// .NAME vtkSphericalDirectionEncoder - A direction encoder based on spherical coordinates
// .SECTION Description
// vtkSphericalDirectionEncoder is a direction encoder which uses spherical
// coordinates for mapping (nx, ny, nz) into an azimuth, elevation pair.
//
// .SECTION see also
// vtkDirectionEncoder
