Well, performance is not my first concern.
I just want encapsulated classes for convenience, that handle all
sorts of spherical coordinate specifics.
For instance... interpolation between spherical coordinates. You can avoid
going to/from cartesian if you properly handle the wrap-around at 180 and 360
degrees.
Also, I want to be able to recursively subdivide the theta,phy space, and
do stratification in theta,phy space, and al sorts of other operations, on
the surface of a given sphere.
An encapsulating class for these kind of coordinates would be a help, I
thought.
