Find Feature Centroids from Triangle Geometry

Group (Subgroup)

Statistics (Morphological)

Description

This Filter determines the centroids of each Feature in a Triangle Geometry. The centroids are determined using the following algorithm:

  1. Query each triangle within the Triangle Geometry to determine its two owners
  2. Add the 3 nodes of that triangle to the set of nodes bounding those two owners (Note that a set will only allow each node to be entered once for a given owner)
  3. For each Feature, find the average (x,y,z) coordinate from the set of nodes that bound it

Parameters

None

Required Geometry
