Detailed Description

create a polygonal sphere centered at the origin

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.

virtual void vtkSphereSource::SetLatLongTessellation int   )  [virtual]
 

Cause the sphere to be tessellated with edges along the latitude and longitude lines. If off, triangles are generated at non-polar regions, which results in edges that are not parallel to latitude and 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.

Cause the sphere to be tessellated with edges along the latitude and longitude lines. If off, triangles are generated at non-polar regions, which results in edges that are not parallel to latitude and 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.

virtual void vtkSphereSource::LatLongTessellationOn  )  [virtual]
 

Cause the sphere to be tessellated with edges along the latitude and longitude lines.
