Attach and manage point clouds

Point clouds are groups of measured points on the surfaces of objects created with 3D laser scanners. You can attach point clouds to your project in the 3D model view. After adding a point cloud, you can adjust its appearance according to your needs.

Attach a point cloud

  1. In the 3D model view, click Point clouds in the side pane.
  2. Depending on the location of the point cloud file, do either of the following:
    To Do this

    Add a point cloud from your computer or a drive

    1. In the Point Clouds side pane, click Add.

    2. Browse for and select the point cloud file.

    3. Click Open.

    Trimble Connect for Windows downloads the point cloud file and adds the point cloud in the model.

    Add a point cloud using a URL address

    1. In the Point Clouds side pane, click Add URL.

    2. Type a name for the point cloud.

    3. In the URL box, type or paste the URL address to the point cloud file.

    4. Click Add.

    A Pointclouds folder is added in the project root folder. When you are working in Trimble Connect 3D viewer, you can view the point clouds from the Pointclouds folder.

Access point clouds added by other users

To access point clouds added by other users, you need to:
  • Have access to the folder where the point clouds are stored. This means that the point cloud files and folders need to be uploaded to the server.

  • Download the files from the server to your local computer.

Adjust the representation of a point cloud

  1. In the 3D model view, click in the side pane.
  2. Select the point cloud whose representation you want to adjust.
  3. Do any of the following:

    To

    Do this

    Adjust the depth perception

    The Eye-dome lighting (EDL) effect improves the depth perception of the point cloud. You can adjust the EDL settings according to your needs:

    • Hold down the left mouse button and drag the Thickness and Strength sliders to increase or decrease the outline thickness and strength of the point cloud.

    Activate or de-activate the EDL effect

    By default, the EDL effect is switched on.

    • To de-activate the EDL effect, click the EDL button.

      The EDL button is dimmed.

    • To activate the EDL effect, click the EDL button again.

      The EDL button turns blue.

    Increase or decrease point size

    • Hold down the left mouse button and drag the Size slider to increase or decrease the size of points.

    Increase or decrease point density

    • Hold down the left mouse button and drag the Density slider to increase or decrease the density of points.

    Change the coloring of the point cloud

    • Select a Color by option:
      • To use the default color values, click Defaults.

      • To use elevation values, click Elevation. Then, adjust the coloring by dragging the Top, Middle, and Bottom sliders or typing values in the related boxes.

      • To use classifications for point coloring, click Classifications. Then, adjust the coloring by dragging the Top, Middle, and Bottom sliders or typing values in the related boxes.

        You can also adjust the classification color that is used, or hide classifications.

    Adjust the classification color

    1. In the Classifications section, click the current classification color .

    Hide classifications

    • Click on the left side of the classification color.

    Hide a point cloud

    • Click on the left side of the point cloud.

Update a point cloud

If you modify point clouds in the project detail view, the changes are not automatically updated to the 3D view. To update point clouds:

  1. In the 3D model view, click in the side pane.
  2. Click the Refresh button in the upper-right corner of the Point clouds side pane.

Remove a point cloud

  1. In the 3D model view, click in the side pane.
  2. In the Point Clouds side pane, click a point cloud to select it.
  3. At the top of the Point Clouds side pane, click Remove.
