Find Element Centroids¶
Group (Subgroup)¶
DREAM3D Review (Geometry)
Description¶
This Filter computes the centroids of all Elements in the supplied Geometry. Currently, Edge, Triangle, Quadrilateral, and Tetrahedral Geometries are supported. The user must select where to store the computed centroids array; the Geometry used will belong to the Data Container in the path for the selected for the centroids.
Element centroids represent fundamental topological information about the Geometry, and thus will be stored within the Geometry object when computed. This Filter will additionally store the centroids as an Attribute Array within the data structure. The array represents the (x, y, z) coordinates of the centroid. This Filter will enforce that the centroids are stored in an Attribute Matrix that matches the fundamental Element type of the selected Geometry:
| Geometry Type | Destination Attribute Matrix |
|---|---|
| Edge | Edge |
| Triangle | Face |
| Quadrilateral | Face |
| Tetrahedral | Cell |
This Filter may optionally create a new Data Container that holds a Vertex Geometry whose point positions are the computed centroids. A Vertex Attribute Matrix will be created for this new Geometry to store Vertex-level information.
Parameters¶
| Name | Type | Description |
|---|---|---|
| Create Vertex Geometry from Centroids | bool | Whether to create a Vertex Geometry from the computed centroids |
| Vertex Data Container | string | Name of the Data Container to hold the new centroids Vertex Geometry, if Create Vertex Geometry from Centroids is checked |
| Vertex Attribute Matrix | string | Name of the Vertex Attribute Matrix for the new Vertex Data Container, if Create Vertex Geometry from Centroids is checked |
Required Geometry¶
Edge, Triangle, Quadrilateral, or Tetrahedral
Required Objects¶
None
Created Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Attribute Array | Centroids | float | (3) | Centroid coordinates of each Element in the supplied Geometry |
