Detailed Description

Shows CMS geometry in stereo mode.

This requires quad-buffer support in the OpenGL hardware / driver, otherwise a fatal error occurs.

gGeoManager = gEve->GetGeometry("http://root.cern.ch/files/cms.root");
auto top = gGeoManager->GetTopVolume()->FindNode("CMSE_1")->GetVolume();
auto trk = new TEveGeoTopNode(gGeoManager, top->FindNode("TRAK_1"));

auto calo = new TEveGeoTopNode(gGeoManager, top->FindNode("CALO_1"));
