curvature

Vector3 Acts::NavigationArguments::curvature = Vector3::Zero()

Local geometric curvature d(direction)/ds in global coordinates, in inverse length units.

Perpendicular to the unit tangent, with magnitude 1/R for the local curvature radius. Unchanged by reversing propagation direction. Zero denotes straight motion.
