Matt Juntunen commented on GEOMETRY7:

[~erans], this is done except for some additional javadocs that I need to add. I have two
general questions for you, though:
# I named the main classes PolarCoordinates and SphericalCoordinates but those seem kind
of verbose to me now. Should we shorten it to Polar/Spherical or PolarCoords/SphericalCoords?
# I pulled out the two methods dealing with Jacobian and Hessian matrices from the old
SphericalCoordinates class and put them in a new class named o.a.c.geometry.euclidean.threed.SphericalDerivativeConverter.
The math involved here is a bit over my head so I'm not sure if this is a good name for the
class or if the API is even useful. I really don't know what someone would use this for.

> Project: Apache Commons Geometry
> Issue Type: New Feature
> Reporter: Matt Juntunen

> Add support for Polar coordinates in Euclidean 2D space and Spherical coordinates in
Eucllidean 3D space. The coordinate classes should follow VALJO guidelines ([http://blog.joda.org/2014/03/valjosvaluejavaobjects.html]) and
be directly convertible to and from the corresponding Point/Vector types. The API should look
something like this:
>
> {code:java}
> Polar polar = Polar.of(1, Math.PI / 2);
> polar.getRadius(); // 1
> polar.getTheta(); // 2
> Vector2D vec = Vector2D.ofPolar(polar);
> // also possible: Vector2D.ofPolar(1, Math.PI / 2)
> // do stuff with vec
> Polar result = vec.getPolar();{code}
>
> For the Spherical component, the functionality should be merged with the existing o.a.c.geometry.spherical.SphericalCoordinates
class.
