This SOP combines fractured pieces into larger clusters, either by adjusting the
name attribute or by grouping the intracluster and intercluster constraints.
The optional incoming
cluster attribute on the constraint geometry points can be further refined with the Add Cluster Noise and Random Detach parameters.
Specifies the constraint points to cluster.
Specifies how to apply the clustering to the input geometry.
name primitive attribute to combine pieces into clusters.
This will result in fewer objects in the simulation.
The constraint geometry is also updated to reflect the new pieces.
The input geometry is not modified, but primitive groups are added to the constraint geometry to identify constraints between clusters, internal constraints in a cluster, etc. This can be used with the RBD Constraint Properties SOP to, for example, create stronger constraints between pieces in the same cluster. With this approach, the clustered chunks may be broken apart during the simulation by breaking the constraints within a cluster.
Cluster Name Prefix
The prefix applied to the name of each clustered piece.
Fuse Clustered Pieces
Fuses together each cluster’s pieces according to the Distance threshold, and removes the interior faces between those pieces.
A group containing the interior polygons of the fractured geometry (e.g. the Interior Group from Voronoi Fracture).
The maximum distance to fuse points together.
Dissolve Exterior Cluster Edges
After fusing, dissolves exterior edges that are shared by primitives from different source pieces. This can be useful for removing fracture lines from clustered pieces.
The name of the group containing constraints between pieces in the same cluster.
Cluster to Cluster Group
The name of the group containing constraints between pieces in different clusters.
Cluster to Piece Group
The name of the group containing constraints between a piece that is in a cluster and a non-clustered piece.
Piece to Piece Group
The name of the group containing constraints between non-clustered pieces.
The name of an integer point attribute on the input constraint geometry.
Adds cellular noise to the input points of the constraint geometry. The default behavior is to preserve the existing values of the Cluster Attribute if it exists on the input constraint geometry.
The offset of the cellular noise added to the input points.
The jitter 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.
Randomly detach pieces from clusters.
The random seed used for detachment.
The probability that a particular piece will be detached.
