The term scan state refers to whether scans have been loaded or
unloaded, and whether or not scan point clouds have been created.
These two states affect your ability to view scan data and the types of
operations you can perform in SCENE.

To perform certain processes, SCENE loads scan data into your
computer’s RAM. This is either done automatically as part of a SCENE
process, or manually. This feature is designed to reduce memory use
and increase the efficiency of SCENE. Loading scans can take several
minutes.
To load and unload scans:
In the Structure window, right-click on a scan, multiple individual
scans, or a scan cluster, and click either Load All Scans or Unload All
Scans and Pictures
(for a cluster), or
Loaded
(for individual scans).

ASTM defines a point cloud as “a collection of data points in 3D space
(frequently in the hundreds of thousands).”

A point cloud is also defined as “the computer visualization of the XYZ
coordinates that describe a physical object or environment. Each point
represents an actual point on the object or in the environment, and
collectively describes its shape and measurement... Synonymous with
raw scan data.”

When you use the Create Scan Point Clouds or Create Scan Point
Cloud commands in SCENE, the process is not related to visualizing the
point cloud; rather, it is related to back-end processing of scan data.
Several SCENE functions require this process. In many cases, such as
during Preprocessing , this process is automatic. However, you may need
to manually create scan point clouds to perform some operations, such as
creating clipping boxes in
3D View
.
To create scan point clouds, in the
Structure
window, right-click on a
cluster or a scan, and click Operations > Point Cloud Butto ns > Create
