, which is, partially or completely, in
increased resolution. The following figure shows the decrease in resolution for a particular
zone. It is important to note that the selection made in this case was larger than the zone
that was actually decreased. The transition between increased and normal resolution
zone is done automatically and in a way as to make it as smooth as possible.
With the ZScanner 800, the laser curves acquired in high resolution mode can be
decreased in order to keep the high resolution only on the interesting details. This can be
useful to prevent unwanted details from being displayed on the digitized surface.
