* @class vtkTexturedSphereSource
* @brief create a sphere centered at the origin
*
* vtkTexturedSphereSource creates a polygonal sphere 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 sphere by specifying maximum phi and
* theta angles.
