Overview
Point Clouds
When a job contains point cloud data, that is imported into Infinity, this data can be managed in the Point Clouds tab.
If you scanned buildings, industrial plants or other huge objects you probably had to take your point clouds on several stations all around the object. It then becomes necessary to group the single point clouds as belonging together, defining one object. Especially, when you scanned more than one object and when you had to scan from several stations around each object, it becomes necessary to group the scan data. The grouped data also gives you a solid basis for future surface calculations.

To group point clouds into a point cloud group:
To group point clouds into a point cloud group:
| 1. | In the Inspector, select the Features tab and open the Point Clouds section. |
|---|---|
| 2. | Select the point clouds to be grouped and select New from the Point Clouds ribbon bar. |

The new point cloud group is created and added to:
The new point cloud group is created and added to:
- The Point Cloud Groups section in the Library of the Navigator. If the Point Cloud Groups subsection does not yet exist, it is created.For each point cloud group, the single scans belonging to it are listed.
- The Point Cloud Groups section in the Features tab of the Inspector.
Point cloud groups are always created with a default name. To change the name, click onto a point cloud group in the Navigator or in the Inspector and adapt its name in the Property Grid.
You can also create an empty point cloud group and add single point clouds to it later on.

Cleaning points
Cleaning points
If your point clouds contain random points, like points that have accidentally been taken while scanning a main object. These random points can be identified by Infinity and cleaned from the point cloud data in your project. As a consequence, you only see the relevant point cloud data in the graphical view.
To clean points:
To clean points:
| 1. | Select a point cloud or a point cloud group either in the Inspector or in the Navigator. |
|---|---|
| 2. | Select Clean Points from the ribbon bar to clean accidentally taken points from your point cloud data. |

Clean Points
In the Property Grid of the point cloud and/or the point cloud group, you see that the total number of points decreases to just the relevant points.
Any clean points operation removes the hidden points from the project and resets the hidden and visible subitem structure in the project library and in the project inspector. For more information, refer to Hide/Unhide.
Colouring Modes
Colouring Modes
Select between:
Select between:
- RGB colouring (natural colours).
- Intensity.
- SNR (Signal-to-Noise Ratio).
- Single Colour.
- Class.
For intensity and SNR, you can select a Colour Scale from the drop-down list. By default, MultiHue is set.
Colour Scale
For single colour representations, you can select whether the representation shall be By Layer (default) or by a user-selected colour.
By Layer
by a user-selected colour
For class colour mode, colours are derived from the mapping defined in the Project Classification Manager.
For all colouring modes, the last used settings are remembered when you open another project. By default, the project data is displayed in RGB mode.
Filtering points
Filtering points
To reduce the point density in the graphical view:
To reduce the point density in the graphical view:
Select Filter from the ribbon bar and select a percentage to which the point density shall be reduced from the drop-down menu.
Filter
The last used settings are remembered when you open another project. Select the option again to filter the points using the same percentage. The icon indicates which percentage has last been used. By default, the project data is displayed with 100%.
