Detailed Description

create a polygonal sphere centered at the origin.

Date:

2001/10/11 13:37:16

Revision:

1.48

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.

Member Function Documentation

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. Reimplemented in vtkPSphereSource.

int vtkSphereSource::IsTypeOf (  const char *    type )  [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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. Reimplemented in vtkPSphereSource.

virtual int vtkSphereSource::IsA (  const char *    type )  [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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. Reimplemented in vtkPSphereSource.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. 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 vtkSource.

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 vtkPolyDataSource. Reimplemented in vtkPSphereSource.

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

Set radius of sphere. Default is .5.

virtual float vtkSphereSource::GetRadius (    )  [virtual]

Set radius of sphere. Default is .5.

virtual void vtkSphereSource::SetCenter (  float   , float   , float    )  [virtual]

Set the center of the sphere. Default is 0,0,0.

virtual void vtkSphereSource::SetCenter (  float   [3] )  [virtual]

Set the center of the sphere. Default is 0,0,0.

virtual float* vtkSphereSource::GetCenter (    )  [virtual]

Set the center of the sphere. Default is 0,0,0.

virtual void vtkSphereSource::GetCenter (  float    data[3] )  [virtual]

Set the center of the sphere. Default is 0,0,0.

virtual void vtkSphereSource::SetThetaResolution (  int    )  [virtual]

Set the number of points in the longitude direction (ranging from StartTheta to EndTheta).

virtual int vtkSphereSource::GetThetaResolution (    )  [virtual]

Set the number of points in the longitude direction (ranging from StartTheta to EndTheta).

virtual void vtkSphereSource::SetPhiResolution (  int    )  [virtual]

Set the number of points in the latitude direction (ranging from StartPhi to EndPhi).

virtual int vtkSphereSource::GetPhiResolution (    )  [virtual]

Set the number of points in the latitude direction (ranging from StartPhi to EndPhi).

virtual void vtkSphereSource::SetStartTheta (  float    )  [virtual]

Set the starting longitude angle. By default StartTheta=0 degrees.

virtual float vtkSphereSource::GetStartTheta (    )  [virtual]

Set the starting longitude angle. By default StartTheta=0 degrees.

virtual void vtkSphereSource::SetEndTheta (  float    )  [virtual]

Set the ending longitude angle. By default EndTheta=360 degrees.

virtual float vtkSphereSource::GetEndTheta (    )  [virtual]

Set the ending longitude angle. By default EndTheta=360 degrees.

virtual void vtkSphereSource::SetStartPhi (  float    )  [virtual]

Set the starting latitude angle (0 is at north pole). By default StartPhi=0 degrees.

virtual float vtkSphereSource::GetStartPhi (    )  [virtual]

Set the starting latitude angle (0 is at north pole). By default StartPhi=0 degrees.

virtual void vtkSphereSource::SetEndPhi (  float    )  [virtual]

Set the ending latitude angle. By default EndPhi=180 degrees.

virtual float vtkSphereSource::GetEndPhi (    )  [virtual]

Set the ending latitude angle. By default EndPhi=180 degrees.

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.

virtual int vtkSphereSource::GetLatLongTessellation (    )  [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::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. 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.

void vtkSphereSource::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource. Reimplemented in vtkPSphereSource.

void vtkSphereSource::ExecuteInformation (    )  [protected, virtual]

Reimplemented from vtkSource.
