Detailed Description

template<size_t kDIM = 2u, size_t bSize = 100u, typename reference_generator = detail::PolyhedronReferenceGenerator<1u, false>>
class Acts::Experimental::KdtSurfaces< kDIM, bSize, reference_generator >

A wrapper class around a KDTree of surfaces.

It also deals with the conversion from global query to KDTree lookup positions

		const reference_generator &	rgen = `detail::PolyhedronReferenceGenerator<1u, false>{}`
	)

inline

surfaces	the surfaces to be filled into the tree
casts	the cast list from global position into kdtree local
rgen	the reference point generator

template<size_t kDIM = 2u, size_t bSize = 100u, typename reference_generator = detail::PolyhedronReferenceGenerator<1u, false>>

Query Acts::Experimental::KdtSurfaces< kDIM, bSize, reference_generator >::cog ( const std::vector< Query > & cQueries ) const

inlineprivate

Helper method to calculate the center of gravity in the casted frame (i.e. query frame)

Parameters

cQueries are the casted query positions

Note: will do nothing if vector size is equal to 1; no checking on qQueries.empty() is done as the positions are to be provided by a generator which itself is tested for consistency

Returns: the center of gravity as a query object
