Detailed Description

template<std::size_t kDIM = 2u, std::size_t bSize = 100u>
class Acts::KdtSurfaces< kDIM, bSize >

A wrapper class around a KDTree of surfaces.

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

Member Typedef Documentation

Entry

template<std::size_t kDIM = 2u, std::size_t bSize = 100u>

using Acts::KdtSurfaces< kDIM, bSize >::Entry = std::pair<Query, std::shared_ptr<Surface>>

Broadcast the entry.

KDTS

template<std::size_t kDIM = 2u, std::size_t bSize = 100u>

using Acts::KdtSurfaces< kDIM, bSize >::KDTS

Initial value:

 
      KDTree<kDIM, std::shared_ptr<Surface>, double, std::array, bSize>

Broadcast the surface KDT type.

Query

template<std::size_t kDIM = 2u, std::size_t bSize = 100u>

using Acts::KdtSurfaces< kDIM, bSize >::Query = std::array<double, kDIM>

Broadcast the query definition.

Constructor & Destructor Documentation

KdtSurfaces()
