Member Function Documentation

template<typename coll_t >

void Acts::ConvexPolygonBoundsBase::convex_impl ( const coll_t &  vertices )

staticprotectednoexcept

Calculates whether a set of vertices forms a convex polygon. This is generic over the number of vertices, so it's factored out of the concrete classes and into this base class.

Parameters

vertices

A collection of vertices. throws a logic error if this is not the case

Acts::RectangleBounds Acts::ConvexPolygonBoundsBase::makeBoundingBox ( const coll_t &  vertices )

staticprotected

Return a rectangle bounds instance that encloses a set of vertices.

Parameters

vertices

A collection of vertices to enclose.

Returns

Enclosing rectangle.
