Detailed Description

Create a polygonal lat-long grid.

This filter generates polydata to illustrate the distortions introduced by a map projection. The level parameter specifies the number of lines to be drawn. Poles are treated differently than other regions; hence the use of a Level parameter instead of a NumberOfLines parameter. The latitude and longitude are specified as half-open intervals with units of degrees. By default the latitude bounds are [-90,90[ and the longitude bounds are [0,180[.

Member Function Documentation

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

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkGeoGraticule::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 const char* vtkGeoGraticule::GetClassName ( ) [virtual]

Reimplemented from vtkPolyDataAlgorithm.

static int vtkGeoGraticule::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.

virtual int vtkGeoGraticule::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.

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

Reimplemented from vtkPolyDataAlgorithm.
