How to optimally visualize the Point Cloud in 3D

The 3D view loads and renders the point cloud of a project to allow the inspection of its reconstructed model.

Point clouds make use of LoD (Level-of-Detail) for fast and efficient loading in web browsers. It is possible to change the visualization settings, the size and number of points of the point cloud.

  1. Ensure to be in the 3D view.
  2. Click ic_settings_black.png: the following settings can be changed:
  • Background color: color in the 3D background.
  • Millions of points: points shown in the 3D view.
  • Show labels: labels on distance and area measurements can be activated or deactivated.

The rendering can rely on an adaptive or a fixed point size mode.

  • Adaptive: the size of the points reflects the LoD level (not the precision) that is being displayed. This can create disparities among the points where some appear larger than others.
  • Fixed: the size of the points does not adapt to the LoD being displayed. This mode can favor a better rendering in particular situations, especially those where models contain thin structures.

To change the point size mode:

  1. On the Layers tab of the left side navigation bar, select the Point Cloud layer.
  2. On the right, the Point Cloud details panel opens. Select Fixed or Adaptive as Point size mode.

To change the point size:
