// .NAME vtkTexturedSphereSource - create a sphere centered at the origin
|
|
// .SECTION Description
|
|
// 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.
