Generate Geometry Connectivity

Group (Subgroup)

Surface Meshing (Connectivity/Arrangement)


This Filter will generate the following connectivity data structures:

  • Per Vertex Element List: For each Vertex in the Geometry, a list of triangles to which the Vertex belongs

  • Per Element Neighbors List: For each primary unit Element in the Geometry, a list of Elements that share a common edge. If the mesh is non-manifold, each Element may have more than neighbors than Edges

Note that the resulting lists are stored with the Geometry object itself, not as separate Attribute Arrays. Some Geometries, such as a Vertex Geometry, may not have implemented the necessary connectivity functions, and will trigger an error when running the Filter.


Name Type Description
Generate Per Vertex Element List bool Whether to generate the per vertex element list
Generate Element Neighbors List bool Whether to generate the element neighbors list

Kind Default Name Type Component Dimensions Description
Data Container None N/A N/A Data Container that holds the Geometry for which to generate the connectivity

Created Objects

The resulting connectivity lists are stored with the Geometry objects, not in any separate Attribute Arrays.
