Constructor & Destructor Documentation

ellipsoid::ellipsoid

(

)

[inline]

Default constructor that assigns radius 0 to the ellipsoid

ellipsoid::ellipsoid	(	vector3	C,
		vector3	a0,
		vector3	a1,
		vector3	a2,
		double	_r0,
		double	_r1,
		double	_r2
	)			[inline]

Parameters:

[in]	C	The 3D point corresponding to the center of the ellipsoid.
[in]	a0	The 3D vector corresponding to the first principal axis of the ellipsoid.
[in]	a1	The 3D vector corresponding to the second principal axis of the ellipsoid.
[in]	a2	The 3D vector corresponding to the third principal axis of the ellipsoid.
[in]	_r0	The length of the first principal axis.
[in]	_r1	The length of the first principal axis.
[in]	_r2	The length of the first principal axis.

Initialises the parameters of an ellipsoid. Useful when the ellipsoid has been created using the default constructor.

Parameters:

[in]	C	The 3D point corresponding to the center of the ellipsoid.
[in]	a0	The 3D vector corresponding to the first principal axis of the ellipsoid.
[in]	a1	The 3D vector corresponding to the second principal axis of the ellipsoid.
[in]	a2	The 3D vector corresponding to the third principal axis of the ellipsoid.
[in]	_r0	The length of the first principal axis.
[in]	_r1	The length of the first principal axis.
[in]	_r2	The length of the first principal axis.

void ellipsoid::project_point	(	const vector3 &	input,
		vector3 &	output,
		ELLIPSOID_PROJECTION_TYPE	proj_type = MAHALANOBIS
	)			const [inline]

Project a point onto the ellipsoid.

Parameters:

[in]	input	The point to be projected.
[out]	output	The result of the projection.
[in]	proj_type	The choice of projection type.

void ellipsoid::project_point	(	const vector3 &	input,
		vector3 &	output,
		double &	N,
		ELLIPSOID_PROJECTION_TYPE	proj_type = MAHALANOBIS
	)			const [inline]

Project a point onto the ellipsoid.

Parameters:

[in]	input	The point to be projected.
[out]	output	The result of the projection.
[out]	N
[in]	proj_type	The choice of projection type.
