Find Feature Neighbors from Triangle Geometry¶
Group (Subgroup)¶
Statistics (Morphological)
Description¶
This Filter determines the list of neighboring (surface sharing) Features of each Feature in a Triangle Geometry. The result is the number of neighbors (and the list of neighbors) of each surface meshed Feature. The neighbors are determined using the following algorithm:
- Triangulate each face of the polyhedron (in this case, each face is already a triangle within the Triangle Geometry)
- For each triangular face, query the Face Labels array to note the Features on either side of the triangle face
- For each Feature on either side of the triangle face, add the other Feature to the list of neighbors
- Count the number of unique features in each Features neighbor list
Parameters¶
None
Required Geometry¶
Triangle
Required Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Face Attribute Array | FaceLabels | int32_t | (2) | Specifies which Features are on either side of each Face |
| Attribute Matrix | FaceFeatureData | Face Feature | N/A | Feature Attribute Matrix of the selected Face Labels |
Created Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Feature Attribute Array | NumNeighbors | int32_t | (1) | Number of contiguous neighboring Features for a given Feature |
| Feature Attribute Array | NeighborList | List of int32_t | (1) | List of the contiguous neighboring Features for a given Feature |
