Detailed Description

Define an N-dimensional ellipsoidal region of interest.

Intended use:

Public interface

Prerequisite

LCRegion

Synopsis

The LCEllipsoid class is a specialization of class LCRegion . It makes it possible to define an N-dimensional ellipsoidal region of interest, which includes the border. A separate constructor exists to define the special case of an N-dimensional sphere.
The center and the radii of the ellipsoid do not need to be pixel aligned. The center of the ellipsoid must be inside the lattice. The current implementation only supports ellipsoids with axes parallel to the lattice axes.

It can only be used for a lattice of any dimensionality as long as the dimensionality of the (hyper-)ellipsoid matches the dimensionality of the lattice.

Example

To Do

Arguments to have ellipsoid axes not parallel to lattice axes.

Constructor & Destructor Documentation

casa::LCEllipsoid::LCEllipsoid ( )

casa::LCEllipsoid::LCEllipsoid	(	const IPosition &	center,
		Float	radius,
		const IPosition &	latticeShape
	)

Construct an N-dimensional sphere with the given center and radius (in pixels).

The center is pixel-aligned.

casa::LCEllipsoid::LCEllipsoid	(	const Vector< Float > &	center,
		Float	radius,
		const IPosition &	latticeShape
	)

Construct an N-dimensional sphere with the given center and radius (in pixels).

The center does not need to be pixel-aligned.

casa::LCEllipsoid::LCEllipsoid	(	const Vector< Double > &	center,
		Double	radius,
		const IPosition &	latticeShape
	)

casa::LCEllipsoid::LCEllipsoid	(	const Vector< Float > &	center,
		const Vector< Float > &	radii,
		const IPosition &	latticeShape
	)

Construct an N-dimensional ellipsoid with the given center and radii (in pixels).

The center does not need to be pixel-aligned. (the radii are half the length of the axes of the ellipsoid).

casa::LCEllipsoid::LCEllipsoid	(	const Vector< Double > &	center,
		const Vector< Double > &	radii,
		const IPosition &	latticeShape
	)

casa::LCEllipsoid::LCEllipsoid ( const LCEllipsoid & other )

Copy constructor (reference semantics).

Member Function Documentation

const Vector< Float > & casa::LCEllipsoid::center ( ) const [inline]

Get the center.

Definition at line 165 of file LCEllipsoid.h.

References itsCenter.

static String casa::LCEllipsoid::className ( ) [static]

Get the class name (to store in the record).

virtual LCRegion* casa::LCEllipsoid::cloneRegion ( ) const [virtual]

Make a copy of the derived object.

Implements casa::LCRegion.

void casa::LCEllipsoid::defineMask ( ) [private]

Define the mask to indicate which elements are inside the ellipsoid.

virtual LCRegion* casa::LCEllipsoid::doTranslate	(	const Vector< Float > &	translateVector,
		const IPosition &	newLatticeShape
	)			const `[protected, virtual]`

Construct another LCBox (for e.g.

another lattice) by moving this one. It recalculates the bounding box. A positive translation value indicates "to right".

Implements casa::LCRegion.

void casa::LCEllipsoid::fillCenter ( const IPosition & center ) [private]

Fill the itsCenter vector from an IPosition.

static LCEllipsoid* casa::LCEllipsoid::fromRecord	(	const TableRecord &	,

	)			`[static]`

Convert correct object from a record.

Reimplemented from casa::LCRegion.
