  3 This example demonstrates integration of the navigation elements of
  4 [VecGeom](https://gitlab.cern.ch/VecGeom/VecGeom), to investigate the
  5 performance benefits.
  6 
  7 This integration is in development. Supporting Placement volumes -- other
  8 volumes would be handled by existing Geant4 navigation.
  9 
 10 The example loads a GDML file for the geometry, and can execute a batch
 11 file (vecgeomNav.in) or run interactive commands or both.

 13 # Installation / Configuration
 14 
 15 ## Dependencies
 16 
 17 In addition to Geant4, two projects: are required VecGeom and G4VecGeomNav.
 18 VecCore is also required, but can be found through VecGeom.
 19 
 20 It is optionally possible to use Root in G4VecGeomNav to store voxel
 21 information for safety computation.  These can require significant computation
 22 to calculate if at least one logical volume contains many daughter volume.
 23 
 24 ## Configuration
 25 - To configure you must set:
 26 
 27      setenv CMAKE_PREFIX_PATH "${VECCORE_DIR}:${VECGEOM_DIR}"
 28 
 29 or if you are using Vc from Root
 30      setenv CMAKE_PREFIX_PATH "${ROOTSYS}:${VECGEOM_DIR}"
 31 where VecGeom has also been built with the same installation of Vc from Root.
