Dimitrios Efthymiou commented on GEOMETRY-160:
----------------------------------------------
[~erans] You ask: "how one can determine what belongs in the API within a given
scope"?
What is the scope of commons-geometry? Why is the method Vectors::normSq
even necessary when you can just do x*x - which was the argument someone
gave me for another convenience method I suggested 1/2 days ago?
It seems that the scope of this project does not include convenience methods.
Also, commons math is object-oriented and every aspect of math,
has a dedicated class that handles that math aspect. Why don't we do the same
for commons-geometry?
Thank you
