Detailed Description

Demonstrates usage of geometry aliases - merge ALICE ITS with ATLAS MUON.

void geom_alias()
{
gEve->RegisterGeometryAlias("ALICE", "http://root.cern.ch/files/alice.root");
gEve->RegisterGeometryAlias("ATLAS", "http://root.cern.ch/files/atlas.root");
auto node1 = gGeoManager->GetTopVolume()->FindNode("ITSV_1");
auto its = new TEveGeoTopNode(gGeoManager, node1);
auto node2 = gGeoManager->GetTopVolume()->FindNode("OUTE_1");
auto atlas = new TEveGeoTopNode(gGeoManager, node2);
// EClipType not exported to CINT (see TGLUtil.h):
// 0 - no clip, 1 - clip plane, 2 - clip box
v->GetClipSet()->SetClipType(TGLClip::EType(2));

void AddGlobalElement(TEveElement *element, TEveElement *parent=0)
Add a global element, i.e.
TGeoManager * GetGeometryByAlias(const TString &alias)
Get geometry with given alias.
TGLViewer * GetDefaultGLViewer() const
Get TGLViewer of the default TEveViewer.
void RegisterGeometryAlias(const TString &alias, const TString &filename)
Register 'name' as an alias for geometry file 'filename'.

If global TEveManager* gEve is not set initialize it.
void FullRedraw3D(Bool_t resetCameras=kFALSE, Bool_t dropLogicals=kFALSE)
Perform 3D redraw of all scenes and viewers.
