API function: algo.explodeConnectedMeshes.

Each occurrence is subdivided in one occurrence per surfacic connected subset () + one for the non-surfacic elements ( and ).

A list of N (+1 if there are non-surfacic elements, ie, lines or points) occurrences, where N is the number of surfacic connected subsets in the parent occurrence.

The following images visualize one color per connected component in the PixyzUI before (first image) and after (second image) a call to algo.explodeConnectedMeshes:

The scene treeview on the left also shows that a component has been subdivided into 10 new ones.

There's a single parameter to this algorithm. It determines how non-manifold edges (i.e., edges with more than two adjacent polygons) should be handled.

When , then non-manifold edges are considered to be a border of a connected component. In that case, each polygon adjacent to the non-manifold edge is considered to reside in a different connected components (unless they are connected via a sequence of manifold edges and polygons elsewhere).

When , then the polygons connecting at the non-manifold edge are considered to belong to the same connected component.
