Detailed Description

template<typename T>
class Spline3D< T >

A class representing a quadratic 3D B-spline curve. It is templated: the parameter T is the type of the values it interpolates as well as the type of the parameter

Contstruct a set of splines representing the centerline described as a set of lines in *data. The algorithm will detect when centerlines split and make separate spline for the branch.

Parameters

data	A set of points with lines between them

Returns: a set of 3D splines

Definition at line 323 of file spline3d.hpp.

template<typename T>

void Spline3D< T >::compute ( )

inline

Initializes the underlying spline structure with the provided data. Needs to be called after adding points to the spline before evaluating it. If it isn't, it will be done automatically

void Spline3D< T >::derivativeSingle	(	T	t,
		T	point[3]
	)		const

inline

Get the derivative of the curve at position t

Parameters

t	The position to find the derivative for
point	The gradient vector at t=t

Definition at line 272 of file spline3d.hpp.

template<typename T>

void Spline3D< T >::evaluateSingle	(	T	t,
		T	point[3]
	)		const

inline

Evaluate the curve at position t

Parameters

t	the parameter position to evaluate at
point	The spatial position at parameter position t

template<typename T>

void Spline3D< T >::findAllIntersections ( const vector< MetaImage< inData_t > > & imgs )

inline

Find all intersections for a set of images. The result can be retrieved by getIntersections() and getConstIntersections

Parameters

imgs	Vector of images to intersect with the curve

Definition at line 516 of file spline3d.hpp.

template<typename T>

Intersection<T> Spline3D< T >::findIntersection ( const MetaImage< inData_t > * img ) const

inline

Find an intersection with a MetaImage

Parameters

img	The image to find an intersection with

Returns: Intersection instance where the image intersects with the curve. If no intersection was found, the isValid() method of the returned instance will return false.

template<typename T>

bool Spline3D< T >::intersect	(	T &	t,
		Plane3D &	plane,
		T	pointOnPlane[3]

inline

Find an intersection between this curve and a plane. The method is to first find two adjacent points in m_points (the points to interpolate) that is on different sides of the plane. Then we call findRoots() to find the exact location between those two points.

Parameters

t	The position to start at. Will contain the intersection position after
plane	The plane to intersect with
pointOnPlane	will contain a point that is both on the curve and on the plane.

Returns: true if an intersection was found, false otherwise.
