class Acts::TrapezoidVolumeBounds : public Acts::VolumeBounds

Bounds for a trapezoidal shaped Volume, the orientedSurface(…) method creates a vector of 6 surfaces:

BoundarySurfaceFace [index]:

  • negativeFaceXY [0] : Trazpezoidal Acts::PlaneSurface, parallel to \( xy \) plane at negative \(z\)

  • positiveFaceXY [1] : Trazpezoidal Acts::PlaneSurface, parallel to \( xy \) plane at positive \(z\)

  • trapezoidFaceAlpha [2] : Rectangular Acts::PlaneSurface, attached to [0] and [1] at negative \(x\) (associated to alpha)

  • trapezoidFaceBeta [3] : Rectangular Acts::PlaneSurface, attached to [0] and [1] at positive \( x\) (associated to beta)

  • negativeFaceZX [4] : Rectangular Acts::PlaneSurface, parallel to \( zx \) plane at negative \(y\)

  • positiveFaceZX [5] : Rectangular Acts::PlaneSurface, parallel to \( zx \) plane at positive \(y\)

Public Functions

TrapezoidVolumeBounds() = delete
TrapezoidVolumeBounds(double minhalex, double maxhalex, double haley, double halez) noexcept(false)

Constructor - the trapezoid boundaries (symmetric trapezoid)

Parameters

  • minhalex: is the half length in x at minimal y

  • maxhalex: is the half length in x at maximal y

  • haley: is the half length in y

  • halez: is the half length in z

TrapezoidVolumeBounds(double minhalex, double haley, double halez, double alpha, double beta) noexcept(false)

Constructor - the trapezoid boundaries (arbitrary trapezoid)

Parameters

  • minhalex: is the half length in x at minimal y

  • haley: is the half length in y

  • halez: is the half length in z

  • alpha: is the openeing angle at -x,-y

  • beta: is the openeing angle at +x,-y

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

Constructor - from a fixed size array.

Parameters

  • values: The bound values

TrapezoidVolumeBounds(const TrapezoidVolumeBounds &trabo) = default
~TrapezoidVolumeBounds() override = default
Volume::BoundingBox boundingBox(const Transform3 *trf = nullptr, const Vector3 &envelope = {0, 0, 0}, const Volume *entity = nullptr) const final

Construct bounding box for this shape.

Return

Constructed bounding box

Parameters

  • trf: Optional transform

  • envelope: Optional envelope to add / subtract from min/max

  • entity: Entity to associate this bounding box with

double get(BoundValues bValue) const

Access to the bound values.

Parameters

  • bValue: the class nested enum for the array access

bool inside(const Vector3 &pos, double tol = 0.) const override

This method checks if position in the 3D volume frame is inside the cylinder.

Return

boolean indicator if position is inside

Parameters

  • pos: is the global position to be checked

  • tol: is the tolerance applied

TrapezoidVolumeBounds &operator=(const TrapezoidVolumeBounds &trabo) = default
OrientedSurfaces orientedSurfaces(const Transform3 &transform = Transform3::Identity()) const override

Oriented surfaces, i.e.

the decomposed boundary surfaces and the according navigation direction into the volume given the normal vector on the surface

It will throw an exception if the orientation prescription is not adequate

Parameters

  • transform: is the 3D transform to be applied to the boundary surfaces to position them in 3D space

Return

a vector of surfaces bounding this volume

std::ostream &toStream(std::ostream &sl) const override

Output Method for std::ostream.

VolumeBounds::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
