Follow-up Comment #3, patch #8951 (project octave):
A few other comments:
* now I see you have facenormals for free as a by product of your algorithm
for computing vertexnormals. This is at least another good reason to switch to
ML compatible properties.
* I don't think Octave supports non planar patches, does Matlab do? If not
then your algorithm can be simplified for polygons: any three vertices are
enough to compute the normal for the entire face.
* In step 2, I see a comment about weighted average, based on adjacent faces
area, but can't find it afterwards. Shouldn't weighting be done in Step 1?
