Detailed Description

Volume bounds described by eight arbitrary cuboid vertices.

Constructor & Destructor Documentation

GenericCuboidVolumeBounds() [1/2]

Acts::GenericCuboidVolumeBounds::GenericCuboidVolumeBounds ( const std::array< Acts::Vector3, 8 > & vertices )

explicit

Constructor from a set of vertices.

Parameters

vertices

The set of input vertices

The ordering is considered to be:

• the first 4 vertices are the "top" face
• the second 4 vertices are the "bottom" face
• both faces are given in counter clock wise order

GenericCuboidVolumeBounds() [2/2]

Acts::GenericCuboidVolumeBounds::GenericCuboidVolumeBounds ( const std::array< double, BoundValues::eSize > & values )

explicit

Constructor from a fixed size array.

Parameters

values

The input values

Member Function Documentation

boundingBox()

Volume::BoundingBox Acts::GenericCuboidVolumeBounds::boundingBox ( const Transform3 * trf = nullptr, const Vector3 & envelope = {0, 0, 0}, const Volume * entity = nullptr ) const

finalvirtual

Construct bounding box for this shape.

Parameters

trf	Optional transform
envelope	Optional envelope to add / subtract from min/max
entity	Entity to associate this bounding box with

Returns

Constructed bounding box

Implements Acts::VolumeBounds.

canonicalAxes()

std::vector< AxisDirection > Acts::GenericCuboidVolumeBounds::canonicalAxes ( ) const

overridevirtual

Get the canonical direction values, i.e.

the axis directions that fully describe the shape's extent

Returns

vector of canonical binning values

Reimplemented from Acts::VolumeBounds.

draw()

void Acts::GenericCuboidVolumeBounds::draw	(	IVisualization3D &	helper,
		const Transform3 &	transform = Transform3::Identity() ) const

Draw this shape using a visualization helper.

Parameters

helper	The visualizatin helper
transform	Optional transformation matrix

inside()

bool Acts::GenericCuboidVolumeBounds::inside ( const Vector3 & gpos, double tol = 0. ) const

overridevirtual

Checking if position given in volume frame is inside.

Parameters

gpos	is the global position to be checked
tol	is the tolerance applied for the inside check

Returns

boolean indicating if the position is inside

Implements Acts::VolumeBounds.

orientedSurfaces()

std::vector< OrientedSurface > Acts::GenericCuboidVolumeBounds::orientedSurfaces ( const Transform3 & transform = Transform3::Identity() ) const

overridevirtual

Oriented surfaces, i.e.

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

Parameters

transform

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

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

Returns

a vector of surfaces bounding this volume

Implements Acts::VolumeBounds.

toStream()

std::ostream & Acts::GenericCuboidVolumeBounds::toStream ( std::ostream & sl ) const

overridevirtual

Parameters

sl	is the output stream to be written into

Returns

The output stream

Implements Acts::VolumeBounds.

type()

VolumeBounds::BoundsType Acts::GenericCuboidVolumeBounds::type ( ) const

finalvirtual

Return the bounds type - for persistency optimization.

Returns

is a BoundsType enum

Implements Acts::VolumeBounds.

values()

std::vector< double > Acts::GenericCuboidVolumeBounds::values ( ) const

finalvirtual

Return the bound values as dynamically sized vector.

Returns

this returns a copy of the internal values

Implements Acts::VolumeBounds.
