  Herwig 7 is a general-purpose Monte Carlo generator of particle collisions
comprising both hard perturbative as well as soft phenomenological physics.
Herwig is therefore capable to describe the entire final state of hadronized
particles in a collision event. A spacetime topology of a parton system
entering hadronization is fully described and tested for the first time. A
combination of information from particles momenta and spacetime positions is
utilized to minimize a boost-invariant distance measure of the parton system.
We present a reasonable agreement of the model with a selection of experimental
data and conclude that spacetime event topology can be meaningfully used in the
further development.
