/**
* @class vtkSphericalTransform
* @brief spherical to rectangular coords and back
*
* vtkSphericalTransform will convert (r,phi,theta) coordinates to
* (x,y,z) coordinates and back again. The angles are given in radians.
* By default, it converts spherical coordinates to rectangular, but
* GetInverse() returns a transform that will do the opposite. The equation
* that is used is x = r*sin(phi)*cos(theta), y = r*sin(phi)*sin(theta),
* z = r*cos(phi).
* @warning
* This transform is not well behaved along the line x=y=0 (i.e. along
* the z-axis)
* @sa
* vtkCylindricalTransform vtkGeneralTransform
