Constructor & Destructor Documentation

Default constructor, deleted.

Defaulted destructor.

Acts::ConvexPolygonBounds< PolygonDynamic >::ConvexPolygonBounds ( const std::vector< Vector2D > &  vertices)

Constructor from a vector of vertices, to facilitate construction. This will throw if the vertices do not form a convex polygon.

Parameters
verticesThe list of vertices.

Member Function Documentation

const RectangleBounds& Acts::ConvexPolygonBounds< PolygonDynamic >::boundingBox ( ) const
finalvirtual

Return a rectangle bounds object that encloses this polygon.

Returns
The rectangular bounds

Implements Acts::PlanarBounds.

void Acts::ConvexPolygonBounds< PolygonDynamic >::checkConsistency ( ) const
privatenoexcept

Return whether this bounds class is in fact convex thorws a logic error if not

double Acts::ConvexPolygonBounds< PolygonDynamic >::distanceToBoundary ( const Vector2D lposition) const
finalvirtual

Return the smallest distance to any point on the boundary of this bounds object.

Parameters
lposThe lposition position to get the distance to
Returns
The smallest distance to the boundary.

Implements Acts::SurfaceBounds.

bool Acts::ConvexPolygonBounds< PolygonDynamic >::inside ( const Vector2D lposition,
const BoundaryCheck bcheck 
) const
finalvirtual

Return whether a local 2D point lies inside of the bounds defined by this object.

Parameters
lpositionThe local position to check
bcheckThe BoundaryCheck object handling tolerances.
Returns
Whether the points is inside

Implements Acts::SurfaceBounds.

BoundsType Acts::ConvexPolygonBounds< PolygonDynamic >::type ( ) const
finalvirtual

Return the bounds type of this bounds object.

Returns
The bounds type

Implements Acts::SurfaceBounds.

std::vector<Vector2D> Acts::ConvexPolygonBounds< PolygonDynamic >::vertices ( unsigned int  lseg = 1) const
finalvirtual

Return the vertices

Parameters
lsegthe number of segments used to approximate and eventually curved line
Note
the number of segements is ignored in this representation
Returns
vector for vertices in 2D

Implements Acts::PlanarBounds.
