CERN Accelerating science



The visualization working group develops and maintains the Geant4 systems for vizualizing geometries, trajectories and hits. These systems include the core visualization interfaces plus a large number of specific visualization drivers to provide a wide variety of graphics capabilities. The visualization working group advises users on how best to exploit the available tools and how to integrate Geant4 visualization into any pre-existing software framework.
