RootGeoManager: A faster VPlacedVolume -> TGeoNode lookup (!358) · Merge requests · VecGeom / VecGeom · GitLab

Sandro Christian Wenzel requested to merge swenzel/faster_tgeonode_lookup into master Nov 10, 2016

VPlacedVolumes have unique (contiguous) integer ids
Use this property to speed up VPlacedVolume -> TGeoNode lookups (which will be needed for any attempt to put VecGeom navigation behind a TGeo interface)
