Class EllipseBounds¶

Defined in File EllipseBounds.hpp

Inheritance Relationships¶

Base Type¶

public Acts::PlanarBounds (Class PlanarBounds)

Class Documentation¶

class Acts::EllipseBounds : public Acts::PlanarBounds ¶

Class to describe the bounds for a planar ellispoid surface.

By providing an argument for hphisec, the bounds can be restricted to a phi-range around the center position.

Public Types

enum BoundValues¶

Values:

enumerator eInnerRx¶

enumerator eInnerRy¶

enumerator eOuterRx¶

enumerator eOuterRy¶

enumerator eHalfPhiSector¶

enumerator eAveragePhi¶

enumerator eSize¶

Public Functions

EllipseBounds() = delete¶

EllipseBounds(double innerRx, double innerRy, double outerRx, double outerRy, double halfPhi = M_PI, double averagePhi = 0.) noexcept(false)¶

Constructor for full of an ellipsoid ring.

Parameters

innerRx: The inner ellipse radius in x
innerRy: The inner ellipse radius in y
outerRx: The outer ellipse radius in x
outerRy: The outer ellipse radius in y
halfPhi: spanning phi sector (is set to pi as default)
averagePhi: average phi (is set to 0. as default)

EllipseBounds(const std::array<double, eSize> &values) noexcept(false)¶

Constructor - from fixed size array.

Parameters

values: The parameter values

~EllipseBounds() override = default¶

const RectangleBounds &boundingBox() const final¶

Bounding box parameters.

Return: rectangle bounds for a bounding box

double get(BoundValues bValue) const¶

Access to the bound values.

Parameters

bValue: the class nested enum for the array access

bool inside(const Vector2 &lposition, const BoundaryCheck &bcheck) const final¶

This method checks if the point given in the local coordinates is between two ellipsoids if only tol0 is given and additional in the phi sector is tol1 is given.

Return

boolean indicator for the success of this operation

Parameters

lposition: Local position (assumed to be in right surface frame)
bcheck: boundary check directive

std::ostream &toStream(std::ostream &sl) const final¶: Output Method for std::ostream.

BoundsType type() const final¶

Return the bounds type - for persistency optimization.

Return: is a BoundsType enum

std::vector<double> values() const final¶

Return the bound values as dynamically sized vector.

Return: this returns a copy of the internal values

std::vector<Vector2> vertices(unsigned int lseg) const final¶

Return the vertices.

Note

the number of segements to may be altered by also providing the extremas in all direction

Return

vector for vertices in 2D

Parameters

lseg: the number of segments used to approximate and eventually curved line, here it refers to the full 2PI Ellipse
