FILT: Find Element Centroids

From the DREAM3D 6.6 version

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**:
