About Clusters and Weights

A cluster provides a means of controlling a set of points as a group. The points can be NURBS control vertices (CVs), polygon vertices, or lattice points. (For more information on these elements, see chapter 12.)

Points that are members of a cluster have weight. As mentioned earlier, weight represents the amount of influence the cluster has over the points it contains. Weight is generally set between 0 and 1. A point with a weight of 0 will not move with the cluster. A point with a weight of 1 will move exactly as much as the cluster itself. Anything in between will make the point move a fraction of how much the cluster moves.
