Constructor & Destructor Documentation

imaging::Circle::Circle	(	const ublas::fixed_vector< float_t, 2 > &	center,
		float_t	radius
	)			[inline]

Construct a circle from center and radius.

imaging::Circle::Circle

(

const Circle &

source

)

[inline]

Copy constructor.

Member Function Documentation

const Circle & imaging::Circle::operator=

(

const Circle &

source

)

Copy assignement.

std::auto_ptr< BoundaryDiscretizer< 2 > > imaging::Circle::boundary_discretizer

(

size_t

n_points

)

const [virtual]

Returns a boundary discretizer for this shape.

Implements imaging::DiscretizableShapeInterface< 2 >.

void imaging::Circle::set_center

(

const ublas::fixed_vector< float_t, 2 > &

center

)

Sets the center of the circle.

void imaging::Circle::set_radius

(

float_t

radius

)

Sets the radius of the circle.

const ublas::fixed_vector<float_t, 2>& imaging::Circle::center

(

)

const [inline]

Returns the center.

float_t imaging::Circle::radius

(

)

const [inline]

Returns the radius.

void imaging::Circle::exponential	(	const ublas::vector< float_t > &	vector,
		ShapeInterface &	shape
	)			const [virtual]

Computes the Riemannian exponential of vector with respect to *this and stores the result in shape. In other words, shape is the projection of the tangent vector vector in the tangent space at the *this shape on the shape manifold.

Implements imaging::ShapeInterface.

References _center, and _radius.

void imaging::Circle::logarithm	(	const ShapeInterface &	shape,
		ublas::vector< float_t > &	vector
	)			const [virtual]

Computes the Riemannian logarithm of shape with respect to *this and stores the result in vector. In other words, vector is the projection of shape on the tangent space at the *this shape on the shape manifold.

Implements imaging::ShapeInterface.

References _center, and _radius.

size_t imaging::Circle::dimension

(

)

const [inline, virtual]

Returns the parametric dimension of the shape object. This is the same as the dimension of the shape manifold the shape belongs to. It should not be confused with the spatial dimension N.

Implements imaging::ShapeInterface.

---

Member Data Documentation

const size_t imaging::Circle::SHAPE_DIMENSION = 2 [static]

The spatial dimension of the shape class. N is 2 for planar shapes and 3 for volumes.

Reimplemented from imaging::DiscretizableShapeInterface< 2 >.
