This function converts a Euclidean coordinate to a spherical coordinate.

1	Trans.sph(vec)

vec

three-dimensional Euclidean coordinate.

This function converts a three-dimensional Euclidean coordinate to a two-dimensional spherical coordinate. If vec is not in the unit sphere, it is divided by its magnitude so that the result lies on the unit sphere.

two-dimensional vector.
