Member Function Documentation

static vtkGeoMath* vtkGeoMath::New

(

)

[static]

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

Reimplemented from vtkObject.

virtual const char* vtkGeoMath::GetClassName

(

)

[virtual]

Reimplemented from vtkObject.

static int vtkGeoMath::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 vtkObject.

virtual int vtkGeoMath::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 vtkObject.

static vtkGeoMath* vtkGeoMath::SafeDownCast

(

vtkObject *

o

)

[static]

Reimplemented from vtkObject.

void vtkGeoMath::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 vtkObject.

static double vtkGeoMath::EarthRadiusMeters

(

)

[inline, static]

Returns the average radius of the earth in meters.

Definition at line 40 of file vtkGeoMath.h.

static double vtkGeoMath::DistanceSquared	(	double	pt0[3],
		double	pt1[3]
	)		[static]

Returns the squared distance between two points.

static void vtkGeoMath::LongLatAltToRect	(	double	lla[3],
		double	rect[3]
	)		[static]

Converts a (longitude, latitude, altitude) triple to world coordinates where the center of the earth is at the origin. Units are in meters. Note that having altitude realtive to sea level causes issues.
