// .NAME vtkSphericalTransform - spherical to rectangular coords and back
// .SECTION Description
// 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).
// .SECTION Caveats
// This transform is not well behaved along the line x=y=0 (i.e. along
// the z-axis)
// .SECTION see also
// vtkCylindricalTransform vtkGeneralTransform
