// .NAME vtkSphereSource - create a polygonal sphere centered at the origin
// .SECTION Description
// vtkSphereSource creates a sphere (represented by polygons) of specified
// radius centered at the origin. The resolution (polygonal discretization)
// in both the latitude (phi) and longitude (theta) directions can be
// specified. It also is possible to create partial spheres by specifying
// maximum phi and theta angles. By default, the surface tessellation of
// the sphere uses triangles; however you can set LatLongTessellation to
// produce a tessellation using quadrilaterals.
// .SECTION Caveats
// Resolution means the number of latitude or longitude lines for a complete
// sphere. If you create partial spheres the number of latitude/longitude
// lines may be off by one.

// Cause the sphere to be tessellated with edges along the latitude

// longitude lines. If on, quadrilaterals are generated everywhere
// except at the poles. This can be useful for generating a wireframe
// sphere with natural latitude and longitude lines.
