## Detailed Description

create a polygonal sphere centered at the origin

Date:
  2002/01/22 15:29:47

Revision:
  1.50

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.

Warning:
  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.

void vtkSphereSource::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

| Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkPolyDataSource. Reimplemented in vtkPSphereSource.

vtkSphereSource* vtkSphereSource::New | ( |  | ) | `[static]`

| Construct sphere with radius=0.5 and default resolution 8 in both Phi and Theta directions. Theta ranges from (0,360) and phi (0,180) degrees. Reimplemented from vtkObject. Reimplemented in vtkPSphereSource.
