Detailed Description

Sphere patch with Lat/Long scalar array.

vtkGlobeSource will generate any "rectangular" patch of the globe given its Longitude-Latitude extent. It adds two point scalar arrays Longitude and Latitude to the output. These arrays can be transformed to generate texture coordinates for any texture map. This source is imperfect near the poles as implmented. It should really reduce the longitude resolution as the triangles become slivers.

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

Reimplemented from vtkPolyDataAlgorithm.

static int vtkGlobeSource::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkGlobeSource::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

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

Reimplemented from vtkPolyDataAlgorithm.

void vtkGlobeSource::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.

virtual void vtkGlobeSource::SetOrigin ( double  ,
double  ,
double   
) [virtual]

virtual void vtkGlobeSource::SetOrigin ( double  [3]  )  [virtual]

virtual void vtkGlobeSource::SetStartLongitude ( double   )  [virtual]

Longitude Latitude clamps.

virtual void vtkGlobeSource::SetEndLongitude ( double   )  [virtual]

Longitude Latitude clamps.

virtual void vtkGlobeSource::SetStartLatitude ( double   )  [virtual]

Longitude Latitude clamps.

virtual void vtkGlobeSource::SetEndLatitude ( double   )  [virtual]

Longitude Latitude clamps.

virtual void vtkGlobeSource::SetLongitudeResolution ( int   )  [virtual]

Set the number of points in the longitude direction (ranging from StartLongitude to EndLongitude).

virtual int vtkGlobeSource::GetLongitudeResolution (  )  [virtual]

Set the number of points in the longitude direction (ranging from StartLongitude to EndLongitude).

virtual void vtkGlobeSource::SetLatitudeResolution ( int   )  [virtual]

Set the number of points in the latitude direction (ranging from StartLatitude to EndLatitude).

virtual int vtkGlobeSource::GetLatitudeResolution (  )  [virtual]

Set the number of points in the latitude direction (ranging from StartLatitude to EndLatitude).

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

Set radius of sphere. Default is 6356750.0

virtual double vtkGlobeSource::GetRadius (  )  [virtual]

Set radius of sphere. Default is 6356750.0

virtual void vtkGlobeSource::SetCurtainHeight ( double   )  [virtual]

virtual double vtkGlobeSource::GetCurtainHeight (  )  [virtual]

virtual void vtkGlobeSource::SetQuadrilateralTessellation ( 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 vtkGlobeSource::GetQuadrilateralTessellation (  )  [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 vtkGlobeSource::QuadrilateralTessellationOn (  )  [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 vtkGlobeSource::QuadrilateralTessellationOff (  )  [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.

static vtkGlobeSource* vtkGlobeSource::New (  )  [static]

Construct sphere with radius=0.5 and default resolution 8 in both latitude and longitude directions. longitude ranges from (-180,180) and latitude (-90,90) degrees.

Reimplemented from vtkPolyDataAlgorithm.

static void vtkGlobeSource::ComputeGlobePoint ( double  theta,
double  phi,
double  radius,
double *  point,
double *  normal = 0

vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.

int vtkGlobeSource::RequestInformation ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
) [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.
