Detailed Description

A transformation between long-lat-alt and rect coords.

the cartesian coordinate system is the following (if BaseAltitude is 0),

the origin is at the center of the earth
the x axis goes from the origin to (longtitude=-90,latitude=0), intersection of equator and the meridian passing just east of Galapagos Islands
the y axis goes from the origin to the intersection of Greenwitch meridian and equator (longitude=0,latitude=0)
the z axis goes from the origin to the Geographic North Pole (latitude=90)
therefore the frame is right-handed.

Member Function Documentation

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

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

Reimplemented from vtkObject.

virtual void vtkGeoSphereTransform::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 vtkAbstractTransform.

static int vtkGeoSphereTransform::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 vtkAbstractTransform.

virtual int vtkGeoSphereTransform::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 vtkAbstractTransform.

static vtkGeoSphereTransform* vtkGeoSphereTransform::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkAbstractTransform.

virtual vtkObjectBase* vtkGeoSphereTransform::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkAbstractTransform.

vtkGeoSphereTransform* vtkGeoSphereTransform::NewInstance ( ) const

Reimplemented from vtkAbstractTransform.

virtual void vtkGeoSphereTransform::Inverse ( ) [virtual]

Invert the transformation.

Implements vtkAbstractTransform.

virtual void vtkGeoSphereTransform::InternalTransformPoint	(	const float	in[3],
		float	out[3]
	)		`[virtual]`

This will calculate the transformation without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

virtual void vtkGeoSphereTransform::InternalTransformPoint	(	const double	in[3],
		double	out[3]
	)		`[virtual]`

This will calculate the transformation without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

virtual void vtkGeoSphereTransform::InternalTransformDerivative	(	const float	in[3],
		float	out[3],
		float	derivative[3][3]
	)		`[virtual]`

This will transform a point and, at the same time, calculate a 3x3 Jacobian matrix that provides the partial derivatives of the transformation at that point. This method does not call Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

virtual void vtkGeoSphereTransform::InternalTransformDerivative	(	const double	in[3],
		double	out[3],
		double	derivative[3][3]
	)		`[virtual]`

This will transform a point and, at the same time, calculate a 3x3 Jacobian matrix that provides the partial derivatives of the transformation at that point. This method does not call Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

virtual vtkAbstractTransform* vtkGeoSphereTransform::MakeTransform ( ) [virtual]

Make another transform of the same type.

Implements vtkAbstractTransform.

virtual void vtkGeoSphereTransform::SetToRectangular ( bool ) [virtual]

If on, this transform converts (long,lat,alt) triples to (x,y,z) as an offset from the center of the earth. Alt, x, y, and z are all be in meters. If off, the transform works in the reverse direction. Initial value is on.

virtual bool vtkGeoSphereTransform::GetToRectangular ( ) [virtual]

If on, this transform converts (long,lat,alt) triples to (x,y,z) as an offset from the center of the earth. Alt, x, y, and z are all be in meters. If off, the transform works in the reverse direction. Initial value is on.

virtual void vtkGeoSphereTransform::ToRectangularOn ( ) [virtual]

If on, this transform converts (long,lat,alt) triples to (x,y,z) as an offset from the center of the earth. Alt, x, y, and z are all be in meters. If off, the transform works in the reverse direction. Initial value is on.

virtual void vtkGeoSphereTransform::ToRectangularOff ( ) [virtual]

If on, this transform converts (long,lat,alt) triples to (x,y,z) as an offset from the center of the earth. Alt, x, y, and z are all be in meters. If off, the transform works in the reverse direction. Initial value is on.

virtual void vtkGeoSphereTransform::SetBaseAltitude ( double ) [virtual]

The base altitude to transform coordinates to. This can be useful for transforming lines just above the earth's surface. Default is 0.

virtual double vtkGeoSphereTransform::GetBaseAltitude ( ) [virtual]

The base altitude to transform coordinates to. This can be useful for transforming lines just above the earth's surface. Default is 0.
