The various centroids
- Point center of mass
- All vertices (including unreferenced vertices) are assumed to have equal mass and the center of mass is calculated.
- Face center of mass
- All polygons are assumed to have equal areal mass density and the center of mass is calculated.
- Volume center of mass
- The volume enclosed by the polygons is assumed to have uniform mass density and the center of mass is calculated. Note that if the mesh is not closed this is a poorly defined quantity.
