[jira] [Updated] (GEOMETRY-7) Add Support for Polar and Spherical
Coordinates
[ https://issues.apache.org/jira/browse/GEOMETRY-7?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Matt Juntunen updated GEOMETRY-7:
---------------------------------
Description:
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/valjos-value-java-objects.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.
