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 const char* vtkSphereSource::GetClassName ( ) [virtual]

Reimplemented from vtkPolyDataAlgorithm.

Reimplemented in vtkPSphereSource.

static int vtkSphereSource::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

Reimplemented in vtkPSphereSource.

virtual int vtkSphereSource::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

Reimplemented in vtkPSphereSource.

static vtkSphereSource* vtkSphereSource::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

Reimplemented in vtkPSphereSource.

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 vtkPolyDataAlgorithm.

Reimplemented in vtkPSphereSource.

static 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 vtkPolyDataAlgorithm.

Reimplemented in vtkPSphereSource.

virtual void vtkSphereSource::SetRadius ( double ) [virtual]

Set radius of sphere. Default is .5.

virtual double vtkSphereSource::GetRadius ( ) [virtual]

Set radius of sphere. Default is .5.

virtual void vtkSphereSource::SetCenter	(	double	,

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. 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::LatLongTessellationOff ( ) [virtual]

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