class Acts::CutoutCylinderVolumeBounds : public Acts::VolumeBounds

Class which implements a cutout cylinder.

This shape is bascially a cylinder, with another, smaller cylinder subtracted from the center. —————— rmax | | | |——| | rmed | | | | — — rmin hlZc —— hlZ —-

Public Functions

CutoutCylinderVolumeBounds() = delete
CutoutCylinderVolumeBounds(double rmin, double rmed, double rmax, double hlZ, double hlZc) noexcept(false)

Constructor from defining parameters.

Parameters

  • rmin: Minimum radius at the “choke points”

  • rmed: The medium radius (outer radius of the cutout)

  • rmax: The outer radius of the overall shape

  • hlZ: The longer halflength of the shape

  • hlZc: The cutout halflength of the shape

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

Constructor - from a fixed size array.

Parameters

  • values: The bound values

~CutoutCylinderVolumeBounds() 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 &gpos, double tol = 0) const override

Inside method to test whether a point is inside the shape.

Return

Whether the point is inside or not.

Parameters

  • gpos: The point to test

  • tol: The tolerance to test with

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

Write information about this instance to an outstream.

Return

The outstream

Parameters

  • sl: The outstream

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
