REveGeomViewer and tutorial Viewer.C removed in 6.28/

ROOT Version: 6.28
Platform: Linux
Compiler: gcc 8.5

I notice that REveGeomViewer and the tutorial Viewer.c which uses it has been removed from 6.28, having been present in earlier releases. Is there a reason for this?

I’m afraid you now need to use: grep -r -l RGeomViewer ${ROOTSYS}/tutorials
Note: “${ROOTSYS}/tutorials/eve7/viewer.C” is now “${ROOTSYS}/tutorials/geom/web_cms.cxx”.

REveGeomViewer class was renamed to RGeomViewer and moved into separate library.
Just to avoid need loading of extra REVE code.

RGeomViewer is automatically activated when root --web is started.
In that case calling gGeoManager->GetTopVolume()->Draw("ogl") will automatically starts web-based viewer

Thanks for the prompt replies.
