Member Function Documentation

boundToCartesianJacobian()

SquareMatrix2 Acts::InfiniteBounds::boundToCartesianJacobian ( const Vector2 & lposition ) const

finalvirtual

Computes the bound to cartesian jacobian at a given local position.

Parameters

lposition

is the local position at which the jacobian is computed

Returns

the bound to cartesian jacobian

Implements Acts::SurfaceBounds.

boundToCartesianMetric()

SquareMatrix2 Acts::InfiniteBounds::boundToCartesianMetric ( const Vector2 & lposition ) const

finalvirtual

Computes the bound to cartesian metric at a given local position.

Parameters

lposition

is the local position at which the metric is computed

Returns

the bound to cartesian metric

Implements Acts::SurfaceBounds.

center()

Vector2 Acts::InfiniteBounds::center ( ) const

finalvirtual

Calculate the center of the surface bounds in local coordinates.

This method returns a representative center point of the bounds region. The exact definition varies by bounds type and coordinate system:

Cartesian bounds (Rectangle, Diamond, Trapezoid):

• Returns the geometric center or center of symmetry
• For symmetric shapes: center of bounding box or origin (0,0)

Polar/Cylindrical bounds (Radial, Cylinder, Cone):

• Returns (r, phi) where r is average radius, phi is average angle
• Coordinates are in the bounds' natural coordinate system

Complex bounds (Annulus, ConvexPolygon):

• Annulus: Pre-calculated from corner vertices (accounts for coordinate transforms)
• Polygon: Average of all vertices (vertex centroid, not area centroid)

Infinite bounds: Returns conceptual center at (0,0)

Note

The returned point is guaranteed to be a reasonable representative center, but may not be the true geometric centroid for all shapes.

Returns

Vector2 representing the center position in local coordinates

Implements Acts::SurfaceBounds.

closestPoint()

Vector2 Acts::InfiniteBounds::closestPoint ( const Vector2 & lposition, const SquareMatrix2 & metric ) const

finalvirtual

Calculates the closest point on the bounds to a given local position.

Parameters

lposition	is the local position
metric	to be used for the distance calculation

Returns

the closest point on the bounds

Implements Acts::SurfaceBounds.

inside() [1/2]

bool Acts::InfiniteBounds::inside ( const Vector2 & lposition ) const

finalvirtual

Inside check for the bounds object.

Parameters

lposition

is the local position

Returns

true if the local position is inside the bounds

Implements Acts::SurfaceBounds.

inside() [2/2]

bool Acts::InfiniteBounds::inside ( const Vector2 & lposition, const BoundaryTolerance & boundaryTolerance ) const

finalvirtual

Inside check for the bounds object given a boundary tolerance.

Parameters

lposition	is the local position
boundaryTolerance	is the boundary tolerance object

Returns

true if the local position is inside the bounds and tolerance

Reimplemented from Acts::SurfaceBounds.

isCartesian()

bool Acts::InfiniteBounds::isCartesian ( ) const

finalvirtual

Check if the bound coordinates are cartesian.

Returns

true if the bound coordinates are cartesian

Implements Acts::SurfaceBounds.

toStream()

std::ostream & Acts::InfiniteBounds::toStream ( std::ostream & os ) const

finalvirtual

Output Method for std::ostream.

Parameters

os	Output stream to write to

Returns

Reference to the output stream for method chaining

Implements Acts::SurfaceBounds.

type()

SurfaceBounds::BoundsType Acts::InfiniteBounds::type ( ) const

finalvirtual

Return the bounds type - for persistency optimization.

Returns

the bounds type

Implements Acts::SurfaceBounds.

values()

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

finalvirtual

Access method for bound values, this is a dynamically sized vector containing the parameters needed to describe these bounds.

Returns

of the stored values for this SurfaceBounds object

Implements Acts::SurfaceBounds.
