Can I get face centroid for a particular polygon from MFnMesh information?

MFnMesh meshFn(fMesh);
meshFn.getPolygonNormal(....) gives the normal for the particular polygon.

My question is how can I obtain the centroid for each polygon from MFnMesh data?

Hi,

Look instead at the class method: MItMeshPolygon.center()
This will require you to iterate through the polys on your mesh, but there is not method for getting the centre of a specific polygon.

I did write this a while back - it’s plain ol’ python, but it may help:

Hi,

Try looking instead at MItMeshPolygon.center()
This iterates over your mesh and is not exactly what you want, but I don’t think there is a method for querying the centre of a specific face.

If you can live with plain ol’ python, I did write this a while back:
