Display Control
The number of cloud points displayed graphically can be controlled using the Cloud Display Control (View>Cloud Display Control Ctr+T). This utility provides the ability to adjust a global thinning factor which reduces the overall number of cloud points displayed as well as a cloud point size control.
As a Point Cloud is rotated or translated in the graphic view, the dis- play resolution of the cloud will reduce automatically and will be re- stored once the movement is stopped. Control over the extent of this additional thinning is also provided as part of the Cloud Display Control.
-
Thin. The visual thinning factor applied. If set to the 8, for example, only 1 point in 8 will be displayed. Note that the thin slider control will be disabled when AutoZoom is enabled.
-
Size. The number of pixels used to display a point cloud point.
-
Rotational Thinning. This section controls the additional thinning during graphical moves and rotations. Either or both of these rotation limits can be applied:
-
Percent. If set, Rotational Thinning is controlled by a percent- age value from 0-100 where 100 is no additional thinning.
-
Limit. If set, Rotational Thinning is controlled by an upper limit of the number of cloud points displayed. In other words no more than the Limit number of points will be displayed graphically.
-
AutoZoom Enable. Enables/Disables a zoomable display in which a limit can be set for how many cloud points are displayed graphically within the viewing window. As you zoom in more points will appear until the cloud is displayed at full resolution, while zooming out reduces the total visible in a single area in favor of holding the max display value.
-
When a live instrument is connected to in the job the total number of cloud points visible at one time is limited to 200,000 points. This prevents potential loss of data due to slow downs resulting for graphic display issues. Cloud thinning can be regulated below this threshold but can not be increased beyond the threshold until the instrument is disconnected.
-
Point Selection. This option is used to help select points that are closest to the viewpoint when selecting points from a cloud with multiple layers.
