std::array< double, dim > GeometricUtilities::Coordinates::to_spherical | ( | const Point< dim > & | point | ) |
Return spherical coordinates of a Cartesian point point
. The returned array is filled with radius, azimuth angle
In 3d the transformation is given by
The use of this function is demonstrated in step-75.
