Point clouds in GroIMP are composed of a PointCloud, a Cloud and Point. They are defined as follow:

• 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.
• 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.

These three Objects implements CloudContext, meaning when any of the three is selected, you can access the Cloud structure handled.

The PointCloud objects can be modified with a set of available tools, shape fitting, and clustering
