Class Acts::KDTreeTrackingGeometryBuilder¶
-
class KDTreeTrackingGeometryBuilder : public Acts::ITrackingGeometryBuilder¶
A Tracking Geometry builder restricted to cylindrical geometries.
It takes some helper tools and a vector of surface objects, together with a ProtoDetector description that is used to query a KDTree for contained surfaces in structures defined by the proto volume.
Public Types
-
using SurfaceKDT = KDTree<2u, std::shared_ptr<Surface>, ActsScalar, std::array, 100>¶
Public Functions
-
KDTreeTrackingGeometryBuilder(const Config &cfg, std::unique_ptr<const Logger> logger = getDefaultLogger("KDTreeTrackingGeometryBuilder", Logging::INFO))¶
Constructor.
- Parameters
cfg – [in] is the configuration struct for this builder
logger – [in] logging instance
-
virtual std::unique_ptr<const TrackingGeometry> trackingGeometry(const GeometryContext &gctx) const final¶
TrackingGeometry Interface method.
- Parameters
gctx – geometry context of that building call
- Returns
a unique pointer to a TrackingGeometry
-
struct Config¶
Nested Configuration for this TrackingGeometryBuilder.
