Include dependency graph for DoubleHitSpacePointBuilder.ipp:

This graph shows which files directly or indirectly include this file:

Classes
struct	Acts::detail::SpacePointParameters
	Storage container for variables related to the calculation of space points. More...

Namespaces
namespace	Acts
	Set the Geometry Context PLUGIN.

namespace	Acts::detail
	These functions perform the transport of a covariance matrix using given Jacobians. The required data is provided by the stepper object with some additional data. Since this is a purely algebraic problem the calculations are identical for `StraightLineStepper` and `EigenStepper`. As a consequence the methods can be located in a seperate file.

Functions
double	Acts::detail::differenceOfClustersChecked (const Vector3D &pos1, const Vector3D &pos2, const Vector3D &posVertex, const double maxDistance, const double maxAngleTheta2, const double maxAnglePhi2)
	Calculates (Delta theta)^2 + (Delta phi)^2 between two clusters.

std::pair< Vector2D, Vector2D >	Acts::detail::findLocalTopAndBottomEnd (const Vector2D &local, const CartesianSegmentation *segment)
	This function finds the top and bottom end of a detector segment in local coordinates.

double	Acts::detail::calcPerpendicularProjection (const Vector3D &a, const Vector3D &c, const Vector3D &q, const Vector3D &r)
	Calculates a space point whithout using the vertex.

bool	Acts::detail::recoverSpacePoint (SpacePointParameters &spaPoPa, double stripLengthGapTolerance)
	This function tests if a space point can be estimated by a more tolerant treatment of construction. In fact, this function indirectly allows shifts of the vertex.

bool	Acts::detail::calculateSpacePoint (const std::pair< Vector3D, Vector3D > &stripEnds1, const std::pair< Vector3D, Vector3D > &stripEnds2, const Vector3D &posVertex, SpacePointParameters &spaPoPa, const double stripLengthTolerance)
	This function performs a straight forward calculation of a space point and returns whether it was succesful or not.
