Organization/Visualization point clouds
By default each object is displayed with LOD – Full Range. This means just enough rendering
(also based on distance) to allow the user to see what the object is. Notice how the surface of
the pole is not perfectly round. And if zooming out it will at some point actually become square,
taking in the level of detail a user needs at a certain range.

The cylinder now has a smooth surface
displayed which will always be
maintained.
 Do not by default switch all objects to Highest Complexity as this will impact
system performance.
3 Unify a Point Cloud / ModelSpace
In a ModelSpace containing a registered set of scans and a large number of point clouds,
performance is improved by the cloud unification process.
When running a unification process all point clouds will be combined into one single efficient
point cloud object.
During this process a point reduction with a selectable average point distance over the whole
point cloud can be done.
The Unify command always concerns only the ModelSpace selected. A new copy containing all
individual scans can always be re-created via creating a new ModelSpace.
 Depending on the size of the database, the unify process can take a long time
and requires 6x the size of the database of free space on the computer’s hard
disk.
