    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.

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

Adjust the representation of a point cloud

  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 .

    2. In the color picker, select a new color.
