|
|
// G4CoupledTransportation is an optional process to transport
|
|
// a particle, in case of coupled navigation in parallel geometries
|
|
// i.e. the geometrical propagation will be done
|
|
// encountering the geometrical volumes of the detectors and
|
|
// those of parallel geometries (eg for biasing, scoring, fast simulation)
|
|
// It is tasked with updating the "safety" to reflect the geometrical
|
|
// distance to the nearest volume, and the time of flight of the particle.
