 The main Objects are:
-  * **PointCloud** : A **Node**, i.e. an object that can be inserted in a GroIMP graph. The PointCloud is responsible for the display of the points by implementing **CollectionDisplayable**.
+  * **PointCloud** : A **Node**, i.e. an object that can be inserted in a GroIMP graph. The PointCloud is responsible for the display of the points. In the case of **PointCloudD** the display is managed by implementing **CollectionDisplayable**.
   * **Cloud** : The representation of the data structure through which the point cloud data is accessed.
   * **Point** : The base interface that an object must implements to be part of a Cloud. In GroIMP, points are not limited to 3 dimensions.

 DisplayHandler require to be pinged to update their data. This can be done manually through the PointCloud using the attribute editor, or automatically when some tools are applied on the PointCloud.

 The picking is also managed by the PointCloud through the DisplayHandler. By default, the Points are picked on the 3d scene, but a [[3d-guide:view_manipulations#navigate_in_the_scene|navigation mode]] enables to pick the DisplayHandler.
