ExplodeConnectedMeshes

Separate each connected component into a separate occurrence
Read time 1 minuteLast updated 4 months ago
API function: algo.explodeConnectedMeshes. Each occurrence is subdivided in one occurrence per surfacic connected subset (
polygons
) + one for the non-surfacic elements (
lines
and 
points
).

Outcome

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:
Segment Mesh Surface
Segment Mesh Surface
 The scene treeview on the left also shows that a component has been subdivided into 10 new ones.
Important
The last image was computed for this documentation only, the algorithm does not add any identifiers or colors to individual connected components by default.

Parameters

bool explodeNonManifoldEdges

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 
explodeNonManifoldEdges==True
, 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 
explodeNonManifoldEdges==False
, then the polygons connecting at the non-manifold edge are considered to belong to the same connected component.
