Q3Point3D_ToSpherical

You can use the Q3Point3D_ToSpherical function to convert a three-dimensional point from Cartesian form to spherical form.

TQ3SphericalPoint *Q3Point3D_ToSpherical (
const TQ3Point3D *point3D, 
TQ3SphericalPoint *result);

point3D

A three-dimensional point.

result

On exit, a spherical point.

DESCRIPTION

The Q3Point3D_ToSpherical function returns, as its function result and in the result parameter, a spherical point that is the same point as the three-dimensional point specified by the point3D parameter.
