Not smooth enough
Needs more “auxiliary” points from field integrator
Or re-compute step
Requires expertise from transportation
Invoke by augmented user command?
/tracking/storeTrajectory smooth
Avoid user tracking action class

Includes smooth
Extra information via G4AttValues
Volume and next volume
Process that created trajectory
Total step energy deposit
Process that limits step
Invoke by augmented user command?
