Detailed Description

Plain navigator options carrying geometry context and surfaces.

Member Typedef Documentation

FreeSurfaceSelctor_t

using Acts::NavigatorPlainOptions::FreeSurfaceSelctor_t

Initial value:

 Delegate<bool(
      const GeometryContext& gctx, const TrackingVolume& currentVol,
      const Vector3& pos, const Vector3& dir, const Surface& candidate)>

Delegate to decide whether free surfaces are appended to the navigation stream given the current volume and the track coordinates.

If the delegate is set, it is called in each candidate resolution step for each surface that has not been marked as reached yet.

Parameters

gctx	Current geometry context carrying the alignment information
currentVol	The current tracking volume in which the propagator resides
pos	Position of the track in global coordinates
dir	Direction vector of the track
surface	Free surface candidate to test

Parameters

gctx	The geometry context
