The Glue Cluster operator sets the strength attribute of a glue constraint network. If a point has a cluster value of zero, all polygons connected to the point will have the Cluster to Cluster Strength. Otherwise, if a polygon connects points of the same cluster attribute value, they will get the Internal Strength.
The optional incoming
cluster attribute can be further refined with
the Add Cluster Noise and Random Detach parameters.
The name of the cluster attribute.
The bond strength between two pieces in the same cluster.
Cluster to Cluster Strength
The bond strength between two pieces in different clusters.
When one of the objects is hit, its impact value is spread along the glue network. This allows distant glue bonds that are weak to be broken prior to nearer, strong bonds. The impact propagations is the number of rounds of propagation to do. Impulses will not travel more than this number of bonds each solve step.
Add Cluster Noise
Add cellular noise to any input points with a zero cluster attribute value.
The offset of the cellular noise added to the input points.
The size of the cells for the noise added to the input points. This roughly corresponds to the size of the clusters.
The jitter of the cellular noise added to the input points.
Randomly detach pieces from clusters.
The random seed used for detachment.
The probability that a particular piece will be detached.
Color the points randomly according to which cluster they belong to. Points with zero cluster will all get unique values. Usually you will want to use a Primitive SOP to copy this to the actual geometry.
A set of two-point polygons describing desired gluing between objects.
This example shows how to use the gluecluster SOP and glue constraint networks to cluster together the pieces of a voronoi fracture. This allows clustering to be used with Bullet without introducing concave objects.
The following examples include this node.
