Inclination from plane
This tool works on any set of point clouds. It allows you to add to the selected cloud(s) an extra color layer, representing the inclination of the points' normals with respect to a given plane that exists in the project. The inclination from plane ranges from -1 to 1 and is calculated as the scalar product between the points' normals and the plane's normal.
It's possible to use this command, e.g., to distinguish points on vegetation to points on soil (with regular inclination) and remove them is an useful application of vegetation removing.
